    ABSTRACT: Thamnocalamus falconeri, Hook.f. ex Munro., an important bamboo species belonging to the family Poaceae, locally known as Ringal, occurs in the hills of Uttarakhand, India. This species has been traditionally exploited by local communities to support their livelihoods. Increasing needs of the hill villages impose unsustainable pressure on natural stands of Ringal in the Uttarakhand hills and forests have been degraded. The long history of excessive cutting of Ringal from natural forests and the lack of replanting threaten villager livelihoods. Replanting is required to conserve the species. We propose a protocol for generation of planting material through axillary bud proliferation for multiplication and conservation of this species. We collected offsets/rhizomes from a natural stand of T. falconeri in the Chopta Mandal areas (Chamoli district, India). These were planted at sites of varied elevation and fresh single nodal segments were collected from them as explants. Different sterilization treatments were assessed to combat contamination. Among these, treatment of 0.1 % HgCl2 followed by 5 % NaOCl, proved best. Among two cytokinin treatments, viz. BAP and Kinetin, singly or in combination, BAP alone (5 mg L−1) proved superior and resulted in 100 % bud break. BAP-supplemented MS media yielded maximum vigorous shoot formation (90 %) and maximum number of shoots (8.9). Subculturing of shoots on the same medium with similar BAP treatment (5 mg L−1 BAP) enabled continuous production of healthy shoots at similar frequency. Maximum rooting (100 %) was recorded on half-strength MS medium supplemented with 5 mg L−1 IBA. Micropropagated plants were hardened and acclimatized in soil mixture (2:1:1) and then transplanted to field sites (Magra, Uttarakhand, 1,834 m). Eight to ten months after field transplantation we recorded 100 % survival of transplanted material. This micropropagation protocol could be used successfully for raising a stock of genetically homogenous plant material in bulk for field plantations and for conservation of the species.

    ABSTRACT: We studied relationships between stand structure and stand stability according to thinning intensity in an afforested oriental beech stand. Various thinning intensities were applied in sample stands. We sampled eight plots in stands that were lightly thinned, eight plots in heavily thinned stands and eight plots in unthinned stands as a control. Height and diameter distributions of the stands were measured to assess stand structure. We quantified individual tree stability and collective stability. Heavy thinning during the first thinning operation damaged the storied structure of the stand in thicket stage and affected collective structuring ability. While most control plots had multi-storied stands, after light and heavy thinning two-storied structure became more common. Large gaps occurred in the canopy after heavy thinning. On average, nine tree collectives were formed per sampling plot in the untreated stand, seven collectives after thinning in 2008 and four collectives after thinning in 2009. Stable trees accounted for 17 % of trees in control plots, 24 % in lightly thinned plots, and 15 % in heavily thinned plots. Collective stability values were 83 % in control plots, 82 % in lightly thinned plots and 36 % in heavily thinned plots. We conclude that it is necessary to retain collective structuring capacity during thinning operations for sustaining stand stability.

    ABSTRACT: Bamboo residues were liquefied in a mixture of glycerol and methanol in the presence of sulfuric acid using microwave energy. We investigated the effects of liquefaction conditions, including glycerol/methanol ratio, liquefaction temperature, and reaction time on the conversion yield. The optimal liquefaction conditions were under the temperature of 120 °C, the reaction time of 7 min, the glycerol–methanol–bamboo ratio of 8/0/2 (W/W), and the microwave power of 300 W. Maximum conversion yield was 96.7 %. The liquid products were separated into two contents (water soluble part and precipitate part) by addition of a sufficient amount of water. By Fourier transform infrared (FT-IR), the water soluble content mainly contained glycerol and its derivate and carbohydrate degradation products, and the precipitate content was mainly lignin derivatives.

    ABSTRACT: To generate carbon credits under the Reducing Emissions from Deforestation and forest Degradation program (REDD+), accurate estimates of forest carbon stocks are needed. Carbon accounting efforts have focused on carbon stocks in aboveground biomass (AGB). Although wood specific gravity (WSG) is known to be an important variable in AGB estimates, there is currently a lack of data on WSG for Malagasy tree species. This study aimed to determine whether estimates of carbon stocks calculated from literature-based WSG values differed from those based on WSG values measured on wood core samples. Carbon stocks in forest biomass were assessed using two WSG data sets: (i) values measured from 303 wood core samples extracted in the study area, (ii) values derived from international databases. Results suggested that there is difference between the field and literature-based WSG at the 0.05 level. The latter data set was on average 16 % higher than the former. However, carbon stocks calculated from the two data sets did not differ significantly at the 0.05 level. Such findings could be attributed to the form of the allometric equation used which gives more weight to tree diameter and tree height than to WSG. The choice of dataset should depend on the level of accuracy (Tier II or III) desired by REDD+. As higher levels of accuracy are rewarded by higher prices, species-specific WSG data would be highly desirable.

    ABSTRACT: This paper presents preliminary assessment of seedling survival and growth of green alder (Alnus viridis (Chaix) DC. in Lam. & DC.) planted on fly ash disposal sites. This kind of post-industrial site is extremely hard to biologically stabilize without top-soiling. The experiment started with surface preparation using NPK start-up mineral fertilizer at 60–36–36 kg ha−1 followed by initial stabilization through hydro-seeding with biosolids (sewage sludge 4 Mg ha−1 dry mass) and a mixture of grasses (Dactylis glomerata L. and Lolium multiflorum Lam.) (200 kg ha−1). Subsequently, three-years-old green alder seedlings were planted in plots on two substrate variants: the control (directly on combustion waste) and plots with 3 dm3 lignite culm from a nearby mine introduced into the planting pit. Five years of preliminary monitoring show good survival seedling rates and growth parameters (height (h), average increase in height (Δh), number of shoots (Lo) and leaf nitrogen supply in the fly ash disposal habitat. Treatment of the site with a combination of lignite culm in planting pits and preliminary surface preparation by hydro-seeding and mineral fertilization had the most positive effect on green alder seedling parameters. The results indicate that it is possible and beneficial to use green alder for biological stabilization on fly ash disposal sites.

    ABSTRACT: Chinese fir (Cunninghamia lanceolata (Lamb.) Hook) is one of the most important coniferous tree species used for timber production in China. Here, we conducted a sequence-related amplified polymorphism (SRAP) primer screening assay with a total of 594 primer combinations, using 22 forward and 27 reverse primers on four representative Chinese fir genotypes. The obtained results indicated that Chinese fir genomic DNA has a notable amplification bias on the employed forward or reverse primer nucleotides (3′ selection bases). Out of the tested primer sets, 35 primer combinations with clearly distinguished bands, stable amplification, and rich polymorphism were selected and identified as optimal primer sets. These optimal primer pairs gave a total of 379 scorable bands, including 265 polymorphic bands, with an average of 10.8 bands and 7.6 polymorphic bands per primer combination. The produced band number for each optimal primer set ranged from 7 to 14 with a percentage of polymorphic bands spanning from 33.3 to 100.0 %. These primer combinations could facilitate the next SRAP analysis assays in Chinese fir.

    ABSTRACT: We prepared spherical microcapsules modified by carboxymethyl cellulose (CMC) with urea-formaldehyde (UF) resin as a shell material with a two-step process by in situ polymerization, and characterized the microcosmic features, chemical structure, and thermal performance of the microcapsules by SEM, FTIR, DSC, and TGA. We studied the effects of different experimental parameters of curing pH, the amounts of the emulsifier and emulsion speed. The CMC-UF microcapsules had good heat resistance and stability. The enthalpy of CMC-UF microcapsules reached 50.33 J g−1. Therefore, CMC-UF resin can be used as a potential wall material of phase change materials.

    ABSTRACT: In addition to pests and diseases, weeds are a major problem in poplar nursery production. The possibilities of herbicide application in juvenile poplar growth were researched, taking into account that weeds are one of the main limiting factors. The following pre-emergence herbicides were tested: acetochlor, S-metolachlor, metribuzin, oxifluorfen, and dimethenamid during two vegetation seasons at two locations, which differed by the soil physicochemical characteristics. The study results show that the number of weeds on sample plots was significantly reduced by the tested herbicides when compared to control plots. The highest reduction in the number of weeds was achieved using the herbicides acetochlor and metribuzin. However, metribuzin showed a phytotoxic effect on sandy soil. Metribuzin application is recommended only on the soils with higher contents of organic matter, where the phytotoxic effect was absent. Acetochlor, S-metolachlor, oxifluorfen, and dimethenamid were not phytotoxic to poplars and can be used for weed suppression in the production of poplar plants.

    ABSTRACT: Both fecundities and egg hatchabilities were compared among three populations of Dastarcus helophoroides Fairmaire adults (Coleoptera: Bothrideridae) fed on three types of artificial diets (Diet of formula 1 composed of silkworm pupa powder, dried yeast powder, sucrose, peptone, egg yolk powder and poplar branch powder. Diet of formula 2 composed of silkworm pupa powder, dried yeast powder, sucrose, egg yolk powder, poplar branch powder, cricket powder, benzoic acid and distilled water. Diet of formula 3 composed of pine bark powder and Monochamus alternatus larva powder). for 90 days. The three diets showed no significant difference regarding the average number of eggs deposited by all D. helophoroides females (16622.3–23874.7); the average number of eggs per female (1278.6–1836.5); and the average number of eggs per female per day (14.2–20.4). The number of eggs one cluster contained mainly (82.06–82.66 %) lied in 1–100 eggs, and the average number of eggs per cluster ranged from 61.7 to 63.1. In the first 10-day period, the number of eggs deposited by all females fed on formula 1 was significantly larger than that on formula 3. The eggs deposited in the last four 10-day periods were more than in the former five 10-day periods, on formula 3. There were no significant differences in hatchability of total eggs among the three artificial diets, and the average corrected egg hatchability ranged from 82.85 to 84.78 %. No significant differences in the adult mortality and mean weight gain of D. helophoroides were found after feeding on three artificial diets. Our results suggest that D. helophoroides adults were not specialized on the diet, and the diet types might have little effect on fecundity and egg hatchability in D. helophoroides, as long as sufficient nutrition was supplied.

    ABSTRACT: Investigations were made to determine the nature and extent of variations present for 10 morphological characters of cone, seed and seedlings of 17 plus trees (PTs) of Pinus kesiya growing in eastern Himalayas (Meghalaya state) of India. The significant variations has been observed in cone weight, cone length, cone diameter, seed length, seed diameter, seed weight, number of seeds per cone, seed germination, seedling height and seedling collar diameter among different PTs of the species. Significant positive correlation (p P. kesiya depend more on the cone size. Seed germination is found positively correlated (p p P. kesiya also showed a wide range of variability in terms of variance, coefficient of variability, broad sense heritability, genetic advance and genetic gain. Seed weight, seeds per cone and seedling diameter showed high heritability values (>75) coupled with maximum genetic gain. Traits with such values indicate the presence of good amount of heritable additive components and are under strong genetic control. The findings of the study revealed that PTs expressed both phenotypic and genotypic differences in the seed, cone and seedling characters, which may be attributed to the differences in genetic makeup of various PTs and environmental factors i.e. genotypic and environmental interaction. The presence of high variability in P. kesiya PTs for different characters provide further opportunities to improve the population in subsequent generations so as to establish this species as an important timber tree to be grown on less fertile and degraded soils in its distributional ranges.

    ABSTRACT: Phellodendron amurense has been used for many years as a medical plant in traditional Chinese medicine and has shown great prospect in recent clinical trials for future applications. Berberine is an essential active compound contained in P. amurense. Our objective in this study was to quantify the content of berberine in P. amurense from sites at different elevations on Changbai Mountain. We collected samples of P. amurense from five different elevations on Changbai Mountain. Berberine in samples was extracted by ultrahigh pressure extraction (UPE). And the quantity was measured by high performance liquid chromatography (HPLC). First, the optimal HPLC conditions for berberine were identified with satisfactory precision (relative standard deviation, R SD R E R 2 = 0.9998) in the range of 6.576–328.8 mg·L−1. Second, the combination of UPE and HPLC methods in quantitative analysis of berberine showed high repeatability (R SD = 3.28 %), reproducibility (R SD = 4.72 %), stability (R SD HPLC method is simple, reliable and low-cost for quantitative analysis of berberine. Content of berberine in P. amurense varied significantly by site on Changbai Mountain.

    ABSTRACT: We evaluated the biomass and ergosterol content of Hericium erinaceus mycelium, and extracellular enzyme activities in H. erinaceus liquid culture following salicylic acid (SA) and methyl jasmonic acid (MeJA) supplementation. The optimal SA concentration was 100 µmol·L−1, where the highest ergosterol content of 2.33 mg·g−1 was obtained following 6-day cultivation with 100 µmol·L−1 SA supplementation, and which was significantly higher than the unsupplemented control (p −1 MeJA, the highest ergosterol content obtained was 1.988 mg·g−1, which was 25.8 % higher than the unsupplemented control. Our data indicate that SA and MeJA supplementation improves ergosterol content in H. erinaceus mycelium.
