    ABSTRACT: A hydroponic study to evaluate the role of exogenous application of abscisic acid (ABA) and salicylic acid (SA) levels (H0=no spray, H1=only 1 Mm SA, H2= only 2µM ABA and H3= combine spray of 1 Mm SA+2µM ABA) against the salt stress on rice grown under saline (70 mM NaCl) and non-saline (0 mM NaCl) was conducted in DGK campus of the university of Agriculture Faisalabad, Punjab, Pakistan. Evaluation was done on various morphological (root length, shoot length, root fresh, shoot fresh weight, root dry weight, shoot dry weight, root shoot ratio) and biochemical parameters (sodium and potassium contents). Statistical analysis of data revealed that the exogenous application of ABA and SA significantly improved the salinity tolerance in rice. The response of plant to salinity tolerance was maximum where hormones (SA and ABA) were applied separately as compared to their combined or no application. Key Words: Rice, Salt stress, Hormones, Salt tolerance, Hydroponics

    ABSTRACT: Effects of drought stress were induced by polyethylene glycol (PEG-6000) (10, 20, and 30%) for 2, 4, 6 and 8 days in Apocynum venelum L. seedlings with the potting method. The results showed that PEG significantly increased the activities of glutathione reductase (GR), superoxide dismutase (SOD), ascorbate peroxidase (APX), and the contents of electrolyte leakage rates, MDA, proline and soluble sugar were increased from 30% PEG. Thus, it was indicated that the application of exogenous 30% PEG induced oxidative damage by enhancing antioxidant defense systems.

    ABSTRACT: Carlini copticuni L. comprises several relevant species for food, cosmetic, perfumery and pharmaceutical industries. GC/MS analysis of the enential oil of C. copticum revealed gamma- terpinene as a major component of C. copticum, with its contribution of 33.85%. Essential oils (EOs) exhibited a significant antimicrobial activity against all tested microbial strains. In addition, the C. copticum oil demonstrated the highest DPPH radical scavenging activity. These results clearly show the antimicrobial and antioxidant effects of the plant essential oil.

    ABSTRACT: Saline-alkaline (Usar) soils have high pH and undesirable salts on their surface. A halotolerant, heterocystous and nitrogen fixing cyanobacterium Nostoc calcicola Breb. BREB grow successfully on saline-alkaline soils of Eastern Uttar Pradesh. Soil pot experimentation has been conducted in laboratory condition to study the reclamation of saline-alkaline soils collected from investigated site. Both sterilized and natural soils were taken in earthen pots to observe the changes in soil properties inoculated with cyanobacteria and gypsum. In such treated soils significant decrease in pH, ECe and Na+ have been observed with cyanobacterial application. There also occurs a significant increase in organic carbon. Experimental reclamation of such soils has been found with cyanobacteria with or without gypsum. N. cczlcicola + gypsum seem to be a suitable combination for reclamation of saline-alkaline soils. This study highlights that a biological amendment with halotolerant cyanobacteria and gypsum in combination shows better option for bioremediation of saline-alkaline (Usar soils).

    ABSTRACT: Analysis of variance revealed significant differences among the genotypes for all the traits. Flag leaf area (0.643**), productive tillers per plant (0.450**), 1000-grain weight (0.785**) and harvest index (0.920**) showed positive and strong significant association with grain yield per plant at genotypic level whereas plant height (-0.418*) and per cent spikelet sterility (-0.489**) possessed significant negative correlation with grain yield per plant. Flag leaf area (0.157) productive tillers per plant (0.481), 1000-grain weight (0.228), growth duration (0.080) and harvest index (0.544) exhibited direct effect on grain yield. Considering the correlation and path analysis flag leaf area, productive tiller per plant, 1000-grain weight and harvest index are important characters to be considered for yield improvement.

    ABSTRACT: To determine the succession after a fire that occured in 1997 in the vicinity of Cekem and Halfeti villages, near Sanliurfa, Turkey work was carried out. The floristic changes in the area were observed during first six years and in the tenth year after the fire. The dominant species of burnt vegetation had a tendency to return towards a state similiar to the existined before fire. Most of the species prior to fire (98.7%) reappeared within the first six years and the vegetation nearly reached the prefire physiognomy. At the end of ten years, no significant differences in term of floristic composition and physiognomy were observed.

    ABSTRACT: The phenology of Angelica palustris seeds including maturation, germination requirements, and dormancy class, is still unknown. In opposite to the results reported from other species of Angelica, present findings showed that A. palustris produced seeds with embryo underdeveloped (the ratio between the embryo and the whole seed length was between 0.19 and 0.12) and physiologically dormant which corresponded to Morphophysiological Dormancy class. Dormancy breakdown requires a post maturation period (at least 30 days) at 18 - 20 degrees C for a complete embryo development, and also up to 30 days of cold stratification at 4 degrees C. The best germination indices were obtained when fruit was removed. Germination energy (Ge) was achieved within 19 days after imbibition and was 25.8 +/- 0.03 and germination per cent (Gp) was achieved within 28 days and was 64.7 +/- 0.14. Fruit structure (lateral wings with air cavities) and physiology (essential oil production) are adaptations to facilitate seed dispersal and dormancy/germination balance.

    ABSTRACT: Action sites of low positive temperature together with high light intensities in electron transport reactions of photosystem II (PSII) evaluated by ms range delayed fluorescence (ms-DLE) of chlorophyll a content in the maize and barley seedlings are presented. The main targets for these stress factors action were shown to be Y-z and Mn4OxCa-cluster on the donor site of PSII in the case of simultaneous action of different temperatures and high light illumination and between Q(A) and Q(B) on the acceptor site of PSII in the case of low positive temperature influence only.
