Influence of Plant Growth Regulators and Dark Pretreatment on Shoot Proliferation, Rooting and Acclimatization of Thorny Blackberry

Salinity stress is one of the most serious impacts of climate changes on agriculture production, especially in salt sensitive crop plants, like strawberry. Currently, the utilization of nanomolecules in agriculture is thought to be a useful strategy to compact abiotic and biotic stresses. This study aimed to investigate the effect of zinc oxide nan...

This study was conducted to investigate the effectiveness of SA (10 and 100 µmol) for induction of salinity tolerance of two potato genotypes "Proventa" and line "97-980" during vegetative and micro-tuberization stages. Results showed that decreasing of plantlet weight and length as well as microtuber weight under saline conditions differed accordi...

The present study was conducted during the period 2014-2016 at the greenhouse facilities of the Department of Horticulture, Faculty of Agriculture, Suez Canal University. The experiment tested the effects of growing three daughter plants (ramets) sizes based on crown diameter (large > 7 mm, medium 5-7 mm and small < 5 mm) in combination with three...

The effect of water deficit on concentrations of carotenoids was investigated in ripening tomatoes using HPLC-PDA. Fifteen different tomato cultivars were grown under three levels of water supply and unripe and fully-ripe fruits were harvested at different stages. Water deficit significantly affected several morphological and fruit yield-related pa...

Grafting is an alternative approach to reduce crop damage resulting from soil-borne pathogens and increase plant abiotic stress tolerance, which in turn increases crop production. The purpose of this study was to determine the effect of three grafting methods [Tongue approach (TAG), Hole insertion (HIG) and Side grafting (SIG)] on plant growth and...

Somatic embryo-like structures (SELS) were produced in vitro from leaf disk and petiole explants of two cultivars of strawberry (Fragaria x ananassa Duch) on Murashige and Skoog medium with different concentrations and combinations of 2,4-dichlorophenoxyacetic acid (2,4-D), 6-benzylaminopurine (BAP) and sucrose to check the embryonic nature of thes...

Research efforts on the possibility of applying grafting to improve yield and fruit quality of cherry tomato were very limited. The aim of the present study was to determine whether grafting could improve plant growth, yield and fruit quality (vitamin C and soluble solids content) of cherry tomato via monitoring the changes induced by different roo...

Impact of Grafting on Watermelon Growth, Fruit Yield and Quality Grafting is an alternative approach to reduce crop damage resulting from soil-borne pathogens and increases plant abiotic stress tolerance, which in turn increases crop production. The purpose of this study was to determine whether grafting could improve plant growth and fruit quality...

Leaf disks derived from either two-month-old GreenHouse-grown (GHD) strawberry plants or in vitro plantlets were cultured on MS media amended with 2 mg L(-1) Thidiazuron (TDZ), incubated for four weeks in the dark then for another four weeks under 16/8 h light regime. Regeneration capacity of leaf disks was compared to meristem-derived propagules i...

Dry seeds of common bean ( Phaseolas vulgaris L. cv. Nebraska) were subjected to 0, 2 and 32 Krad of gamma rays from a cobalt-60 source and salt stress treatments (0, 1000, 2000 and 3000 ppm) of NaCl. The shoot length of the plants was significantly reduced only at the highest level (3000 ppm) of NaCl, while the root length was significantly inhibi...

Responses of three cultivated genotypes (Castlrock, Oriet and Super Marmande) and three breeding lines (BL-1076, BL-1077 and BL-1079) of tomato (Lycopersicon esculentum) to NaCl stress were studied in callus and regenerated plants. Hypocotyl segments and true leaves were chosen as explants for callus induction and regeneration in vitro, respectivel...

Macro- and micronutrient levels were monitored during the in vitro tuberization of potato (cv. Alpha) in liquid medium of MS salts and vitamins supplemented with 8% sucrose and 5 mg·liter –1 kinetin under complete darkness at 18C. Microtubers were formed in 50% of the cultured jars at day 20 and reached their full size at day 60 of culture initiati...

Plant growth regulators applied in vitro affected strawberry plant performance ex vitro for a period of up to 4 months. Benzyl-adenine and gibberellin enhanced juvenile characteristics; in general, more runners and monofoliolate leaves were produced, net photosynthesis was reduced, leaf diffusive resistance was increased and, on occasion, flowering...

In previous abstracts (HortScience 23:707;24:121), ABA when added throughout the in vitro production cycle, reversed the tissue culture-induced rejuvenation of the day neutral strawberry `Fern'. Compared to benzyl adenine (BA) proliferated plants, ABA treated tissue culture-produced plants flowered earlier and had more adult leaf patterns. In the p...

Shoot regeneration from Rubus leaves was obtained on a medium containing MS salts, vitamins and sugars, Staba vitamins, casein hydrolysate (100 mg l–1) and 10 M thidiazuron. Shoot regeneration from Malus leaves was obtained on N6 rice anther medium with 5 M thidiazuron. In vitro pretreatment of source shoots with either colchicine or thidiazuron en...
