embryogenic calli production in vitis is mainly possible by use of such regenerative tissues as anther and ovary. because of long periods of time required for obtaining such tissues, use of such vegetative organs as leaf explant would be a promising alternative. towards this end, leaf explants were taken from two varieties of ‘flame seedless’ and ‘red sultanina’ to be raised in. ms medium, cons...

The aim of this study was to determine the effects of different plant growth regulators, NAA (0 mg/l, 50 mg/l and 100 mg/l) and GA3 (0 mg/l, 50 mg/l and 100 mg/l), with various boron concentrations (0 mg/l, 50 mg/l and 100 mg/l) on pollen germination of ‘Şaba’, ‘Rabie’ and ‘Padre’ almond cultivars in 10% sucrose and 1% agar medium at 24°C in dark conditions. The results showed that different tr...

Two factorial experiments were conducted to study the interactive effects of four levels of sucrose (0, 20, 40 and 60 g l-1), two levels of citric acid (0 and 160 mg l-1) and two levels of one of the following compounds (aluminum sulphate, 0 and 160 mg l-1 and silver nitrate, 0 and 120 g l-1) on vase life and quality attributes of lisianthus cut flowers ‘Mariachi blue fonce.’ The experiments ca...

Generally, narcissus is propagated through vegetative methods, but due to their low yield their are not economical. This study was conducted to develop a suitable method for the production of somatic embryos and bulblets in Narcissus papyraceus cv. Shirazi. Bulb scales were placed on the MS medium supplemented with 2,4-D and BAP each at 0.0, 0.25, 0.5 or 1 mg/l concentrations to form somatic em...

Effects of exogenously applied methyl jasmonate (MeJA) and sucrose on vase life and non-structural carbohydrate concentration in petals and leaves of cut ‘First Red’ roses were investigated. Roses were placed in sealed plastic containers and received MeJA vapour treatment (0.1 μL MeJA L-1) for 24 h at 20°C. Flowers were then placed in individual bottles containing 0 or 2% (v/v) sucrose solution...
