In this study the effects of different sucrose concentrations, and the combinations of jasmonic acid (JA) with auxins (IAA or NAA) or with cytokinin (2iP) on the bulb induction and rooting of in vitro plantlets of Hyacinthus orientalis subsp. chionophyllus Wendelbo, which is endemic in Turkey, were investigated. The effect of four different sucrose concentrations (30, 45, 60 and 90 g L-1) on bulb formation in tissue culture was investigated. These plantlets were cultured on MS medium supplemented with several concentrations and combinations of JA (0.0, 1.0, 2.0 mg L-1) and 2iP (0.0, 0.25 and 0.50 mg L-1), IAA or NAA (0.5, 1.0 mg L-1). In JA- 2iP treatment, the highest number of bulblets (13.7 number/explant) was obtained by the combinations of JA 1.0 mg L-1 + 2iP 0.25 mg L-1. Also, the largest bulblets with the mean diameter of 7.9 mm were found on MS medium supplemented with JA 2.0 mg L-1. In JA – Auxin treatment, the mean root number per bulblet was highest (17.9 number/explant) and root formation rate was maximum (81.14%) on MS medium supplemented with IAA 1.0 mg L-1 + JA 2.0 mg L-1.

The present study was conducted to investigate the vegetative propagation of Sansevieria trifasciata under ex vitro conditions. The experiment was conducted at the net house to select the best leaf segment among apical, middle and bottom portions of leaves and also to evaluate their performance in different potting media. Leaf segments were taken from apical, middle and bottom portions and planted in soil: compost at 1:0, soil: compost at 1:1 and soil: compost at 1:2 ratios. After 90 days, number of shoots per cutting (>1cm), number of shoot buds (

The gooseberry is one of the exotic fruit species most important in Colombia. Calcium has been shown to be important for quality maintenance in fruits and vegetables, as it prevents a number of physiological disorders reinforce the cell walls and stabilize cellular membranes. With the aim to increase the fruit calcium concentration, a completely randomized design with four treatments was performed: a control and three applications of CaCl2 (0.5%, 1% and 2%), with four replicates, for a total of 16 experimental units (EU). The fruit was collected at maturity stage 6 according to the standard Icontec NTC 4580, completely healthy and homogeneous. The fruit was subsequently stored at 21 ± 1 ° C (RH 45%). The application of calcium in the gooseberry fruits decreased mass loss, firmness and ATT. Calcium treated fruit showed an increase in SST. In contrast, the treatments did not affect color. The doses of CaCl2 tested delayed ripening and prevented fruit deterioration.
