EFFECT OF BULB CUTTING, STORAGE METHODS AND HOT WATER TREATMENT ON THE PROPAGATION OF Narcissus tazetta PLANTS
The natural vegetative reproduction of narcissus plants under field conditions is very slow, as onion mothers produce few follicles, therefore increasing the production of the number of onions is one of the important things to improve the multiplication of narcissus bulbs. Therefore, during 2018 and 2019seasons in the laboratory of Sakha Horticultural Research Station, Egypt, an experimental research was performed to study the effect of cutting methods of bulb (chipping and twin-scaling), storage temperatures (pre-cooling and no pre-cooling) and hot-water treatments (hot water and no hot water) on the propagation of Narcissus tazetta cv. “Ziva” bulbs. The obtained results indicated that, chipping, pre-cooling and hot water treatments constantly affected the bulblet formation in both seasons and bulblet weight / chip in the first season only but had no effect on bulblets number. Chipping method improved all traits i.e. bulblet formation, fresh weight, circumference of bulblet and bulblets number / chip, leaves number and length as well as roots/chip. However, chipping caused in larger and fewer bulblets than twin-scaling. In the second season, pre-cooling was increased bulblet formation and both weight and circumference of bulblet and decreased number and length of leaves and roots. Hot-water treatments were increased bulblet formation but then number and length of leaves and roots were reduced. Conclusively, it could be recommended to applybulb cutting, pre cooling storage methods and hot water treatment on the bulbs to give the best results in propagation of Narcissus tazetta.
