![]() Each hybrid and each cuttings time were conducted in a single experiment. The other cutting times at 135 and 165 days were taken to study the largest number of cutting which can be produced. These studies were conducted in factorial experiments in a randomized complete block design with three replicates for each, during the seasons of 012 at a nursery in Badrashein City, Giza Governorate, Egypt. Cutting times 105 and 195 days were planted in speedling trays. ![]() The cuttings of all times were treated with 3 concentrations of IBA, i.e., 0, 100 and 200 ppm to promote the adventitious roots formation. Mother plants were treated with 3 concentrations (0, 10 and 20 ppm) of BA for four times, i.e., after 75, 105,135 and 165 days to maintain and improve the physiological status of the mother plants. Cuttings were taken from these mother plants, at four time intervals, i.e., 105,135,165 and 195 days from transplanting. The second type was cuttings included one node, bud and leaf. The first type was cuttings from terminal growing point of the main stem and lateral branches 10 to15cm in length and 0.45 to 0.6 cm in diameter. Buttercup (QV 766) F1 (yellow flesh) and SSX 7402 F1 hybrid (red flesh) were taken from stock plants planted under optimal conditions and treated before as mother plant for cuttings at 45 and 75 days from transplant. For these reasons, the present investigation aimed to propagate seedless watermelon by cuttings produced from stock plants (mother plants) and to study the effects of BA and IBA concentrations and cutting types and the interactions between them on the cutting success. The growing costs of seedless watermelon (triploid hybrids) in Egypt are very expensive because of its high seed price, seeds do not germinate well and they show less homogeneous germination and growth. The interaction between IBA and cutting types gave significant effect on the survival percentage only.Ĭutting is one of the most important methods of vegetative propagation. ![]() IBA and types of cuttings individually showed significant effects on the cuttings success as a survival percentage, roots formation and number and length of roots. The bilateral and triple interactions among container types, IBA concentrations and cutting types did not show any significant effect. The same results were obtained for the number and length of roots in the first and second seasons in both hybrids under study. Cuttings included one node gave a higher survival percentage of cuttings than the terminal cuttings. IBA concentrations exhibited a significant positive effect on the survival percentage and roots number and length. The results showed no significant differences between both types of containers in all the characteristics in both seasons. The first and second cuttings were planted in two types of containers, viz., speedling trays and pots (8 cm), The study was conducted in factorial experiments in randomized complete block design with three replicates during two successive seasons 012 at a nursery in Badrashein City, Giza Governorate, Egypt. The cuttings were treated with 3 concentrations of IBA, viz., 0,100 and 200 ppm to promote the adventitious root formation. Two periods of cuttings were taken from these mother plants, at 45 and 75days from transplanting. Two types of cuttings were used the first type was cuttings from terminal growing point of the main stem and lateral branches with 10 to15 cm in length, 0.4 to 0.6 cm in diameter and the second type was cuttings included one node, bud and leaf. Yellow Buttercup (QV 766) F1 (yellow flesh) and SSX 7402 F1 hybrid (red flesh)) were used in this study. This technique depends on taking the cuttings from mother plants planted under optimal conditions. The present study was conducted to propagate seedless watermelon by cuttings and study some factors affecting success of the watermelon cuttings propagation. Cuttings are an important method of vegetative propagation. ![]() Vegetative propagation is widely used to multiply some horticultural crops. ![]()
