| Abstract:
Experiments were conducted to compare various methods of producing bulblets from bulbs of Ornithogalum saundersiae Bak. in vivo. The methods compared included scaling and use of cuttings, scooping, scoring or coring of bulbs. Treatments also included storage conditions for bulbs or bulb materials used. In scaling, comparisons were also made between scale pieces with or without a piece of the basal plate (disc) and twin scale pieces. The average number of bulblets per bulb produced by scooped bulbs, scales, cuttings, scored or cored bulbs were 40.7, 21.2, 19.8, 10.1 and 7.4, respectively. In scaling, scale pieces without a piece of the basal plate formed the largest and the highest number of bulblets compared to scale pieces with disc and twin scales. Initial storage of propagation materials in the open enhanced bulblet production compared to storage in the dark or under polyethylene sheeting. Flowered bulbs produced more bulblets than non-flowered bulbs. | |
