Effects of inflorescence bud removal on bulb quality for Oriental Hybrid Lilium ＂Sorbonne＂ and Oriental × Trumpet Hybrid Lilium ＂Manissa＂ | 摘蕾对百合品种“索邦”和“黄天霸”种球质量的影响

Chino. 东方百合杂种系的“索邦”（Sorbonne）和OT杂种系的“黄天霸”（Manissa）在我国百合切花生产中占有重要的地位，因此，研究其种球生产技术，是解决种球生产国产化的基础。为生产大规格种球，以“索邦”和“黄天霸”12～14cm的鳞茎为材料，研究在种球生产过程中，花蕾摘除时期对其鳞茎大小和营养成分的影响。结果表明：“索邦”在花蕾1cm时摘除最好，种球鲜重平均达49．16g，围径平均达16．93cm，植株高度平均达62．10cm，可溶性总糖含量（FW）平均达到63．47mg／g，蔗糖含量（FW）平均达到57．93mg／g，淀粉平均含量（FW）为219．54mg／g，与对照形成极显著差异；“黄天霸”在花蕾1～2cm时摘除效果最好，其中，1cm摘除花蕾收获的种球鲜重量为55．31g，围径平均为17．12cm，植株高度达70．17cm，可溶性总糖含量（FW）达到75．60mg／g，蔗糖含量（FW）达到68．16mg／g，淀粉含量（FW）为257．53mg／g。对于2个品种，在开花当天摘除花蕾和花开放后摘除的效果较差，均低于对照。[著者文摘]

Inglés. ＂Sorbonne＂ and ＂Manissa＂ are very important cultivars in the cut flower market. Therefore, the study of bulb production technology is helpful to solve the problems of bulbs domestic production. In order to produce large size bulbs, small bulbs of 12-14 cm were chosen for the experimental materials. The effects of inflorescence bud removal at different time on bulb quality were studied. The results showed that there was significant difference between cultivars. For Oriental Hybrid Llilium ＂Sorbonne＂, it was the best removing period when inflorescence bud was at 1 cm, the average weight of bulb was 49.16 g, the circumference was 16.93 em, the height of plant was 62.10 cm, the soluble sugar content（FW） was 63.47 mg/g, the sucrose content（FW） was 57.93 mg/g and the starch content（FW） was 219.54 mg/g. For Oriental × Trumpe Hybrid Liliurn ＂Manissa＂, the best period was at 1 cm and 2 cm, when removing inflorescence bud was at 1 cm, the average weight of bulb was 55.31 g, the circumference was 17. 12 cm, the height of plant was 70. 17 cm, the soluble sugar content（FW） was 75.60 mg/g, the sucrose content（FW） was 68.16 mg/g and the starch content（FW） was 257.53 mg/g. In both of the two cultivars, when removing buds at flowering time and 5 days after flowering, the bulb size and nutritive substance were less than the control.[著者文摘]
