Studies in regulation of life-cycle and high degree efficiency of flower production in showy lily

用低温和植物激素处理美丽百合鳞茎，测定鳞茎休眠强度和花的品质。80天的低温处理打破了鳞茎的休眠。GA3能打破休眠，BA处理能增加开花数。GA+BA处理对鳞茎的萌发和开花数也有促进作用，低温处理对鳞茎中阿坝、GA和可溶性糖含量也有一定的影响。鳞茎解除休眠后，阿坝含量下降，GA含量上升。打破休眠后，百合鳞茎中可溶性糖含量迅速增加，说明百合鳞茎中GA和阿坝的含量与休眠有关。细胞分裂素对百合花芽发育有诱导作用。用GA+BA处理可控制休眠、开花和提高花的品质。

Bulbs of showy lily (Lilium Speciocum) was treated with chilling and plant hormones, then intensity of dormancy and quality of flowers were determined. Dormancy of the bulbs were broken by 80 days of chilling. GA3 induced breaking of dormancy while number of flowers increased by BA treatment. GA+BA treatment also showed positive effects for bud break and number of flowers.ABA,GA and soluble sugar contents were checked in the bulbs during chilling treatment. Decline of ABA and increase of GA were detected in the bulbs when they were released from dormancy. Soluble sugar content also increased immediately after breaking dormancy.These results indicated that levels of GA and ABA were connected with dormancy of Lily bulbs. It was also indicated cytokinin induced flower bud development in Lily. Controls of dormancy, flowering and increasing of flower qualities may be performed by GA+BA treatment.
