Abstract:
Taking lily bulbs of ‘Tresor’ produced in two regions,Gu Yuan in Hebei and Xinzhuang in Fangshan,Beijing,as experimental materials,the effects of various physiological indicators,including hormone contents (CTK,GA3,ABA,IAA),nutritional components (such as protein,soluble protein,total polysaccharides,glucose,sucrose,starch),and enzyme activities (SS-Ⅰ，SS-Ⅱ,α-amylase,β-amylase) on the scale cutting propagation of ‘Tresor’ lilies under different geographical origins and storage periods were studied by using scale cutting method，in order to provide reference for further improving lily bulb breeding technology.The results showed that the significant climatic differences between Guyuan and Fangshan resulted in variations in the nutrient content，starch enzyme activity，and endogenous hormone levels of the harvested lily bulbs.However，the initial time for microbulb formation and the duration required for all scales to complete microbulb formation showed no significant differences.Additionally，the nutrient content，enzyme activity，and endogenous hormone levels of lily scales changed with extended cold storage.The initiation time of microbulb formation did not vary significantly across storage periods，remaining at approximately 12-14 days.However，the microbulb formation cycle gradually shortened with prolonged storage，from a maximum of 36 days (bulbs stored for 3 weeks) to 22 days (12 weeks of storage，dormancy broken)，before increasing to 26 days (16 weeks of storage).These findings suggest that the occurrence of lily microbulbs is not correlated with the initial nutrient content，enzyme activity，or endogenous hormone levels of the scales post-harvest.Instead，the length of the cold storage period directly impacts the rate and duration of microbulb formation after scale cutting.Bulbs stored for 12 weeks exhibited the highest propagation efficiency.
