The Effects Of Planting Time And Overshadow On Florescence And Flowering Traits Of Lily

Lily is a perennial bulb plant in lilium of the liliaceae family.The needs of potted lily is huge during the holiday and winter,the market price is high.Potted Lily deveolpment started late,the development time is short,so the varieties is limit,plant height is too high.The study of regulation florescence is important for achieve market supply.In this research regulation florescence based on change the planting time and overshadow.Results show:Through plan different varieties lily,the floresence is preliminary staggered.'Tiny Pearl''Tiny Double You' 'After Eight''Sunny Bonaire' 'Sunny Okinawa' and `Entertainer' of 6 varieties were observed and found the floresence is differences,flowering time in June to August,Flowering time sequentially arranges for 'Tiny Double You''Tiny Pearl''After Eight''Entertainer''Sunny Okinawa''Sunny Bonaire'.In Flowering Traits,the number of bud length of 'Tiny Double You' 'Tiny Pearl''Sunny Bonaire' and 'Entertainer' is more than others,the number of bud length can reach 6-8 in a single flower.The single flower period of 'Tiny Pearl' is longest,The length of flower of 'After Eight' is longest.The effects of planting time for florescence is different following the varieties.'Tiny Doule You' and 'After Night' are planting interval 2w,but they bloom 7d and 3d in advance.The planting time of 'Tiny Bee' 'Tiny Ghost' and 'Tiny Invader' is March 16,2015and January 17,2016,they bloom respectively 39d,42d,55d in advance.Overshadow have certain effect on Lily florescence and flowering traits.Most of the shadeearly flowering,'Entertainer' and 'After Eight' ahead of the biggest,reached 11d and 13d,'Sunny Bonaire' 'Sunny Okinawa' 'Tiny Pearl'in advance respectively for 7d,4d,3d,but the early flowering of 'Tiny Double You' was postponed for Id.The singleflowering period of'Tiny Double You' and'Sunny Okinawa' did not change.From the view point of the groups of flowering,except 'After Eight' is not affected by light intensity,the other five have extended.One of the longest extension is'Sunny Bonaire'(5d);'Tiny Double You' extended shortest time(1 d).In addition,the light intensitycan affect the lily buds length,petal length and the diameter of the flower.The buds length of 'TinyDouble You' in full sunlight was significantly greater than that in the shade.In the shade,the budlength of 'Tiny Pearl' 'Sunny Okinawa' and 'After Eight'was significantly greater than under fullillumination,'Sunny Bonaire' and 'Entertainer' are not sig nificant.The light intensity does not affectthe lily petal width.
