百合种子萌发和幼苗生长观察

对百合野生种、栽培品种及杂交种种子恒温箱和沙床萌发及生长情况进行观察。结果表明:在恒温箱中野生种种子的萌发率较高,普遍在80%以上;栽培品种中麝香百合没有萌发,"布鲁拉诺"、"莱诺"和"马拉客奇"的萌发率都在80%以上,"托里诺"的萌发率较低,为55%;杂交种子中只有"米雷拉"×"托里诺"、"托里诺"×"米雷拉"、"莱诺"×"托里诺"杂交种子能萌发且萌发率都在70%以上。沙床萌发试验中,亚洲百合和以亚洲百合为亲本的杂交种子出苗率最高,其次是渥丹,毛百合没有出苗;大多数百合种子在播种后3～4d开始萌发,在播种后30d左右出现真叶;子叶和真叶的生长基本上都遵循"先快后慢"的规律。

The Observation of Lilies Germination and Growth Status

The germination and growth status of wild lily species,cultivars and hybrids cultured in incubation box and sand through the germination experiment of these lilies in the constant temperature box were studied.The results showed that the germination rate of the wild species were higher,and all above 80%;For the cultivars,the L.longiflorum.did not germinate,Asiatic lily cv.Brunello and Asiatic lily cv.Marrakech’ s germination rates were all above 80%,the germination rate of ‘Torino’ was lower,only 55%;For the hybrids,the germination rates of ‘Mirella’ × ‘Torino’,‘Torino’ × ‘Mirella’ and ‘Lainuo’ × ‘Torino’ germinated,and the germinate rate were all above 70%.Through the sand cultivation experiment,found that the emergence rate of Asiatic hybrids and their hybrids were the highest,the next was L.concolor,but L.dahuricumdid not emerge;most lilies seeds emerged after sowing 3～4 days,and the leaves appeared about after sowing 30days;the growth of the cotyledon and foliage was in the regulation of ‘fast at first and then slow’.
