摘要: <正>通过大田和盆栽试验研究了光质及光照时间对银杏叶黄酮和内酯含量的影响。结果表明:长波段的光(如红光)不利于黄酮和内酯类物质的积累而有利于植株的生长;短波段的光不利于生长但有利于黄酮和内酯类物质的积累。光质也影响银杏叶光合速率、PAL活性和相对生长量的大小。光照时间对银杏叶黄酮和内酯类物质含量、PAL活性无显著影响,但对植株的光合速率和相对生长量有显著的影响。

Abstract: The variation in contents of IAA, ABA, GA1+3, ZR during the dormancy and germination of seeds of Paeonia lactiflora was measured in outdoor sowing and in 5℃ cold storage. The result showed, in open field, the contents of ABA of the seeds declined rapidly when hypocotyls began to grow and the contents of GA1+3 were from peak to low during the initial process of epicotyls growing. With the development of embryo, IAA and ZR contents were increased. In 5℃ cold storage, the seeds failed to germinate and cold storage could not reduce ABA contents. GA1+3 contents increased first and then decreased. The contents of IAA and ZR in 5℃ cold treatments were obviously lower than that in open field.
