华中五味子栽培条件下果穗生长发育动态规律研究

Ear Development of Orange Magnolia Vine under Cultivation Conditions

在秦岭北麓地区栽培条件下,对华中五味子果穗生长发育过程观察研究表明:其果穗生长动态呈现快、慢节律,生长期内有减慢现象,其粗度、长度、体积生长动态及加粗、伸长生长相互关系符合三次函数曲线。末花期——第二次生理落果期果穗体积增长最快,占总产量的90.6%,是产量和优质果品形成的关键时期,并对田间管理提出了指导建议。

Orange Magnolia vine has been cultivated near north area of Qinling mountains.The research on the ear development of it is of significance.The research result showed that its development starts early and fast but slow in life cycle.Its thickness,length and volume increase comply with the cubic function curve.Ear volume increased much more from the end of blossom to fruit drop,which takes up 90.6% of the total output.
