山桐子育种苗期试验初报

A preliminary study on growing seedlings of Idesia polycarpa Maxim

育苗试验结果表明 ,山桐子在亚热带地区能正常生长发育 ,其种子发芽需经过去蜡处理。在塑料薄膜棚内 ,约需 40d才能形成幼苗。苗期生长呈慢—快—慢的曲线变化规律 ,11月生长趋于停止。 1年生苗高 78～ 112cm ,平均 86 6cm ;根径 1 1～ 1.7cm ,平均 1 5cm。

The seedlings of Idesia polycarpa Maxim. were raised at Ningbo Xikou of subtropical area in 1999,the things about which growing characters and adaptability were studied.The results showed that the seeds would sprout in about 40 days in plastic film arch.And seasonal growth of the seedlings took a curve of low,high and low again,and tended to cease in November.The height of one year old seedlings varied from 78 to 112 cm and the average was 86.6 cm;the collar diameter of those varied from 1.1 to 1.7 cm and the average was 1.5 cm.
