摘要
通过定时、定株来进行实地调查、观察野皂荚枝、花、荚、种子及根系的生长发育规律。结果表明,野皂荚为雌雄异株、自花不育树种。新梢4月中旬开始生长,5月上、中旬生长最快,日平均生长量1 04cm,6月上旬停止生长。根系发达,主要分布层在5～70cm处,占总根量的77 8%。萌芽力强。盛果期大树多数枝条成为结果枝,而且连续结果能力很强。结果枝的长度、粗度与每果穗结果的莱数、种粒数呈显著正相关。
The growth and development of branch, flower, pod, seed and root system of Gleditsis microphlla was observed. Results show that this tree species is dioecious and self sterile. Its soft branches start to grow in the midlle of April, and cease to grow in early June, and the fast growing appeared in the first and second ten-day periods of May with average daily growth of 1.04cm.Its root system is much developed, and mainly distributed in the soil layer of 5~70cm under soil surface which accounts 77.8%of the total roots. The tree species has string capacity of generation. The majority branches of the big trees in full fruit period could develop as fruiting ones, and could fruiting continuously. The length and diameter of fruiting branch is found significantly related to the amounts of pod and seed.
