摘　　要：建始槭（Acer henryi Pax）是我国特有的槭树科野生彩叶树种。为了使这种珍贵的树种资源尽早得到开发利用，在对该树种资源分布及原产地生境调查基础上，开展了生态适应性、种子发芽特性、苗木生长规律等研究。结果表明：建始槭具有耐寒、抗高温、耐碱性土壤及喜光等特性。建始槭种子为浅休眠种子，干藏和沙藏均能发芽，但沙藏120 d的种子发芽快且整齐，发芽率高（89.6％）。建始槭1～5年生种子苗高生长量第2年和第3年最大，年净生长量分别为109.6 cm和123.3 cm，第4年后逐年下降；年内月生长表现为“慢－快－慢”的规律，生长高峰出现在6－8月。地径生长量第1年较小，第2－5年较快，均在1 cm以上；3～5年生苗月生长亦表现为“慢－快－慢”的规律，生长高峰出现在7－9月。表明在河南低海拔平原地区及省内外相似生态类型区进行建始槭引种栽培和应用是切实可行的。Acer henryi Pax is a specific wild colored species of Aceraceae in our country.In order to make this precious tree species developed and utilized as soon as possible,based on the investigation of the plant resource distribution and its primary environment,the ecological adaption,seed germination characteristics and the growth rules of seed-plants were studied.The results showed that Acer henryi Pax had the tolerance to cold,high temperature,alkaline soil,and enj oyed light.The seed of Acer henryi Pax was shallow dormant.The seed whether in dry storage or in sand storage,could sprout,but the seed germination in sand storage for 120 d was quick and neat,and germination rate was high with 89.6%. The growth rate of 1 to 5 years old Acerhenryi Pax seedings were high in the second year and the third year with 109.6 cm and 123.3 cm respectively,and that began to decline from the fourth year;the monthly growth showed“slow-fast-slow”rule in a year,the peak value was in June to August.The basal diameter was small in the first year,faster during the second to fifth year,which were more than 1 cm;the monthly growth of 3 to 5 years old seedlings also showed “slow-fast-slow”rule,the peak value was in July to September.It was feasible to cultivate and use Acerhenryi Pax in the low elevation＆amp;nbsp;plain and other similar ecological regions inside and outside Henan province.
