摘 要 ：水青树是一种稀有珍贵树木。它的种子没有休眠,对光的反应随温度而异,25℃时不需光,24—33℃(多在28—30℃)喜光,10—20℃光对发芽有促进作用。最适发芽温度为25℃。经冬季低温层积的种子,可在1.4—8.2℃的低温中发芽。硝酸钾能部分解除种子发芽对温度的要求,GA也略有这种作用。以上结果不仅对水青树的种子检验和播种育苗有实用价值,同时在光温和化学处理对发芽的影响方面,有一定的理论价值。

Abstract:Tetracentron sinensis is a valuable tree which is rare. Its seeds have not dormancy. Its reaction to light is different at temperatures, at 25℃ no lightdemanding, at 24—33℃ （most at 28—30℃） light-favored and at 10—20℃ light can promote germination. Optimum germination temperature is 25℃; Seeds which had been cold stratification could germinate in 1.4—8.2℃. KNO₃ could partly relieve temperature demand in seeds germination, GA had this action in just a little.
