【摘要】 来自10 个省的喜树地理种源, 在浙江临安进行了苗期生长规律的研究。种子品质以云南昆明种源为最优: 净度89-3 % , 千粒质量71-26 g , 发芽率94 % , 发芽势83 % , 平均发芽速度7-2 d 。苗木生长6 月中旬进入速生期, 9 月为最高峰。1年生苗高生长量最优的有江苏南京种源(134-97 cm) 、福建屏南种源(133-97 cm) 和浙江丽水种源(132-18 cm) 。图1 表2 参2更多还原

【Abstract】 The study was made in Linan City of Zhejiang Province.The test seed of Camptotheca acuminata was from 10 provinces of China.Among of them,Kunming provenance gave excellent seed quality:pureness(89 3%),thousand grain weight(71 26 g),germination percent(94%),germinating energy(83%) and mean germination speed(7 2 d).The fast growing stage was in the middle June,and the peak value appeared in September.Height increment of yearling fall excellently into Nanjing provenance(133 97 cm),Pingnan provenance(133 97 cm) and Lishui provenance(132 18 cm).更多还原
