摘  要:
以生长在新疆乌恰县境内的新疆沙冬青种子为研究对象,进行了种子特性以及萌发条件优化选择的初步研究,结果表明其果荚天然虫蛀率为63.67%,籽粒天然虫蛀率为25.16%,籽粒天然结实率为76.21%,籽粒的种径大小为长(6.232±0.14)mm,宽(4.917±0.25)mm,厚(1.609±0.1)mm,瘦籽率为3.15%,饱满种子千粒重为35.63g,瘦籽千粒重为18.36g。根据所测定的各处理的种子发芽率和种子发芽指数高低来优化选择最适宜的种子萌发条件,优化选择的结果种子播种深度为2cm、土壤含水量为20%、温度与光照条件为30℃/10℃,14h/10h。

摘  要:
Seed characteristics and germination condition of Ammopiptanthus nanus were studied, the result was shown that the vermiculous ratio of fruit and seed in field were 63.67% and 25.16% respectively, setting percentage was 76.12%, size of seed was (6.232±0.14)mm×(4.917±0.25)mm×(1.609±0.1)mm, ratio of imperfect seed was 3.15%, and weight of one thousand perfect and imperfect seed was 35.63 g and 18.36g respectively. The optimal germination condition was 2cm in depth in river sand, sand moisture was 20%, illumination condition was 14 h/10 h (day/night), temperature was 30 ℃/10 ℃.
