不同处理对四种草坪种子发芽的影响

Effects of Four Species of Lawn Seed Germination in Different Treatments

本文采用正交试验设计，研究了硝酸钾、赤霉素浸种对剪股颖、紫羊茅、黑麦草、狗牙根种子发芽的影响。主要考查了发芽势、发芽率。简化活力指数等指标。实验数据及分析结果表明：黑麦草以0．1％KNO3、紫羊茅以0．3％KNO3、狗牙根以300g／LGA3＋0．1％KON3处理效果较好，剪股颖以不处理为好。

Orthogonal experiment has been done on effects of seed germination in different GA3 and KNO3 soaking of Agrostis palsutis,Festuca arundine, Lodium prenne and Cynodon dactylon. It was principally examined germination energy, germination percentage and simplified vigour index. The results are surmmarized as follows: Lokium prenne using 0. 1%KNO3, Festuca arundine 0. 3%KNO3,Cynodon dactyion 300ppm GA3+0. 1 %KNO3 can improve germination and Agrostis palsutis no treadting is good.
