PEG-6000对不同黑麦草品种萌发期抗旱性的影响
Influence of PEG-6000 on D rought Resistance of Different Ryegrass Cultivars in Germination Period
摘要
Abstract
In order to screen fine perennial ryegrass cultivars fit to be planted in Hunan areas,seed relative germination rate,relative germination energy,relative germination index,relative seed vigor index and contents/germ value among 1 3 different types of ryegrass cultivars were analyzed and assessed synthetically under analogue drought condition with polyeth-ylene glycol (PEG-6000)at the density of 0,5%,1 0%,1 5%,20%. The results showed that the cultivars with strong drought resistance of ryegrass cultivars in seed germination period were Barwoltra,Especially high,Oregon tetraploid;the cultivars with medium drought resistance of ryegrass varieties in seed germination period were YaQing,Pandora,Resist rust king,Premier,Night shadow Ⅱ,Peak,Swords,McGrady and Pinnacle;the resistance of Winter green was the worst.关键词
