旱胁迫对啤酒大麦产量及酿造品质的影响
Effects of drought stress on the yield and quality of malting barley
摘要
Abstract
Influences of drought stress on growth period ,agronomic characteristics ,grain yield ,quality and malt quality of barley variety Ganpi 6 were systematically investigated in this research .The results showed that under drought stress ,all growth periods of Ganpi 6 were advanced ,survival rate was reduced ,tiller number was decreased ,and plant height ,ear length ,panicle number per plant ,grains per plant ,seed weight per plant ,grain weight per panicle ,and seeds per ear were decreased .The yield of Ganpi 6 was decreased due to the drought stress that caused reduction of ear number ,grains per spike and 1000-grain weight .In addition ,ear number was affected the most ,followed by k grains per spike ,and the 1000-grain weight was least impacted .Drought stress increased the protein content ,and decreased 1000 grain weight ,starch content and the screening rate .However ,the decreasing level of 1000 grain weight was higher than that of screening rate and starch content ,and the decreasing level of starch content was the minimal .Also ,drought stress decreased malt saccharifying time ,diastatic power ,viscosities ,β - glucanase ,fine powder extract and the thick-ness difference of powder ,whereas increased coarse powder extract ,α - amino nitrogen soluble nitrogen ,protein ,and kolbach index .关键词
