1.Taxiphyllum taxiramenum(Titt.) Fleisch,a species of karst adaptive moss,was treated with different concentration gradient of PEG600(0,2.5%,5%,10%,15%,20%)for the study of its response to water stress,with the changes of the water content,free proline and chlorophyll etc.
通过使用不同浓度梯度PEG6000(0、2.5%、5%、10%、15%、20%)对喀斯特适生植物鳞叶藓Taxiphyllum taxiramenum(Titt.)收藏指正
2.The physiological effect of new FA antitranspirant on winter wheat was studied in field trials. The new FA antitranspirant was sprayed at ear filling stage at the concentrations of 0.5, 1.0, 1.5 and 2.0 ml·L-1. The results indicated that new FA antitranspirant increased nitrate reductase activity (NRA), free proline content, chlorophyll content and water content of leaf, thus drought stress can be mitigated.
在冬小麦灌浆期喷施新型FA 抗蒸腾剂,喷施浓度为0.5、1.0、1.5 和2.0 ml·L-1,研究其对冬小麦的生理调节作用。 结果表明,喷施新型FA 抗蒸腾剂可以提高硝酸还原酶活性、游离脯氨酸含量、叶绿素含量和叶片含水量,有利于减轻干旱胁迫。收藏指正
3.The results showed: free water/binding water of the all treatments of alternate partial root-zone drip irrigation less than conventional drip irrigation, and contents of chlorophyll, soluble protein and malondialdehyde (MDA) is higher than conventional drip irrigation, the treatments with low limits of alternate partial root-zone drip irrigation of 85% and 75% field water capacity saved water by 30.33% and 34.98 % respectively, and water use efficiency increased by 40.32% and 47.11% respectively, yield only decreased by 2.71% and 4.34%.
研究表明，交替滴灌各处理叶片自由水与束缚水的比值都小于常规滴灌，叶片叶绿素、可溶性蛋白和丙二醛含量均高于常规滴灌；交替滴灌灌水下限为最大田间持水量的85%和75%的处理分别比常规滴灌节约用水30.33%和34.98%，水分利用效率则比常规滴灌增加40.32%和47.11%，而产量仅下降2.71%和4.34%。收藏指正
