不同浓度多效唑对晋遗31大豆农艺性状和产量的影响
Leaf Spraying Paclobutrazol Improves Agronomic Traits and Yield of Soybean cv.Jinyi 31
摘要
Abstract
In this study, soybean cv. Jinyi31 were leaf sprayed with 0, 50, 100, 150, 200, 250, 300 and 350 mg·kg-1 Paclobutrazol respectively at V6 in 2010 and 2011. Soybean yield increased from 2. 22% to 21. 97% under 50-350 mg·kg-1 Pactobutrazol,and the highest yield of 4175. 40 kg · ha-1 was obtained under 200 mg · kg-1 Paclobutrazol. Leaf spraying Paclobutrazol decreased podding height and plant height, shortened internode length, increased branches, pods and seed weight. Results suggest that 200 mg · kg -1 is optimal Paclobutrazol concentration for ameliorating agronomic traits agronomic and improving yield of soybean.关键词
