一、前言三十烷醇(1—triacontasl)作为一种新型植物生长调节剂,自1977年以来,在国内外广泛推广应用于水稻、玉米、小麦、花生、大豆、甘薯、蔬菜、茶树等二十多种作物上(莫家让,1982)。大量的试验研究证明三十烷醇具有促进生长,提高多种酶的活性,增强呼吸强度,增强光合,促进光
I. INTRODUCTION As a new plant growth regulator, 1-triacontasl has been widely used in rice, corn, wheat, peanut, soybean, sweet potato, vegetable and tea tree at home and abroad since 1977 More than ten kinds of crops (Mo Jiaotong, 1982). Numerous experimental studies have shown that triacontanol can promote growth, increase the activity of various enzymes, enhance respiratory intensity, enhance photosynthesis, promote light
