摘要： 研究结果表明，用尿囊素（All）处理小麦种子后，能提高其根系活力，增强根系对矿质养分和水分的吸收能力；促进分蘖，提高成穗率9.5%~12.7%；提高ATP酶和硝酸还原酶的活性；降低过氧化氢酶的活性。有利于小麦体内各种生理生化活动的进行，同时对延缓叶片衰老有一定作用；并能提高叶绿素含量，增加叶面积，增强光合强度，促进小麦体内的干物质累积。

Abstract: The mechanism of promoting wheat growth and increasing yield with allatoin (All) was studied. The results showed that after the wheat seeds were treated with All, the vitality of wheat root system was improved, its ability to absorb mineral nutrients and water increased, the seedling tiller ability was enhanced, the percentage of earbearing tiller increased by 9.5%-12.7%, the activities of nitrate reductase and ATPase strengthened, while the hydrogen peroxidase activity reduced. So that the biological and biochemical processes were carried out well in wheat tissues, the leaf senility delayed, the chlorophyl 1 content increased, the leaf area enlarged, the photosynthesis intensity strengthened, and the dry matters were greatly accumulated in wheat tissues.
