Chinese. 以本育9、平安18、丰禾10、四单19为试验材料，研究氮素用量对春玉米淀粉合成关键酶的影响。结果表明，ADPG焦磷酸化酶和淀粉分支酶（Q酶）是春玉米淀粉合成的关键酶；施纯氮200kg/hm. 处理是提高春玉米ADPG焦磷酸化酶活性和提高本育9、平安18、四单19Q酶活性的最佳处理；施纯氮100kg／hm. 处理是提高丰禾10Q酶活性的最佳处理。[著者文摘]

The results showed that ADPG-PPase and Q enzyme were the key enzyme in composing starch. N 200 kg/ha was the best disposal to Q enzyme activity of Benyu9, Pingan18, Sidan19, N 100 kg/hawas the best disposal to Q enzyme activity of Fenghe10.
