花生种子的萌发代谢与抗氰电子传递速率──兼与橡胶种子比较

用乙烯利和ＮａＣＮ预处理花生种子，实验结果表明：（１）乙烯和ＣＮ－都提高种子子叶的抗氰电子传递速率，同时乙烯还提高种子子叶的总呼吸速率以及ＥＭＰ－ＴＣＡ速率，ＣＮ－则降低种子子叶的总呼吸速率以及ＥＭＰ－ＴＣＡ速率。（２）乙烯提高种子子叶的蛋白酶、脂肪酶和过氧化氢酶活性并提高游离氨基酸和脂肪酸含量以及降低水溶性蛋白质含量；ＣＮ－则降低种子子叶的蛋白酶、脂肪酶和过氧化氢酶活性，并降低游离氨基酸和脂肪酸含量，但提高水溶性蛋白质含量。（３）乙烯提高暗萌发苗的单株鲜重，ＣＮ－则降低暗萌发苗的单株鲜重。 

Germinating Metabolism and Cyanide-resistant Electron Transport of Peanut Seeds-Concurrent Comparison with Rubber Seeds

Peanut seeds were pretreated with ethrel and NaCN to observe their germinating metabolism and cyanide-resistant electron transport. The results are given as follows.(1)Ethylene and CNraised cyanideresistant electron transport rate, and ethylene also raised total respiratory rate and EMPTCA- rate but CN- reduced total respiratory rate and EMPTCA rate in peanut cotyledons. (2) Ethylene raised activities of protease, lipase and catalase and content of free amino acids and fatty acid and reduced content of soluble proteins; CN- reduced activities of protease, lipase and catalase as well as content of free amino acids and fatty acid but raised content of soluble proteins in peanut cotyledons. (3) Ethylene raised but CN- reduced the fresh weight of each seedling which germinated in the dark.
