摘要
结荚期喷施0.01mM赤霉素(GA3)、0.05mMN6—苄基腺嘌呤(6—BA)、5mM脯氨酸(Pro)、3mM抗坏血酸(Vc)、10mM甘氨酸(Gly)、6mM乙烯利(Eth)等生长调节物质均可提高花生叶片叶绿素含量和净光合速率(Pn),增加叶片可溶性蛋白质(Pr)含量、降低叶片丙二醛(MDA)积累量,提高叶片超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)活性,延缓花生叶片衰老,提高产量。
Effects of growth regulators on leaf senescence in peanut were studied in this experiment. The results indicated that the foliar sprays of 0.01mM Gibberellic acid (GA 3), 0.05mM N 6—Benzyl adenine (6—BA), 5mM Proline (Pro), 3mM Ascorbic acid (Vc), 10mM Glycine (Gly) and 6mM Ethephon (Eth) at pod setting phase could significantly increase the content of chlorophyll and net photosynthesis rate (Pn) in leaves, enhance the soluble protein (Pr) content of leaves ,increase the activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and decrease the accumulated amount of malondialdehyde (MDA) in peanut leaves.It also delayed peanut leaf senescence and increased pod yield significantly.
