The effect of supraoptimal temperatures (30 degrees C, 35 degrees C) on germination and ethylene production of Cicer arietinum (chick-pea) seeds was measured. Compared with a 25 degrees C control, these temperatures inhibited both germination and ethylene production. The effect of supraoptimal temperatures could be alleviated by treating the seeds with ethylene. It was concluded that one effect of high temperature on germination was due to its negative effect on ethylene production. This inhibitory effect of high temperature was due to increased conjugation of 1-aminocyclopropane-1-carboxylic acid to 1-(malonylamino)cyclopropane-1-carboxylic acid and to an inhibition of ethylene-forming enzyme activity.
测定了超适宜温度(30摄氏度、35摄氏度)对鹰嘴豆种子萌发和乙烯生成的影响。与25摄氏度的对照相比,这些温度抑制了种子的萌发和乙烯生成。用乙烯处理种子可减轻超适宜温度的影响。得出的结论是,高温对萌发的一种影响是由于其对乙烯生成产生负面影响。高温的这种抑制作用是由于1-氨基环丙烷-1-羧酸与1-(丙二酰氨基)环丙烷-1-羧酸的结合增加以及乙烯形成酶活性受到抑制。
