红光、远红光和植物激素对水稻幼苗生长及CAT、POX活性的影响

EFFECT OF RED OR FAR-RED LIGHT AND PLANT HORMONE ON THE GROWTH AND ACTIVITY OF CAT, POX IN SEEDING OF RICE

  • 摘要: 红光(R)和远红光(Fr)都抑制水稻胚芽的生长,但对胚芽鞘来说,红光抑制其生长,远红光表现出部分逆转效应。一定浓度单一生长素(IAA)促进水稻胚芽鞘的生长,而赤霉素(GA3)与生长素作用相反。对于水稻的过氧化氢酶(CAT)、过氧化物酶(POX),红光促进两种酶的活性,远红光则表现出逆转效应。单一10-2ppmIAA、10-2ppmGA3都促进其活性。照光时,在10-2ppm IAA存在的条件下,红光表现为促进,远红光则表现为抑制;但在10-2ppm GA3存在的条件下,红光反而对两种酶的活性有抑制作用,远红光则表现为促进作用。

     

    Abstract: Both Red(R) and Far-red light(Fr) inhibit the growth of embryonic bud of rice As for embryonic bud sheath, R inhibits its growth, Fr shows partial reversible effect. The single IAA of certain concentration encourages the growth of sheath, but the effect of GA3 is opposite to that of IAA. As far as CAT and POX of rice is concerned, R encourages their activity, however, Fr shows the effect of reversibility. Both the single 10-2 ppm IAA and the single 10-2 ppm GA3 encourage the activity of CAT and POX. The result that plant hormone and light are given simultaneously is complex. In 10-2 ppm IAA, R shows its encouragement, while Fr shows its inhibition; but in 10-2 ppm GA3, on the contrary, R inhibits their activity and Fr demonstrates its encouragement.
