【摘要】 本文测定ＴＨＰＧＭＲ农垦 ５８Ｓ光敏感期叶片 ＡＴＰ含量和 ＲｕＢＰｃａｓｅ活力的变化。结果表明：（ １）当材料由暗期进入光期时， ＨＰＧＭＲ ５８Ｓ叶片中的ＡＴＰ含量在长日照下比短日照下低，而材料由光期进入暗期时则相反；对照品种农垦５８在长日和短日照下无明显差异；（ ２）ＨＰＧＭＲ ５８Ｓ叶片中的ＲｕＢＰｃａｓｅ活力在长日照下明显比短日照下低，而对照品种农垦５８差异很小。由此推测ＨＰＧＭＲ在不同日照条件下其代谢途径有所不同。更多还原

【Abstract】 The treatise concerns with the study on the changes of ATP contents and specific RuBPcase activities in the leaves of HPGMR Nongken-58S during photosensitive stages and the conventional variety Nongken-58(as a contrast ) .The results are as follows: (1).when the materials are taken into light period from dark period. the ATP content in the leaf of HPGMR 585 in long-day sunshine (LD ) is less than that in short-day sunshine (SD), but in contrary as the material taken into dark period from light period. The ATP content in the contrast Nongken-58 in LD is almost the same with that in SD at the same time.(2). The specific RuBPcase activity in the leaf of HPGMR 585 is clearly lower in LD than that in SD: and the activity of the contrast is nearly the same in LD with that in SD .According to above results .we suggest that there be different metabolic pathways in HPGMR in different length of sunshines(LD & SD).更多还原
