| 摘 要： | 嫁接瓜果实发育过程中，叶内蔗糖含量和干物质积累显著高于自根瓜，自根瓜和嫁接瓜的叶中蔗糖含量与酸性转化酶（AI）、蔗糖磷酸合酶（SPS）活性均呈显著正相关；嫁接瓜果实中蔗糖含量显著低于自根瓜，SPS活性和果实中糖分的跨液泡膜运输能力亦较自根瓜低；自根瓜和嫁接瓜叶的干物质积累与叶中AI和SPS活性、果实AI活性呈显著负相关，与液泡膜H^＋-ATPase活性呈显著正相关。 |

| Abstract: | During fruit development,the dry matter accumulation and sucrose content were markedly higher in leaves of grafted watermelon than those of own-rooted watermelon.There were good positive correlations among the acid invertase (AI) activity,sucrose phosphate synthase (SPS) activity and sucrose content in leaves of grafted and own-rooted watermelon.The sucrose content and SPS activity and sugar trans-membrane transportation capability in the fruits of grafted watermelon were significantly lower than those of own-rooted watermelon.There were negative correlations between AI activities in leaves and fruits,SPS activity and dry matter accumulation in leaves of grafted and own-rooted watermelon.There were good positive correlations between tonoplast H+-ATPase activity and dry matter accumulation in fruit of grafted and own-rooted watermelon. |
| Keywords: | grafted watermelon fruit development leaf fruit sucrose metabolism |
