低磷胁迫下嫁接对西瓜生长早期磷素吸收和利用的影响
Effects of grafting on phosphorus uptake and utilization of watermelon at early stage under low phosphorus stress
摘要
Abstract
Watermelons were grafted on bottle gourd and pumpkin, effects of grafting on phosphorus up- take and utilization of watermelon at early stage under low phosphorus stress were studied by hydroponics. The results showed that grafting can enhance dry matter, leaf area and plant height of watermelon at early stage. And root morphological parameters and photosynthetic rate of grafted watermelon were superior to watermelon. Phosphorus uptake and utilization of grafted watermelon were higher than watermelon under low Phosphorus stress. Different rootstocks performed differently, watermelon grafted on pumpkin performed better than watermelon grafted on bottle gourd. So grafting can enhance phosphorus uptake and uti- lization of watermelon at early stage under low phosphorus stress.关键词
