| 摘 要： | 用灰色关联法分析了农艺性状、抗病性、净光合速率与杂交辣椒营养成份之间关系的密切程度。结果表明,农艺性状与营养成份间总体关联度大小顺序为叶长、首花节位、株幅、叶宽、叶柄长、株高、果长、主茎高、果宽、肉厚、侧枝数。抗病性性状与营养成份间总体关联度大小顺序为疫病、CMV、TMV、疮痂病。净光合速率与营养成份间总体关联度大小顺序为结果中期、结果前期、结果后期。

| Abstract: | The correlativity between nutrient substance and agronomic characters or disease resistance or net photosynthetic rate was estimated in hybrid pepper by using the method of grey correlation degree. Results showed that the magnitude on grey correlation degree between various agronomic characters and nutrient substance was leave length, the first flower node, plant spread, leave width, leavestalk length, plant height, fruit length, main stem height, fruit width, fruit wall thickness, branches. The magnitude on grey correlation degree between disease resistance and nutrient substance was Phytophthora blight, CMV, TMV Bacterial scab of Capsicum. The order between net photosynthetic rate and nutrient substance was early fruit-bearing period, middle fruit-bearing period, later fruit-bearing period. |
