辣椒杂种一代生化特性与农艺性状的灰色关联分析

Grey Relational Analyses between Biochemical Matter Contents and Agronomic Characters of Hybrids in Pepper

用灰色关联分析方法研究了辣椒雄性不育杂种一代农艺性状与单株产量间、花蕾、叶片中生化物质含量与农艺性状间关系的密切程度。结果表明,农艺性状与单株产量间关联度的大小顺序依次为株幅、株高、果长、结果数、单果质量、第一花节位、果宽和侧枝数,花蕾中生化物质含量与农艺性状间总体关联度的大小顺序依次为可溶性糖、可溶性蛋白质、过氧化物酶活性、脱落酸、生长素、游离脯氨酸和玉米素,叶片中生化物质含量与农艺性状间总体关联度的大小顺序依次为可溶性糖、过氧化物酶活性、游离脯氨酸、脱落酸、生长素、玉米素和可溶性蛋白质。

The correlativity between agronomic characters and yield per plant and between biochemical matter contents in flower buds and leaves and agronomic characters of CMS hybrids were estimated in pepper by using the method of grey correlation degree. Results showed that the magnitude on grey correlation degree between various agronomic characters and yield per plant was plant spread, plant height, fruit length, fruits per plant, weight per fruit, the first flower node, fruit width and branches per plant. The magnitude on grey correlation degree between various biochemical matter contents in flower buds and agronomic characters was soluble sugar, soluble protein, POD activity, ABA, IAA, free proline and ZRs. The order in leaves was soluble sugar, POD activity, free proline, ABA, IAA, ZRs and soluble protein.
