影响鲜食子莲产量的形态指标相关分析和通径分析

对影响"南四湖"鲜食子莲产量的形态指标进行了相关和通径分析.结果表明,影响鲜食子莲莲子产量的主要形态指标与产量的相关程度依次为;莲蓬重(0.953 6)、莲蓬径(0.810 3)、莲子径(0.761 4)、莲子重(0.713 1)、果皮重(0.677 8)、成熟度(0.638 3)、莲子高(0.565 1)、莲子数(0.411 2),对产量的直接影响重要性依次为:瘪种子数(-0.456 4)、莲子重(0.450 1)、莲蓬重(0.434 2)、莲子数(0.266 5)、莲蓬径(-0.093 7)、莲子径(0.076 5)、成熟度(0.041 4)等;形态指标间具有明显的制约关系;并提出了增加子莲产量的策略和技术.

Correlation and Path Analysis on the Morphological Index and Output of the Fresh Seedy Lotus

The correlation and path analysis on morphological index and output of the fresh seedy lotus which were picked from Nansihu Lake were conducted,and the results indicated that the relativity of morphological index and output as in turn: weight of lotus (0.953 6),diameter of the lotus(0.810 3) .diameter of the lotus seed(0.761 4),weight of lotus seed(0.713 1),weight of lotus seed peel (0.677 8) .maturity (0.638 3) .height of lotus seed (0.565 1),number of locus seeds (0.411 2).The importance of the direct factors to the output were in turn:number of hollow(-0.456 4) .weight of lotus seed(0.450 1),weight of lotus(0.434 2),number of locus seeds(0.266 5) .diameter of the lotus(-0.093 7),diameter of the lotus seed(0.076 5) .maturity (0.041 4),and so on. Also,it indicated that the morphological indices had the obvious restricted relations.Finally,the strategy and the technology of the high production of seedy lotus were suggested.
