草莓植株形态与其果实的相关性研究

Studies on the Correlation between Plant Morphologh and Its Fruit in Strawberry

对亚洲型、欧洲型、美洲型及自育草莓品种果实大小与其它１２个性状的相关分析和回归分析结果表明，花冠径、叶面积、花茎粗、株高、花瓣面积与果实大小呈极显著正相关；花茎长、花萼面积与果实大小呈显著正相关；花茎直立度、熟性与果实大小、叶形指数与果形指数。

Asia type, Europe type, American type strawberry and the strawberry varieties bred by us were studied in this experiment. The strawberry fruits were classfied into four types such as extra big, big, middle and small type. Phenotypic correlation and regression analysis loere conducted with 18 strawberry cultivars for their performance of fruit size and other 12 characters. The results showed that the most significant positiue correlation existed among corolla diameter, leaf areas, floral stem thickness, plant height, petal areas and fruif size; Significant positiue correlation was found among floral axis length, calyx areas and fruit size; Closely correlation among floral stem erection olegree, maturity and fruit size was found. At the same time, there was closely correlation among leaf shape index, fruit shape, leaf color and fruit color.
