草莓主要植株性状指标及其相互关系的研究

本试验用栽前根状茎粗度分级法对塑料大棚条件下,栽植的不同根状茎粗度的草莓叶片数、花蕾数和产量进行田间测定.结果表明:随着茎粗的增大,叶片数和花蕾形成数量呈显著增大,产量显著增加.茎粗与叶片数、花蕾数、产量之间;叶片数、产量、花蕾数之间;叶片数与花蕾数间均呈极显著相关关系:r茎粗-叶片数=0.8992HS,r茎粗-花蕾数=0.9086HS,r茎粗-产量=0.9620HS,r叶片数-产量=0.7564HS,r花蕾数-产量=0.9467HS,r叶片数-花蕾数=0.7871HS,本试验确定出各指标相互间的六种回归关系,最后确定出草莓产量形成的最佳茎粗是1.1621cm,最佳叶片数是3.7352,最佳花蕾数是10.0419(个).

STUDIES ON SEVERAL PLANT MORPHOLOGICAL INDICES AND THEIR RELATIONSHIP IN (F. ANANASSA DUCH) STRAWBERRY

The lear number, flower bud number, prodution/per plant in strawberry plant of the different ryizome thick that were cultived in greenhouse were measured and analysied as follows: the leaf number, flower bud number, prodution/per plant increase with the ryizome thick, the relationship of the indices was significent: R(ryizome thick-leaf number)= 0.8992HS, R(ryizome thick-flower bud number)=0.9086HS, R(ryizome thick-production/per plant)=0.9620HS, R(leaf number-production/per plant)= 0.7564HS, R(flower bud number-production/per plant)=0.9467HS, R(leaf number-flower bud number)=0.7871HS, the regression equation was defined as Y=ax~3+bx~2+cx+d, by the method of regression here were analysied that optimum ryizome thick was 1.1621cm, optimum lear number was 3.7352, and optimum flower bud number was 10.0419 in this research.
