摘要：以7年生长林4#油茶为试材,采用正交试验设计方法,于盛花期前喷施不同浓度配比的叶面肥及生长调节剂,分析其对油茶雄蕊形态特征及坐果率的影响。结果表明:花期喷施叶面肥及生长调节剂对油茶花药形态特征及坐果率有显著影响。其中施用0.2 g/L H3BO3+0.10 g/L KH2PO4+0.10 g/L 2,4-D最有利于花药的生长且对花粉表面纹饰影响最大,施用0.2 g/L H3BO3+0.05 g/L KH2PO4+0.20 g/L 2,4-D对极轴长/赤道轴长影响最大;施用0.15 g/L H3BO3+0.15 g/L KH2PO4+0.20 g/L 2,4-D对油茶坐果率的增幅最大,增幅达27.93%,坐果率为42.88%。可见,花期喷施一定浓度配比的叶面肥及生长调节剂对油茶雄蕊形态特征及坐果率有促进作用。
Using 7 years of Camellia oleifera ’Changlin 4#’ as test material, using orthogonal design method,spraying foliar fertilizer and growth regulator with different concentration ratio before flowering stage, and analyzing its effect on the morphological characteristics and fruit setting rate of stamens. Results showed that foliar application of foliar fertilizer and growth regulator have significant effects on the anther characteristics of C.oleifera. The application of 0.2 g/L H3BO3+0.10 g/L KH2 PO4+0.10 g/L 2,4-D is most beneficial to the growth of anthers and has the greatest influence on the surface texture of pollen. The effect of application 0.2 g/L H3BO3+0.05 g/L KH2PO4+0.20 g/L 2,4-D on the axial length/equatorial axis length maximum. Sprayed 0.15 g/L H3BO3+0.15 g/L KH2 PO4+0.20 g/L 2,4-D, C. oleifera has the biggest increases of the fruit setting rate that is27.93%, and the fruit setting rate is 42.88%. Thus, spraying a certain concentration of foliar fertilizer at flowering stage can promote the morphological characteristics and fruit setting rate of stamens C. oleifera.
