摘要:

为应对多元化市场,满足不同客户对切花小菊品质的需求,本试验以切花小菊品种黄小为材料,设置5个摘心时间处理(停光后第2、4、6、8、10天),以不摘心为对照,研究摘心对开花时表型性状的影响。结果表明,与对照相比,摘心后黄小花苞数增加,一级分枝数减少,二、三级分枝数增加,整体丰满度更好。其中,停光后第8、10天摘心处理的开花花苞数和一级分枝数均高于停光后第2、4、6天处理;停光后第8天摘心处理的三级分枝数显著(p<0.05)高于第10天处理。综合比较,停光后第8天摘心的切花小菊黄小开花时整体丰满度最佳,符合国内客户需求;而未摘心黄小整体株型更加纤细、花头紧凑匀称,更加符合国外客户需求。

Abstract:

To diversify market offerings and meet the requirements of different customers for cut chrysanthemum quality,this experiment used the cut chrysanthemum cultivar Huangxiao as material,set five pinching time treatments(2,4,6,8,and 10 days after light cessation),with no pinching as the control,to investigate the effects of pinching on phenotypic traits at flowering. The results showed that compared with the control,pinching increased the number of flower buds and the numbers of secondary and tertiary branches,while decreasing the number of primary branches,resulting in better overall plant fullness. Among the treatments,the numbers of flower buds and primary branches in plants pinched at 8 and 10 days after light cessation were higher than those pinched at 2,4,and 6 days after light cessation;the number of tertiary branches in plants pinched at 8 days after light cessation was significantly higher than that at 10 days. Comprehensive evaluation indicated that pinching at 8 days after light cessation resulted in the best overall plant fullness in cut chrysanthemum Huangxiao at flowering,meeting the requirements of domestic customers;while the non-pinched plants had a more slender plant type with compact and well-proportioned inflorescences,better meeting the requirements of overseas customers.
