研究了预处理和瓶插处理方式下不同浓度６－ＢＡ对‘四季黄’切花菊瓶插期间花与叶的水分状况等生理效应和瓶插寿命的影响，参数包括：含水量、相对紧张度及饱和亏缺、气孔开度、叶绿素和可溶蛋白动态等。结果表明，６－ＢＡ延衰保鲜作用与上述指标密切相关，预处方式下低浓度６－ＢＡ、特别是１ｍｇ／Ｌ对瓶插品质及寿命影响效果最好，瓶插方式下，超过１ｍｇ／Ｌ即出现抑制效应。讨论了６－ＢＡ缓解叶片早萎的现象。
The effects of different concentrations of 6-BA on the physiological and floral characteristics of flowers and leaves and the vase life during bottle insertion of ’Sijihuang’ cut chrysanthemum were studied under the pretreatment and bottle insertion treatments. The parameters included: water content, relative stress And saturation deficit, stomatal opening, chlorophyll and soluble protein dynamics. The results showed that the effect of 6-BA delayed preservation was closely related to the above indexes. The effect of 6-BA, especially 1mg / L, on the quality and life span of vase was best under the pretreatment mode. L that inhibit effect. The phenomenon of 6-BA alleviating premature wilt of leaves was discussed.
