钙对月季切花保鲜效应的初步研究

切花保鲜的关键技术是降低水分的散失和防止营养的亏缺。以月季为材料,采用室内瓶插的方法研究CaCl2对月季切花的形态影响。测量了切花月季的有关外观形态特征,结果表明：在基础液中加入不同浓度的CaCl2对切花月季有一定的保鲜作用,可延长切花月季瓶插寿命,增加切花鲜重,增大开放花径,增加切花的吸水量。所有处理都比对照的保鲜效果要好,处理中以2?Cl2＋2%蔗糖＋500 mg/L柠檬酸的溶液保鲜效果最佳。

Primary Study of Effect of Ca on Fresh Preservation of Cut Rose

The pivotal technique of flower preservation is to decrease water shedding and prevent the loss of nutrition.The preservation effect of CaCl_2 on cut rose was studied.Outward appearance quality of cut rose was measured,indicating that addition of CaCl_2 in the preservation solutions could prolong vase-life,increase fresh weight and flower diameter of cut rose,increase water uptake.All treatments produced better effect than that of contrast,The best treatment solution was 2 ?Cl_2 2 %sugar 500 mg/L citric acid.
