花卉在人们生活质量日益提高的今天发挥着越来越来大的作用。如何延长采后花期是当前收获后加工技术中的一个集中研究热题。切花采后花期的长短与植物体内糖分有直接关系。如何控制切花中的糖分是其保鲜技术的重要一环。该文就本人的试验结果进行了分析 ,并着重论述了糖分的有害作用。先将温室玫瑰 (品种 :Mercedes)放置水中 ,然后配备溶液 (ABA (No.10 12 ,Sigm a,USA) + Al2 (SO4) 3+ 16 H2 O +白砂糖 )进行试验。采后玫瑰的花瓣和叶子自始至终均用电子天平精确纪录其质量 ,以示其变化。在整个试验过程中 ,该玫瑰均在恒温室内进行 (温度为 2 2℃ ,光照为 14h/d,12μE/s x m- 2 )。由于糖分起到了能量补充的作用 ,适量施加糖分对延长花期有明显的效果。但必须根据花卉的不同种类、品种和条件等来合理使用和控制糖分才能达到应有的效果。 ABA关闭叶孔的作用明显 ,合理使用 ABA是花卉保鲜的关键。糖分不宜过量 ,否则会造成叶细胞间积糖 ,出现叶面斑点和“黑脖子”现象。
Flowers are playing an increasingly important role today as people’s quality of life rises day by day. How to prolong post-harvest flowering is a concentrated research hot topic in post-harvest processing technology. Cut the flowering and postharvest sugar content of the plant body has a direct relationship. How to control the sugar in cut flowers is an important part of its preservation technology. This paper analyzes the results of my tests and focuses on the harmful effects of sugars. The Greenhouse Rose (Species: Mercedes) was placed in water and then equipped with a solution (ABA (No.1012, Sigm a, USA) + Al2 (SO4) 3 + 16 H20 + Sugar). Post-harvest rose petals and leaves are used electronic balance accurate record of its quality, to show its change. Throughout the experiment, the rose was kept in a thermostatic chamber (temperature of 2 ° C, light of 14 h / d, 12 μE / s x m-2). As sugar has played a role in energy supplement, the amount of sugar to extend the flowering period has a significant effect. However, flowers must be properly used and controlled according to different types, varieties and conditions of flowers to achieve the desired result. ABA leaf holes close the role of obvious, rational use of ABA is the key to fresh flowers. Sugars should not be excessive, otherwise it will cause interstitial cell sugar, leaf spots and “black neck” phenomenon.
