Abstract

Aims: This experiment was conducted to assess the effect of different chemical preservative in vase life and quality of gerbera cut flowers. Study Design: Completely Randomized Design (CRD). Place and Duration of Study: Department of Horticulture, Prithvi Secondary School, Nawalparsi (East), Nepal, between June 2023 and September 2023. Methodology: Eight different preservative solutions of different concentrations (i.e. 4% sucrose, 200 ppm citric acid, 200 ppm salicylic acid and 1% CaCl2) and their combinations including control treatment i.e. sole application of distilled water were replicated thrice. And, the parameters like water solution uptake, flower weight, flower diameter, stem bending and vase life was observed. Results: The study revealed that among seven different vase solutions, the combination of 4% sucrose + 200 ppm citric acid was found superior for all the parameters observed and supposed to be the most effective vase solutions for prolonging the vase life and reducing the postharvest losses in gerbera. Conclusion: For achieving better quality of gerbera cut flowers, they are better to be treated with sucrose in combination with citric acid or CaCl2, thus can satisfactorily be recommended for commercial growers, wholesalers and retailers.

在受控实验室条件下不同化学防腐剂对非洲菊（Gerbera jamesonii cv. Rosalin）切花采后寿命的影响

目的：本实验旨在评估不同化学防腐剂对非洲菊切花花瓶寿命和质量的影响。研究设计：完全随机设计（CRD）。研究地点和时间：尼泊尔 Nawalparsi（东区）普里特维中学园艺系，2023 年 6 月至 2023 年 9 月。研究方法：八种不同浓度的防腐剂溶液（即 4% 蔗糖、200 ppm 柠檬酸、200 ppm 水杨酸和 1% CaCl2）及其组合，包括对照处理（即仅使用蒸馏水），重复三次。并观察了水溶液吸收、花重、花朵直径、茎弯曲和花瓶寿命等参数。结果研究结果表明，在七种不同的花瓶溶液中，4% 蔗糖 + 200 ppm 柠檬酸的组合在所有观察到的参数上都更胜一筹，被认为是延长非洲菊花瓶寿命和减少采后损失的最有效的花瓶溶液。结论为了提高非洲菊切花的质量，最好使用蔗糖与柠檬酸或 CaCl2 混合处理，因此可以推荐给商业种植者、批发商和零售商。
