Abstract

The dragon fruit, has attracted a lot of interest lately due to its eye-catching appearance and exceptional nutritional value. Despite its widespread use, little is known about the ideal circumstances for seed germination and the early stages of growth, such as the length of the seedling shoot, which are critical for the best crop production. By assessing the effects of different growing media on dragon fruit germination and early growth stages, this study seeks to close this gap. The experiment was laid out in the GPB (Genetics & Plant breeding) PG lab, Maxwell block, School of Agriculture (SOAG), ITM University, Gwalior, M.P. during 2024 in Completely Randomized Design with 9 treatments and 4 replications, i.e., T0 (Hydropriming in room temperature at 20-24˚C), T1 (Hydropriming 28˚C), T2 (Sand+ water mixture room temperature 20-24˚C), T3 (Sand+ water mixture in seed germinator 28˚C), T4 (Blotting sheet+ water in room temperature 20-24˚C), T5 (Blotting sheet+ water in seed germinator 28˚C), T6 (Citric acid treatment in room temperature 20-24, T7 (GA3 treatment 100 ppm Seed germinator at 28), T8 (TiO2 NPs 200 ppm Seed germinator at 28 Seeds were sown in petri plates on 26th February, 2024 in seed germinator and room temperature. The highest germination efficiency or percentage with 96.67%, followed by T8 (TiO2 NPs treatment in seed germinator at 28˚C) with 80% and T7 (GA3 treatment in seed germinator at 28˚C) with 78.33%, while T0 (Hydropriming in room temperature at 20-240C) has the lowest germination efficiency or percentage with 8.67%. The significantly highest seedling vigor index was recorded in T6 (Citric acid treatment room temperature at 20-24˚C) with 462.67 followed by T8 (TiO2 NPs treatment in seed germinator at 28˚C) with 353.67 and T7 (GA3 treatment in seed germinator at 28˚C) with 343.57 mg, while lowest seedling vigor index was recorded in T0 (Hydropriming in room temperature at 20-24˚C) with 32.67.

研究各种化学品和不同环境条件对火龙果（Hylocereus undatus var.）

火龙果因其引人注目的外观和特殊的营养价值，最近引起了人们的广泛关注。尽管火龙果被广泛使用，但人们对火龙果种子萌发的理想环境和生长的早期阶段（如幼苗嫩枝的长度）却知之甚少，而这对作物的最佳产量至关重要。本研究通过评估不同生长介质对火龙果发芽和早期生长阶段的影响，试图弥补这一空白。该实验于 2024 年在马萨诸塞州瓜里奥尔 ITM 大学农学院（SOAG）马克斯韦尔楼 GPB（遗传学与植物育种）PG 实验室进行，采用完全随机化设计，共设 9 个处理和 4 次重复，即：T0（火龙果发芽前水压栽培）、T2（火龙果发芽前水压栽培）、T3（火龙果发芽前水压栽培）、T4（火龙果发芽前水压栽培）、T0（室温 20-24 摄氏度下水刺法），T1（室温 28 摄氏度下水刺法），T2（室温 20-24 摄氏度下沙+水混合物），T3（28 摄氏度下种子发芽器中沙+水混合物），T4（室温 20-24 摄氏度下吸水布+水），T5（28 摄氏度下种子发芽器中吸水布+水）、T6（柠檬酸处理，室温 20-24˚C）、T7（GA3 处理，100 ppm，种子发芽器，28˚C）、T8（TiO2 NPs，200 ppm，种子发芽器，28˚C） 2024 年 2 月 26 日，将种子播种在培养皿中的种子发芽器和室温下。发芽率最高，为 96.67%；其次是 T8（TiO2 NPs 处理，种子发芽器温度为 28˚C），发芽率为 80%；T7（GA3 处理，种子发芽器温度为 28˚C），发芽率为 78.33%。幼苗活力指数最高的是 T6（室温 20-24 摄氏度下的柠檬酸处理），为 462.67；其次是 T8（28 摄氏度下种子发芽器中的 TiO2 NPs 处理），为 353.67；再次是 T7（GA3 处理），为 462.67。而 T0（室温 20-24 摄氏度水刺）的幼苗活力指数最低，为 32.67。
