Assessment of Seed Germination and Growth of Seedling in Different Adenium Hybrids (Adenium arabicum) under Prayagraj Agro-climatic Conditions

The experiment was carried out during May, 2023 to April, 2024 to study the effect of seed germination and seedling growth of different Adenium hybrids in naturally ventilated polyhouse in the Department of Horticulture, SHUATS, Prayagraj. The different hybrids used in the experiment were White Zombie, Green Arabicum, Hulk, Super Dork Dork, RCN, KHZ, PBN, Godji x Red Bangle, Godji F2 and Gc x GT in completely randomized design and each hybrid was replicated thrice. The experimental results revealed that hybrid PBN reported significantly better performance in parameters like germination percentage (100%), days to 50% germination (4.4), seedling vigour index (1813.33), germination speed index (1.15), survival percentage (100%), seedling height (11.07cm), number of leaves per seedlings (16.67), leaf area (15cm2) and caudex diameter (3.93cm) which was found to be at par with hybrid RCN. Hence, hybrids PBN and RCN could be recommended for Prayagraj agro-climatic conditions.
