Abstract:
An experiment on “Effect of different Priming treatments on Germination, Growth and Development of Seedlings of China Aster [Callistephus Chinensis (L.) Nees] cv. Phule Ganesh Purple” was conducted at the Centre of Excellence Protected Cultivation & Precision Farming, IGKV, Raipur (C.G), during Rabi (2022-23) season. The experiment was laid out in Completely Randomized Design (CRD) with three replications. There were 15 treatments viz., P₀ (Control non primed seeds), P₁ (Hydropriming Tap water), P₂ (GA₃ 100 ppm), P₃ (GA₃ 200 ppm), P₄ (GA₃ 300 ppm), P₅ (KNO₃ 0.1%), P₆ (KNO₃ 0.5%), P₇ (KNO₃1%), P₈ (CaCl₂ 0.1%), P₉ (CaCl₂ 0.5%), P₁₀ (CaCl₂ 1%), P₁₁ (Trichoderma @ 10 g/Kg seed), P₁₂ (Trichoderma @ 1×10⁵ cfu/ml) P₁₃ (GA₃ 200 ppm ₊ Trichoderma @ 10 g/Kg Seed) and P₁₄ (GA₃ 200 ppm + Trichoderma @ 1×10⁵ cfu/ml). Findings revealed that seed priming with P₃ (GA₃ 200 ppm) performed best in terms of minimum days taken to seed germination (9.06 days) and germination percentage (94.33%) which was statistically at par with P₄ (GA₃ 300 ppm) in terms of minimum days taken to seed germination (11 days) and germination percentage (92.33%).
