Effect of Plant Growth Regulators on Partially Aged Seeds of Spinach (Spinacea oleracea L.) Genotypes

Effect of Growing Media and Seed Treatment on Seed Germination, Seedling Growth, Survival Percentage and Profitability of Seedling Production of Sarpagandha (Rauvolfia serpentina (L), Benth. ex kurz)

“…The external application of GA 3 at higher concentration might have boosted the growth by increasing cell multiplication and cell enlargement ultimately resulting into higher plant growth and physiological efficiency. These results are in agreement with the observations made by Prakash et al, (2017) in Spinach and Randhawa and Negi (1964) in Grapes. : Cocopeat + Vermiculite + Perlite, C 1 : GA 3 @ 50 ppm, C 2 : GA 3 @ 100 ppm, C 3 : GA 3 @ 150 ppm, C 4 : NaCl @ 1%, C 5 : NaCl @ 2%, C 6 : Sulphuric acid scarification, C 7 : Hot water treatment, C 8 : Pre-soaking in tap water, C 9 : Control (without treatment) : Cocopeat + Vermiculite + Perlite, C 1 : GA 3 @ 50 ppm, C 2 : GA 3 @ 100 ppm, C 3 : GA 3 @ 150 ppm, C 4 : NaCl @ 1%, C 5 : NaCl @ 2%, C 6 : Sulphuric acid scarification, C 7 : Hot water treatment, C 8 : Pre-soaking in tap water, C 9 : Control (without treatment) environment facilitate better growth and survival of Sarpagandha seedlings.…”

“…Palaniswamy and Ramamoorthy (1987) in Papaya and Yelure (1992) in custard apple reported increase in growth of seedlings due to application of GA 3 solution. Prakash et al, (2017) reported higher seedling vigour by the application of GA 3 in Spinach. Wagh et al, (1998) reported that seed treatment with GA 3 400 ppm solution prior to sowing was found helpful for increasing root growth in Aonla.…”
