ABSTRACT
The seeds of Kagzi lime were treated for this study with different concentrations of GA3, NAA, Ridomil Gold and control (untreated check). Experiment was conducted during 2013-14 at the Fruit Research Station, Kuthulia, College of Agriculture, Rewa (M.P.) to study seed germination and seedling vigour of kagzi lime (citrus aurantifolia swingle) as influenced by growth regulators and fungicide. Present study comprised eight treatments GA3 @ 10 ppm, IAA @ 50 ppm, Ridomil Gold (2 g/kg seed), GA3 + IAA, GA3 + Ridomil Gold, GA3+ IAA + Ridomil Gold and IAA + Ridomil Gold. The treatment GA3+ IAA+ Ridomil Gold gave maximum germination percentage (84.33) closely followed by IAA+ Ridomil Gold (83%), GA3+IAA (75.67%) and then IAA (74.33%). Accordingly, the treatments like GA3 +IAA+ Ridomil, IAA+ Ridomil, and GA3 +IAA recorded the significantly lower seed mortality (14.00, 15.0% and 23.67% respectively) as compared to the untreated check (37.67%). The maximum root length at 135 DAS stage was recorded with the treatment namely GA3 + IAA + Ridomil Gold (27.63 cm) and IAA +Ridomil Gold (27.51 cm.) while, untreated check recorded lowest root length (17.08 cm). Significantly lower seedling vigour index was recorded with the untreated check (840), Ridomil gold (2007) and IAA (1074).
Key words: Kagzi lime, Growth regulator, Germination, Seedling vigour, Ridomil Gold.
