چکیده | ||
To study the effect of different concentrations of potassium in the nutrient solution and water stress on the quality and quantity yield of Lilium LA cv.Termoli, a pot experiment was conducted based on completely randomized design in sand and perlite medium (50:50) in three levels of potassium (Kfree, 6 mM K and and 12 mM K in Hoagland solution) with three replications. In the present study, the growth indices, post-harvest life of flower and potassium and chlorophyll contents were measured in shoots. The results showed that the plant dry/fresh weight and vegetative height was highest in 6 mM potassium treatments. Lily postharvest life at 6 mM K was increased 5.7 days relative to k-free conditions. The chlorophyll a, b and total content in nutrient solution without K were lower than in nutrient solution with 6 and 12 mM potassium. | ||
