Effect of Spraying Salicylic Acid, Some Crop Seed Sprouts and Turmeric Extract on Growth and Vine Nutritional Status of Superior Grapevines

摘要

This study was carried out during 2016 and 2017 seasons to examine the effect of spraying Superior grapevines with rocket and fenugreek seed sprouts and turmeric extract each at 0.05 o 0.2% and salicylic acid (SA) at 100 to 400 ppm on growth and vine nutritional status. The selected vines were sprayed three times with the investigated three plant extracts and salicylic acid at the growth start, just after berry setting, and 21 days after berry setting. Single and combined applications of fenugreek and rocket seed sprouts and turmeric extract at 0.05 to 0.2% and salicylic acid at 100 to 400 ppm caused a material promotion on all growth aspects namely main shoot length, number of leaves/shoot, leaf area, wood ripening coefficient, pruning wood weight and cane thickness and vine nutritional status namely chlorophylls a & b, total carotenoids, N, P, K, Mg, Zn, Fe and Mn in the leaves of Superior grapevines relative to the control. The best materials were rocket seed sprout, salicylic acid, turmeric extract and fenugreek seed sprout, in ascending order. Combined applications (SA at 200 ppm+ fenugreek seed sprout at 0.1%, SA at 200 ppm+ turmeric extract at 0.1% and SA at 200 ppm+ rocket seed sprout at 0.1%) were preferable than using each material alone in this respect. Carrying out three sprays of a mixture of salicylic acid at 200 ppm and fenugreek seed sprout at 0.1% at growth start, just after berry setting and three weeks later was responsible for enhancing growth and vine nutritional status of Superior grapevines.
