| Abstract:
One foliar application of chlorflurenol-methyl-ester ( CFL-m ) at 0.50, 100 ppm and chlormequate chloride ( CCC ) at 0, 2000, 3000 ppm at 6th true leaf stage on winter tomato cv. Pritchard influenced photosynthetic compounds and amino acids assimilation in tomato plants which were affected distinctly in the earlier stages than later ones i.e., CCC treatments increased all determined amino acids while CFL-m had an adverse trend. At flowering stage, amino acids were symmetrically distributed in roots and shoots under different treatments. Crude protein metabolism was positively affected with CCC and CFL-m treatments which was more clear at advanced ages (90 days after transplanting) relative to that the untreated control. Studying carbohydrate fractions, there was no distinct effect for each of the two growth substances on either reducing sugars or sucrose concentrations. Cycocel treatments exerted a profound influence on starch content in tomato plants. | |
