Effect of Growth Regulator Brassinolide and Pro-Sol in Some Vegetative Growth Properties and Their Reflection in the Production of Active Nutrients of Catharanthus roseus (L.) G.Don

Abstract

The experiment was carried out in the Lath house of the Faculty of Agriculture / University of Kirkuk for the period during 16/7/2016 to 1/11/2016 to study the effect of spray on the growth regulator of Brassinolide and Pro-Sol in some vegetative growth and its effect on the production of active substances of the Periwinkle Catharanthus roseus(L.) G .Don. The trial included four concentrations of the growth regulator Brassinolide: (0.020, 0.015 0.010, 0.00) ml.l­¹ and four nutrient concentrations of Pr (3.5, 2.5, 1. 0) g .l­¹, the experiment carried out in accordance with the design of full random sectors RCBD and four replications, and the averages were compared by testing L.SD at 5% probability, and the results showed : the spray growth regulator BL concentration .010) ml.l­¹ effect a significant increase in leaf area and a concentration of 0.015 ml.l­¹ in the recipe dry weight, Leaf area nutrient concentration of Pr 1.5 g .l­¹ effect significantly in the dry recipe Leaf area and weight in interference between them showed highest superiority when treated BL2Pr3 in recipe paper space . on the proportion of active substances in the leaves of the plant has a Positive increase in basinolide spray and mineral spray with BL2Pr3 in increased alkaloids active Vincristine and Vindoline gave values of 264.60 and 362.54 μg. Compared with the lowest value of BL0Pr0 with 38.39 μg.¹ in Vindoline, and BL0Pr3 with 40.01 at Fincherstin while BL3Pr3 to increase the active alkaloids (Cathranathine and Vinblastine) had the highest values (409.15),( 432.16) respectively compared with the lowest values in the treatment of BL0Pr0, with values of 52.87 and 41.57 μg respectively for all treatments compared to the root content of the same plant despite the increase in the percentage of active substances .
