Abstract:

This study was carried out with the aim of investigating the effects of prohexadione-calcium (Pro-Ca) application methods on the development and pigmentation of leaves. For this purpose, the methods of application in the form of spraying the leaves of the same number of fries of the same doses with the remaining in the solution containing Pro-Ca at different levels (0, 50, 100 and 200 ppm) equally 140 seeds are compared in terms of fide development and leaf pigmentation parameters.  According to morphological measurements; both Pro-Ca application methods have statistically significantly prevented the development of spices compared to control plants. The lowest; fide length (3.79 cm), body diameter (2.86 mm), body age weight (1.37 g), body dry weight (0.171 g) and root dry weight (0. 096 g) in the waiting of the seed in a solution containing 200 ppm Pro-Ca; the lowest root age weight (1.206 g) was found in the application of the solution containing 100 ppm Pro-Ca in the form of a spray on the leaves. The effect of the application of Pro-Ca in the seed phase on leaf pigmentation was more positively determined, the highest amount of chlorophyll A, chlorophyll B, total amount of chlorophyll and carotenoids was detected in the 50 ppm Pro-Ca dose applied to the seed. As a result, it is recommended to keep the seeds in a solution containing Pro-Ca in a dose of 50 ppm for 18 hours for ideal size control and fide quality.
