Abstract
This study was carried out in the greenhouse of the National Research Center, Dokki, Giza, Egypt, in order to investigate the effect of foliar application of boron (0, 300 and 600 ppm B) as boric acid (H3BO3, 17% B) on the yield and yield components and also the seed quality of two sunflower cultivars (Sakha-53 and Giza-102). B application at a rate of 600 ppm produced the highest values of seed yield/plant (g), head diameter (cm), number of seeds/head, weight of 1,000 seed (g), percentage of oil (%) and oil yield/plant (g) of both cultivars. Seed yield/plant increased by 26.85% and 34.81% with increasing B concentration from 300 ppm and 600 ppm as compared to control plants, respectively. The results indicated that application of 300 ppm B resulted in an increase of palmitic, stearic and oleic acids as compared to the treatment with 600 ppm B and control plants. However, the linoleic acid increased gradually with increasing B up to 600 ppm. Such increases were estimated by 8.72% and 7.19% over the control plants or the treatment sprayed with 300 ppm B, respectively. The highest oleic and linoleic acids percentages (52.71% and 36.05%, respectively) were obtained from Sakha-53 cultivar with 300 ppm B foliar application, while the lowest lenolenic acid percentage (2.01%) was obtained at 600 ppm B. The highest content of gluatmine, isoleucine and arginine (9.61, 3.97 and 3.97 mg/100 g dry weight) was obtained from Sakha-53 cultivar, followed by Giza-102 at a rate of 600 ppm foliar application of B. It can be concluded that B plays a vital role for increasing the productivity and quality of sunflower plants, especially when grown under B deficient soil.
