Abstract
The effects of GA3 and some plant extract on fruiting of Barhee date palm grown in Agricultural Research Station farm that located at Kom Omboo, Aswan Governorate, Egypt were investigated during 2020, 2021 and 2022 seasons. All treatments were sprayed three times after two, eight and ten weeks of pollination. The experiment was set up in a complete randomized block design with five replications of one bunch each. The obtained results could be summarized as follow: Fruit retention percentage were significantly decreased due to spray GA3 at 25 or 50, whereas hibiscus or turmeric extract had unsignificant effected compared to unsprayed one (control). Spraying the bunch with GA3 at 25 or 50 ppm gave the highest fruit weight, flesh percentage and dimention of fruits followed sprayed with hibiscus compared to unsprayed ones. All spraying significantly improved the chemical fruit properties in terms of the total soluble solids and sugar contents and significantly decreased the total acidity and total soluble tannins percentages compared to unsprayed ones. No significantly differences were seen due to use 25 or 50 ppm GA as well as 1000 or 2000 of extracts of hibiscus or turmeric extracts. So, it concluded that spray GA3 at 25 or 1000 ppm of hibiscus or turmeric three times after 2, 8 and 10 weeks of pollination to obtain the high yield with good quality of Barhee dates. GA3 reduce the fruit retention and consequently increase the fruit weight and size induce increased the yield. Also, hibiscus or turmeric induced an increase in fruit weight and size then get high yield of Barhee dates. Thus, spraying the bunches of Barhee date palm with 25 ppm GA3 or 1000 ppm hibiscus or turmeric had get the heaviest yield with improvement the physical and tested chemical fruit properties.
