Abstract
This study was carried out during the two seasons 2020 and 2021 on five years old "African Rose" plum (Prunus salicina L.) budded on Nemaguard rootstock, grown in a sandy soil under drip irrigation system under El-Nubaria, EL-Beheira Governorate, enhance the fruit size and quality of “African Rose” plums, using at least of these treatments were; T1- Control, T2- 20 ppm TDZ, T3- 30 ppm TDZ, T4- 0.5 ppm Br, T5- 1 ppm Br, T6-0.5% KNO3, T7-1% KNO3, T8-20 ppm TDZ and 0.5 ppm Br, T9- 20 ppm TDZ and 0.5% KNO3, T10- 20 ppm TDZ, 0.5 ppm Br and 0.5% KNO3, T11- 30 ppm TDZ and 1 ppm Br, T12- 30 ppm TDZ and 1% KNO3 and T13- 30 ppm TDZ, 1 ppm Br and 1% KNO3.The experimental design was a randomized complete block design (RCBD) with five replicates. Results indicated that all foliar applications above treatments, significantly (P≤0.05) increased growth characters and number of fruits per tree as compared with the control during both seasons. Also, all treatments, significantly (P≤0.05) increased fruit weight(gm), yield (kg/tree), total yield (ton/feddan), anthocyanin and vitamin C as compared with the control treatment. Moreover, the application of 30 ppm TDZ+1 ppm Br +1% KNO3 and 30 ppm TDZ+ 1 ppm Br treatments, significantly (P≤0.05) increased fruit size, length, diameter and firmness as compared with the others during both seasons. On the other hand, all K- nitrate and 30 ppm TDZ + 1 ppm Br +1% KNO3 treatments, significantly (P≤0.05) increased total soluble solids (%), and total sugars but decreased fruit juice acidity (%) as compared to the control and the rest of the treatments during both seasons.
