| Abstract | ||||
| This experiment was carried out during the two successive seasons of 2021/2022 and 2022/2023 on six-year-old (Prunus persica L.) cv. "Florida prince" is grown in a private orchard located in the Al-Omayed area, Al-Hamam Center, Marsa Matrouh Governorate, Egypt. To elucidate the role of selenium, potassium silicate, proline and humic acid spraying in alleviating the influence of soil salinity on peach cv. Florida prince. All trees of peach trees are irrigated using a drip irrigation system. The experimentation was done on 65 trees (five replicates for each treatment). The experiment was designed as a completely randomized block design, each replicate contained the treatments: control, selenium (Se) at (0.025, 0.05, 0.01 mg/ l), potassium silicate K2SiO3 at (0.05, 1, 2 mg/l), HA at (1, 1.5, 2 g/l), proline at (100, 200, 400 mg/ l). The results indicated that, the humic acid at 2 g/l recorded the highest mean values of vegetative growth were studied (shoot length, diameter, total chlorophyll, leaf area), also, highest mean values of fruit and yield characteristic i.e. (fruit length, diameter, size, weight, yield per tree and per fed. and firmness), chemical fruit characteristics (TSS, TSS/TA, vitamin C, total sugars, reducing sugars, non-reducing sugars, anthocyanin and nitrogen, phosphorus, potassium), followed by treatment of potassium silicate (K2SiO3) at 2 mg/l, selenium at 0.01 mg/l, and proline at 400 mg/l, respectively, as compared to control treatments which recorded the lower man values of this traits, but recorded the higher values of total acidity (TA) as compared to all treatments. | ||||
