Fruit cracking is one of the most important obstacles that pomegranate cultivation suffers from, which inflicts great damage on the crop, sometimes reaching more than 60%. The research was carried out in the 2018-2019 agricultural season in a field planted with pomegranate trees, with the aim of studying the effect of foliar spraying with gibberellic acid in reducing fruit cracking. The experiment was conducted according to a complete randomized block design. We had three treatments for concentrations of gibberellic acid (0, 100, and 200 ppm) and four treatments for the number of spraying times (0, 1, 2, and 3 times). The results showed the superiority of all treatments of spraying with gibberellic acid over the control treatment in most of the studied traits (early flowering and ripening time, increasing the percentage of fruit-set, improving the quality of fruits, increasing productivity). Increasing the number of spraying with gibberellic acid reduced the percentage of fruit cracking, as it reached 73.96%, 24.08%, 13.81%, and 12.98% in treatments of 0, 1, 2 and 3 spraying times respectively. The increase of the spraying concentration also achieved a significant reduction in the percentage of cracking fruits, which amounted to 18.28% and 13.75% in the treatments of concentrations A and B, respectively.
Fruit cracking is one of the most important obstacles facing pomegranate cultivation, which inflicts great damage on the crop, sometimes reaching more than 70%. The research was carried out in the 2018 agricultural season in a field planted with pomegranate trees (French variety) in order to study the effect of foliar spraying with zinc in reducing fruit cracking. The experiment was conducted according to a complete randomized design (CRD). We had three treatments for zinc concentrations (0, 500, 1000 ppm) and four treatments for the number of spraying times (0, 1, 2, and 3 times). The results showed the superiority of all treatments of spraying with zinc over the control treatment in most of the studied traits. Also, increasing the number of spraying times with zinc reduced the percentage of fruit cracking, as the percentage of cracked fruits reached 73.96%, 21.48%, 15.91%, and 12.72% in the treatments of 0, 1, 2, and 3 spraying times respectively. Similarly, the increase in the spraying concentration achieved a significant reduction in the percentage of fruit cracking, which amounted to 17.10% and 14.43% in the treatments of concentrations A and B, respectively.
For protect biodiversity and preserve local genetic types, the research was carried out to evaluate some morphological traits of several locally types from Capsicum annuum Plant (Qarn-Aljamous, Qarn-Alghazal, Haskuria, Long-Mutabasha, Short-Mutabasha, Safrania, and Harimia) of Idlib Governorate in northwestern Syria for the agricultural season 2022. The morphological characterization was carried out by applying 20 qualitative characterizations that included the characteristics of plants, flowers, fruits and seeds. The distinctive qualitative morphological characteristics were the nature of the flower growth, the shape of the fruit, the appearance or absence of the base of the fruit, and the wavy cross-section of the fruit. Morphological characterization results of the studied types, based on some morphological characteristics, showed that there is a difference between these types, especially in the character of the nature of flower growth and fruit traits. The results of the cluster analysis also showed that the studied models were distributed into two groups: the first included (Long-Mutabasha, Short-Mutabasha, Safrania, and Qarn-Aljamous) and the second included (Qarn-Alghazal, Haskuria, and Harmia
