  Maintaining quality and longevity of cut flowers is one of the critical issues in the floriculture industry, especially in cut flowers; and one of the most important problems in chrysanthemum, as one of the most popular cut flowers. Therefore, an experiment was conducted based on completely randomized design as pulse treatment with the three factors: tea extracts with 4 levels (5, 10, 20, and 40 %), 8-hydroxy quinoline sulfate with 4 levels (100, 200, and 400 mg l-1), and rifampicin with 3 levels (100, 200, and 400 mg l-1) on spray chrysanthemum (cv. Purple) with three replications. According to the results, the 20% tea extract treatment and 100 mg l-1 8-hydroxy quinoline sulfate treatment showed the highest vase life, petal protein, total chlorophyll, water absorption, and petal carotenoid. تفاصيل المقالة

  Cold is an environmental factor limiting the growth and yield of agricultural crops. To find cold-tolerant pistachio rootstocks, a factorial experiment was conducted at Pistachio Research Center (PRC), Rafsanjan, Iran during 2017-2018. The factors included six rootstocks (Badami Zarand, Ghazvini, Sarakhs, Integerrima × Badami Zarand, Integerrima × Ghazvini and Integerrima × Sarakhs) and four thermal treatments (4, 0, -2, and -4°C) with three iterations. Seedlings in 6-8 leaf stage were placed in thermal treatments for two hours. Ionic leakage, pH of leaked solution, chlorophyll fluorescence, photosynthesis efficiency index, chlorophyll (a, b, total) and carotenoid contents were the traits assessed in this study. Based on the results, a decrease in temperature made an increase in ionic leakage rate, conversely making decreases in pH of the leaked solution, photosynthetic pigments contents, Fv/Fm and PI index. In addition, the highest photosynthetic pigments, pH of leaked solution, Fv/Fm and PI index were observed in Ghazvini and Integerrima × Ghazvini rootstocks. Meanwhile, the highest ionic leakage was observed in Integerrima × Badami Zarand. In aggregate, Ghazvini and Integerrima × Ghazvini were identified as the most cold-tolerant rootstocks, while Integerrima × Badami Zarand was the most cold-sensitive rootstock. تفاصيل المقالة

  Date palm (Phoenix dactylifera L.) is one of the most important crops for which Iraq is famous. As a result of increased water salinity and the lack of rain in recent years. The technique of magnetizing water has been tried to irrigate palm trees. For the purpose of studying the effect of magnetization on leaf content of some biomarkers. The research was carried out during the years 2019 and 2020, when sixty-three-year-old date palm trees were selected from the variety (Barhi), which are densely textured and planted in the orchard of the tissue date palm station / Ministry of Agriculture located in the desert region of Najaf Governorate. As (well water and river water) were used before and after magnetization by watering the soil around the palm on a weekly basis for sixteen consecutive periods starting from 2/6/2019, results measurements were made for total chlorophyll, total protein, amino acid proline and carbohydrates. The results showed that the magnetization of the water caused significant increases in the leaf content of total chlorophyll, carbohydrates and total protein, and a significant decrease in its content of the amino acid proline. The results indicate that the magnetization of irrigation water increases the efficiency of the palm plant in tolerance saline water and increases its vital properties in the case of irrigation with magnetized river water. These results improve the process of cultivation and management of date palm farms and contribute to increasing production. تفاصيل المقالة
