Summary: Drought is a significant water resources management issue in Iran, especially in Khuzestan Province where water shortage has caused drought. This study utilized precipitation and temperature data, as well as MODIS sensor images, to identify high-risk areas for drought and determine its occurrence. Various statistical techniques were employed to analyze the data, including the calculation of indices and spatial analysis. The findings highlight the severity of drought in southern stations compared to semi-northern and northwestern ones, and certain stations were shown to be at higher risk of drought. Additionally, the study assessed the damage caused by drought, revealing a 50% damage rate for Ahvaz and Abadan stations.

Summary: Southern Chile has seen a rise in sweet cherry production, but climatic differences affect fruit quality and yield. The use of roof covers can protect the fruit, but also have negative impacts. Studies suggest that high levels of antioxidants in the fruit can reduce the incidence of internal browning. Further research is needed on the effects of nitrogen and phosphorus supply on postharvest quality in sweet cherries.

Summary: The KNOX gene plays crucial roles in plant development, and this study identified 19 KNOX gene members in kiwifruit. One of the genes, AcKNOX11, is selectively expressed in flower buds and shoots, and its expression can be induced by ABA and melatonin. Functional analysis revealed that AcKNOX11 delays flowering, reduces plant height, alters leaf shape, and inhibits seed germination through ABA-melatonin interaction.

Summary: Bagging is a crucial cultivation measure that affects the quality of peach fruit by regulating exposure to light. This study investigated the effects of bagging on the content of phenolic compounds in peach fruit and identified the most sensitive compounds to bagging treatment. The study also explored the regulatory role of bagging on phenolic synthetic-related genes. The results showed that bagging affected the accumulation of different phenolics in different peach cultivars and light intensity played a significant role in the accumulation of anthocyanins and other phenolic substances in peach fruit. Additionally, the expression of structural genes and transcription factors related to phenolic synthesis was regulated by bagging and light conditions. These findings provide a foundation for understanding the regulation mechanism of light on the synthesis of phenolic compounds in peach fruit.

Potassium application did not mitigate the negative effects of water stress. There was significant variation among genotypes in terms of leaf and crown traits, and positive interactions between genotype and irrigation were observed. These findings provide insights into the acclimation strategies of cocoa trees and can be useful for selecting drought-tolerant genotypes.
