Summary: This study investigated the relationship between biochemical metabolites such as amino acids and minerals in the receptacle and pistil organs of different apricot cultivars and their effects on frost tolerance. Significant differences in amino acid and mineral contents were found between cultivars and organs, with receptacle organs being less tolerant to spring frost. A negative correlation was observed between CDP values and amino acids and mineral contents, indicating their positive effects on frost tolerance increase.

Summary: This study focused on simulating temperature changes in early spring to understand frost damage in apricot trees, finding that pistils are more cold-tolerant than receptacles in apricot flowers. Organic acids and soluble sugars were found to influence frost tolerance in apricot organs, with receptacles showing more sensitivity to low temperatures than pistils. The data suggests that high levels of sucrose and organic acids contribute to frost tolerance in apricot organs.

Summary: This study investigates the impact of changes in phenology on frost risk for apple trees. The results show that apple budburst and fruit-setting are expected to advance, but at a decreasing rate. The combination of high emission scenarios and distant time periods have a greater impact. While frost frequency is expected to decrease, frost intensity tends to increase. There are regional differences in the changes in frost risk.

Summary: Climate change and its effects on the Earth are significant challenges in the twenty-first century. This study investigates the changes in early fall and late spring frost based on climate change in the Iranian plateau. The results suggest that there will be a delay in the start of early fall frosts and an earlier end to late spring frosts in the future. Additionally, the frequency and period of frost days are projected to decrease.

Summary: This study evaluated frost damages on white spruce seed sources after a late-spring frost, finding that severity was unrelated to seed origin latitude but varied among sites. The proportion of severely damaged trees was highest in the northern site and inversely related to tree height. Recommendations were provided to limit productivity loss from spring climate anomalies.

Summary: This study explores the immediate and carry-over effects of late-spring frost (LSF) and growing season drought on forest ecosystem's functional stability. The results show that both needle-leaf and broadleaf forests are immediately affected by LSF, while needle-leaf forests are more sensitive to drought. Path analysis reveals that the sensitivity of canopy conductance differs between needle-leaf and broadleaf forests, leading to different responses to drought. Furthermore, LSF has a more severe and long-lasting carry-over effect on forests compared to drought.

Summary: This study used ensemble modeling to estimate the changes in apple flowering and fruit-setting, and found that apple phenology stages occurred earlier and the sensitive windows shortened. Although this phenomenon reduced frost frequency in some regions, the increase in frost intensity could offset this alleviation and increase frost risks in other regions. In addition, the climatic risks of poor pollination were lower than late-spring frost risks except for a few regions. The model ensemble provides a realistic assessment for quantifying future risks of late spring frost and poor pollination in apple production systems.

Summary: This study examined the frost ring characteristics of A. chilensis and evaluated the potential for recording spring frosts in central Chile. The age of the trees was found to be a determining factor in the ability to record frost rings, and the exceptional longevity and preservation of the relict wood make A. chilensis frost rings a reliable proxy for monitoring and reconstructing late-spring frost events in central Chile.

Summary: Flower senescence is a complex process involving cytological, physiological, and molecular changes, similar to programmed cell death. Ethylene plays a crucial role in ethylene-dependent petal senescence, triggering various changes such as wilting, oxidative stress, protein and nucleic acid degradation, and autophagy. Despite advances in understanding the mechanism and regulation of petal senescence, there are still knowledge gaps that require critical evaluation of the available literature. A deeper understanding of ethylene-dependent senescence can lead to improved regulation of senescence timing and site, resulting in optimized crop yields, enhanced product quality, and extended longevity.

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: This study revealed that nitrogen deficiency can lead to increased production of reactive oxygen species (ROS) and methylglyoxal (MG), but also enhances the ability of leaves and roots to detoxify these molecules. The effects of nitrogen deficiency on ROS and MG generation and their detoxification systems were found to be different in leaves and roots, with roots being more affected.

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.

Summary: This study investigates the agroclimatic requirements of Prunus species cultivars growing in warm areas using Partial Least Squares regression. The findings reveal that the chilling and heat requirements of the cultivars appear discontinuous, with overlaps or transition periods between the two phases. The warm mean temperatures occurring during the chilling period are the main determinant of the flowering of the studied cultivars.

Summary: This study used Sentinel-2 satellite images to estimate biophysical and biochemical parameters of spinach crops and found that canopy-level parameters were estimated more accurately. The estimation of the canopy-scale parameter AGB using MCARI showed the highest accuracy, while the estimation of the leaf-scale parameter LCC using NDWI showed the lowest accuracy. At the field scale, the validation results for AGB estimation using SR were the best.

Summary: This study investigated the effects of water stress on cocoa trees and found that they are highly sensitive to water stress, with different genotypes exhibiting varied responses. 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.
