Summary: The study in the eastern Mediterranean region of Turkey evaluated the yield and water productivity response of quinoa to different irrigation methods. The results indicated that regulated deficit irrigation and partial root-zone drying can effectively save water while maintaining quinoa yields compared to full irrigation. Additionally, treatments of rainfed conditions and partial root-zone drying showed significantly higher water productivity values compared to other methods.

Summary: Water availability is a major constraint for crop production, causing conflicts in freshwater allocation. Conventional irrigation is unsustainable due to water depletion, leading to the need for improved water-saving irrigation methods. Partial Root-zone Drying is an effective irrigation technique that saves water but can affect plant root activity.

Summary: Due to climate change, water availability has become a major limiting factor in potato production. This study analyzed the differential response of physiological and yield components in six potato varieties under water deficit conditions and found that Monalisa showed the best response in tuber production under stress conditions. Indirect selection based on parameters associated with water stress can be a useful tool in potato breeding programs for the identification of more tolerant varieties.

Summary: Rice production is the biggest contributor to plant-based carbon emissions globally, particularly in Asia. Introducing sustainable intensification practices or diversifying with lower-emission crops like potatoes is crucial for mitigating climate change. This study analyzed the impact of potato cultivation under zero/minimum-tillage and/or organic mulching on key performance indicators in Asia. The results showed that potato cultivation under these conditions can increase yield, profitability, nutrient-use efficiency, and water productivity, thanks to significant soil moisture conservation.

Summary: This study used the Ledflex fluorometer to measure the effect of water stress on chlorophyll fluorescence in a fescue field under extreme temperature and light conditions. The results showed a significant decrease in fluorescence level under water stress, which was correlated with surface temperature difference. Airflex fluorometer data obtained from an ultralight plane also supported the findings.

Summary: We conducted active and passive measurements of diurnal cycles of chlorophyll fluorescence on potato crops for 26 days. The results showed that variations in chlorophyll fluorescence were directly influenced by changes in irradiance conditions. Under cloudy sky, chlorophyll fluorescence varied in parallel with photosynthetically active radiation (PAR). On clear sky days, a M-shaped diurnal pattern with a minimum around noon was observed. We derived a proxy of fluorescence yield (FYSIF) from spectral transmittance and demonstrated its close relationship with Fs, outperforming other normalization methods.

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.

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.
