Summary: Genotypes with narrow root cone angle (RCA) are advantageous in water-saving aerobic production (AP) systems, as they allow for deeper water uptake and higher grain yield. Results from glasshouse and field experiments demonstrated the stability and advantages of genotypes with narrow RCA in different water availability conditions, such as longer total root length, cooler canopies, and higher grain yield.

Summary: Stomata play a central role in the hydrological and carbon cycles, with their morphology and physiology affecting the mechanism of stomatal control. Variation in stomatal density among species influences the sensitivity of the stomatal density-[CO2] relationship, impacting the efficacy of inferring palaeo-atmospheric CO2 levels. The interactions between stomatal morphology and physiology are crucial in understanding plant evolutionary history and responses to climate change.

Summary: Drought stress negatively impacted the growth and biochemical content of soybean, but the genotype AGS383 was minimally affected and exhibited superior traits under drought conditions. This genotype showed healthier root and shoot growth, greater leaf area, higher photosynthesis, and better water absorption and potential compared to other genotypes. It also produced lower levels of proline and malondialdehyde. The heavier grains of AGS383 resulted in higher yield under both normal and drought conditions. Further research is needed to identify the genes responsible for AGS383's adaptation to drought stress.

Summary: This study fills the gap in existing research by comparing the effects of biochar and fiber on plant growth, soil water retention, and photochemical responses. Results show that biochar-amended soils significantly increase shoot growth and enhance stomatal conductance of grass leaves during drought periods. In addition, coconut fiber has a higher water retention capacity under low suction conditions.

Summary: The relationship between tree water use and biomass production, as well as the driving factors of transpiration, were studied in young Populus tomentosa trees under different water treatments. Results showed that irrigation significantly increased biomass production with only a small increase in water use, while deficit irrigation resulted in higher biomass production but with higher water consumption. Factors such as vapor pressure deficit and solar radiation were found to be major drivers of transpiration in P. tomentosa trees, while soil water content had minimal effect. These findings contribute to a better understanding of poplar water use characteristics and can aid in developing models for predicting biomass production.

Summary: Accurately estimating crop performance under different fertilizer levels is important for precision agriculture. This study used the gradient boosting regression model combined with two- and three-band spectral indices to estimate sugar beet parameters. The nitrogen levels had the highest impact on most parameters, while the year had a larger impact on sugar content. The parameters, except for sugar content, showed a significant increase with increasing nitrogen levels. Several published and newly developed three-band spectral indices showed a moderate to strong relationship with all parameters.

Summary: Heat stress has a significant impact on plant production, and the response mechanism of evapotranspiration to heat stress is still unclear. This study investigated the effects of heat stress on transpiration and evapotranspiration in gerbera plants. The results showed that transpiration was mainly inhibited at the beginning of heat stress, and the duration and extent of inhibition increased with longer heat stress duration.

Summary: Environments with short growing seasons and variable climates can affect crop growth adversely. This study found that grafting rootstocks can enhance tomato performance under suboptimal soil temperatures, with decreased root hydraulic conductivity and conductance, but increased root-to-shoot ratios. Some commercial rootstocks have traits that maintain better rates of stomatal conductance and shoot N content, contributing to improved plant establishment and performance under suboptimal soil temperatures.
