Summary: European earwigs may have a significant economic impact on sweet cherry production, with the severity of the impact varying between cherry varieties and influenced by factors such as bunch size. However, the reasons for the differences in damage between varieties remain unknown and require further investigation to minimize the impact of earwigs on sweet cherry production.

Summary: Intensive K foliar applications can enhance the firmness and acidity of sweet cherry fruits grown under plastic covers, reducing fruit cracking and pitting while affecting condition defects. However, the effects may significantly vary depending on season and locality.

Summary: This study found that under full waterlogging conditions, both fine root growth and transpiration of Pinus thunbergii significantly decreased, while under partial waterlogging conditions, fine root growth increased significantly in the non-waterlogged top soil. After 8 weeks of waterlogging, transpiration recovered to no significant difference compared to the control group, mainly attributed to the increase in fine root growth in the non-waterlogged top soil.

Summary: This study evaluated investment decisions in sweet cherry production systems in central Chile using Decision Analysis. The results showed that covering orchards in southern-central Chile could bring significant benefits, while the effectiveness was not significant in northern-central areas.

Summary: Chile, the world's largest exporter of sweet cherries, is facing challenges in establishing orchards in acidic volcanic soils due to aluminum phytotoxicity. Research shows that increasing soil aluminum concentrations negatively impact nutrient uptake and growth of sweet cherry trees, particularly in the second season. Addressing soil acidity is crucial for successful establishment of sweet cherry orchards in southern Chile.

Summary: This study reveals the physiological, anatomical, metabolic, and transcriptomic impact of boron on early fruit growth and development in sweet cherry. Boron application during pre-flowering stage increased endogenous boron content, promoted fruit set and mesocarp cell enlargement, and led to accumulation of various sugars, alcohols, organic acids, and amino acids at different developmental stages. Transcriptomic analysis identified boron-responsive genes mainly involved in secondary metabolism, amino acid metabolism, calcium-binding, ribosome biogenesis, sugar homeostasis, and photosynthesis.

Summary: This study investigated the distribution and dynamics of cotton fine roots under film-mulched drip irrigation using the minirhizotron technique. The non-uniform distribution of soil moisture and salinity affected the distribution of root length density (RLD). The average RLD in the shallow soil layer decreased due to localized salinity accumulation. A high RLD peak was observed in the 95-100 cm soil layer with high soil moisture content. The production and number of new roots were highest during the initial growth stages. Thinner roots in the deep soil had shorter lifespans than those in shallow soil. The minirhizotron technique was found to be reliable for estimating cotton fine root distribution and dynamics under film-mulched drip irrigation. A cotton root system architecture model could be developed based on these observations for more accurate evaluation of root distribution and dynamics.

Summary: In soils with low air content, rootstocks like 'Colt' and 'Maxma 60' showed increased fine root production and were classified as tolerant, while rootstocks like 'Mazzard F12/1' and 'Gisela 6' showed reduced growth and photosynthesis rates, leading to classification as sensitive rootstocks.

Summary: Boron is an essential element for plants, but its availability needs to be carefully managed as both low and toxic concentrations can have adverse effects on crop production. This study investigated the response of cherry trees to different concentrations of boron in the soil, and found that adequate levels of boron promote better growth, biomass, photosynthesis, and visual appearance, while toxic levels lead to abnormal morphology and growth.

Summary: The study evaluated the effects of controlled irrigation on sweet cherry trees in covered and open field conditions. Trees under high tunnels showed higher soil matric potential, midday stem water potential, and stomatal conductance. In contrast, reducing irrigation in open field conditions resulted in poorer tree water status, affecting plant growth and fruit size. Additionally, cherry trees under high tunnels bloomed 7 days earlier and were harvested 10 days earlier compared to those in open fields.

Summary: Leaf size and number varied between different cultivar/rootstock combinations and training systems, with a model explaining 72% of the data variability through two principal components. Relevant indicators for the first component were leaf weight per hectare and leaf area index, showing a significant training system effect, while for the second component they were leaf weight per leaf area and production per leaf area, mainly for productive efficiency.

Summary: It has been shown that hormones play a key role in the establishment, maintenance, and release of bud dormancy in temperate trees. The ABA pathway plays a central role in controlling dormancy progression.

Summary: The study revealed that the spatial distribution of roots of Mongolian pine trees changes with age, with older trees occupying a larger space horizontally and vertically. This information can be used to optimize stand density in plantations to avoid dieback or mortality due to water competition, providing new insights into plantation management in semi-arid and arid sandy regions.

Summary: The study evaluates the main adaptive mechanisms developed by young sweet cherry trees to cope with drought, including important stomatal regulation, reduced vegetative growth, and decreased leaf turgor potential. The trees showed occasional osmotic adjustment during drought, but it was not enough to maintain normal growth. Severe water stress led to early defoliation as a water conservation measure.

Summary: Increasing ozone and nitrogen addition had contradictory effects on plant photosynthesis and growth. This study investigated the effects of ozone alone and in combination with nitrogen addition on root production and fine root respiration of poplar. The results suggest that changed relationships of plant fine root traits under global changes should be considered to accurately project future carbon cycle.
