Summary: This study focused on PSII heterogeneity in two sugarcane cultivars under chilling stress, revealing that chilling stress negatively affects PSII performance, particularly in Guitang 49. The results suggest that PSII heterogeneity can be utilized as a novel technique for evaluating plant responses to environmental stress.

Summary: In a long-term salt-stress experiment, the commercial sweet pepper cultivar showed higher tolerance to the detriment of PSII structure and function compared to the landrace, with the performance index decreasing earlier than the maximum quantum yield of PSII. PSII was more affected than PSI, but PSI functionality recovered in the late phase of the trial.

Summary: This study compared the growth of grafted and non-grafted greenhouse-grown cut rose flowers and found that grafting can improve the photosynthesis rate, transpiration rate, and stomatal conductance, thereby increasing yield. Grafting also improved root activity and resulted in morphological changes such as increased flower size and number of petals.

Summary: Ionizing radiation not only reduces rice yield and causes toxicity, but also poses a threat to human health when consumed. The production and use of freon contribute to the depletion of the ozone layer, which increases the amount of ionizing radiation from the sun affecting rice. This study investigates the response of dry seeds of tetraploid rice to different doses of ionizing radiation during germination, revealing a decrease in water absorption, seed vigor, and GA(3) content. The expression of genes related to alpha-amylase synthesis and gibberellin metabolism is disrupted, and the degree of inhibition increases with higher doses. Further research on the physiological and molecular features of rice germination in response to ionizing radiation is necessary.

Summary: The investigation on the leaf wounding effect on plant physiological procedures and leaf pigments content showed a wide range of responses depending on plant species and severity of the injury. Overall, wounded leaves showed immediate and long-term decrease in gas exchange parameters, while intact leaves exhibited similar profiles with the control ones.

Summary: Research on protein changes under drought conditions and their functional roles is important, but further investigation is needed to reveal the underlying mechanisms.
Recent studies have identified alterations in plant protein abundance in response to drought, and how these changes could impact plant growth and development.

Summary: The effects of low temperatures on the physiological properties and metabolic status of 'Grace Star' sweet cherry trees were studied. The first exposure at lower temperatures caused more changes compared to the second exposure. These findings reveal the impact of low temperatures on sweet cherry trees and its potential negative effect on yield.

Summary: Monoterpenes, emitted by vegetation, have different enantiomers with distinct emission patterns and ecological functions. This study reveals the emission differences of monoterpene enantiomers in response to drought and rewetting, and their impact on cloud formation, contributing to a better understanding of the atmospheric feedbacks to climate change.

Summary: The study found that under 96 kJ/(m²·d) of UV-B radiation, mango trees showed decreased yield, decreased sugar content and vitamin C in fruits, and inhibited photosynthesis in leaves; while under 24 kJ/(m²·d), the content of photosynthetic pigments in leaves increased, but overall performance was similar to the control group.
