WebApr 2, 2024 · Extensive research over the past several decades has revealed that chloroplasts, the photosynthetic organelles of plants, are highly sensitive to heat stress, which affects a variety of photosynthetic processes including chlorophyll biosynthesis, photochemical reactions, electron transport, and CO 2 assimilation. Important … WebJun 4, 2024 · Chlorophyll (Chl) is an important photosynthetic pigment to the plant, largely determining photosynthetic capacity and hence plant growth. However, this concept has not been verified in natural forests, …
Sensitivity and Responses of Chloroplasts to Heat Stress in Plants

WebSalt stress showed prominent effect on all the parameters investigated and there were significant variations between the all weed species. Chlorophyll content, K+, Ca(2+) and Mg(2+) ions in both shoots and roots significantly decreased; while proline and Na+ accumulation significantly increased with increasing salinity up to 40 dS m(-1). WebApr 2, 2024 · Extensive research over the past several decades has revealed that chloroplasts, the photosynthetic organelles of plants, are highly sensitive to heat stress, … WebTable 1: Chlorophyll content in crops under drought stress. Handheld and liquid extracts measurements correspond to SPAD and spectrophotometer unless specified. Interestingly, the chlorophyll a/b ratio decreases during leaf senescence [].Senescence is induced in response to drought and might in turn trigger chlorophyll degradation. launcher hephocraft
