“…The lowering of chl b could be an indication of chl destruction by excess irradiance under the open field condition (Jason et al 2004). The result suggested that the high chl a to b ratio without significant changes in total chl content could be considered as a protecting mechanism due to the consequence of exposing plants to open field condition (Wang et al 2007). It may be hypothesized that total chl content was high enough to enable the occurrence of high non-photochemical quenching (NPQ) of plants in open field and greenhouse conditions, and this could have facilitated efficient photo fortification of the photosynthetic apparatus against excess irradiation as established in the present study by the photosynthetic recovery observed after the 1400 h ( Fig.…”

“…Because of the difficulty of controlling light intensity [5], researchers have evaluated the effects of shading on morphological characteristics, physiological characteristics, yield, and quality of agricultural crops. Multiple studies [6], [7], [8], [9] have shown that the morphological changes resulting from shading included increases in leaf width, length, and area index, and decreases in leaf thickness due to the reduction of palisade layer number, palisade cells, and spongy parenchyma length.…”

Rice is an important staple crop throughout the world, but environmental stress like low-light conditions can negatively impact crop yield and quality. Using pot experiments and field experiments, we studied the effects of shading on starch pasting viscosity and starch content with six rice varieties for three years, using the Rapid Visco Analyser to measure starch pasting viscosity. Shading at different growth stages and in different rice varieties all affected the starch pasting characteristics of rice. The effects of shading on starch pasting viscosity at middle and later growth stages were greater than those at earlier stages. Shading enhanced breakdown but reduced hold viscosity and setback at tillering-elongation stage. Most pasting parameters changed significantly with shading after elongation stage. Furthermore, the responses of different varieties to shading differed markedly. The change scope of starch pasting viscosity in Dexiang 4103 was rather small after heading, while that in IIyou 498 and Gangyou 906 was small before heading. We observed clear tendencies in peak viscosity, breakdown, and pasting temperature of the five rice varieties with shading in 2010 and 2011. Correlation analysis indicated that the rice amylose content was negatively correlated with breakdown, but was positively correlated with setback. Based on our results, IIyou 498, Gangyou 906, and Dexiang 4103 had higher shade endurance, making these varieties most suitable for high-quality rice cultivation in low-light regions.

“…The chlorophyll a fluorescence determines the state of energy distribution in the thylakoid membrane, the quantum efficiency of photosystem II (PSII) and the extent of photoinhibition (H. Wang, F. Wang, G. Wang, & Majourhat, 2007). Thus, the qualitative and quantitative information about the photosynthetic processes in chloroplasts show the functioning of the photosynthetic apparatus under different internal and external conditions (Roháček & Barták, 1999).…”

Noni is a fruit crop well adapted to different soil and climatic conditions. Aiming to evaluate the physiological responses to salinity, noni seedlings were grown in two levels of NaCl (0 and 100 mM) in nutrient solution and the effects of salt stress on gas exchange, chlorophyll a fluorescence, photosynthetic pigments, relative water content and membrane integrity were assessed after 1, 10, 20, 30 and 40 days of salt stress. The experimental design was a completely randomized in 2 × 5 factorial arrangement with four replications. Salinity did not affect the intrinsic efficiency of water use, but reduced net assimilation of CO 2 , stomatal conductance, transpiration, carboxylation efficiency and contents of chlorophyll a, b, and total carotenoids. Salinity caused no major changes in chlorophyll fluorescence, however the stressed plants showed a decrease in photoprotection capacity by the cycle of xanthophylls. Salinity did not affect the water status of the leaves, but damages to the integrity of the membranes were observed due to duration of salt exposure. The data indicate that noni presents stomatal closure as a mechanism of salinity tolerance, reducing water loss by transpiration and maintaining the water status.
