Here, we examined seasonal variations in leaf photosynthesis, respiration and phenology of Dahurian larch ( Larix gmelinii ) trees that were originated from six provenances and grown in a common garden for 30years; and we partitioned these variations into genetic adaptation and phenotypic acclimation...

The effect of salinity on C 4 photosynthesis was examined in leaves of maize, a NADP-malic enzyme (NADP-ME) type C 4 species. Potted plants with the fourth leaf blade fully developed were treated with 3% NaCl solution for 5d. Under salt treatment, the activities of pyruvate orthophosphate ...
Plants can adjust photosynthesis rates, leaf orientations, or root growth in response to environmental changes, showcasing acclimation. 5 Is adaptation always beneficial? While adaptations improve survival in specific environments, they might not be advantageous if conditions change. 4 What's an example...
Most plant tissues die if their water content falls too low: the nutrients that feed plants are transmitted by water; water is a raw material in the vital process of photosynthesis; and water regulates the temperature of a plant by its ability to absorb heat and because water vapor lost to...
This paper briefly reviews the current developments on the role of leaf hydration on leaf growth and photosynthesis and concludes that changes in growth and stomatal action are not always closely correlated with changes in leaf hydration. A case is developed for soil and root water relations affecti...
The water deficit during these phenological stages reduces leaf photosynthesis and the production of photosynthetic assimilates that are directly transferred to the grain [27]. As a consequence, the number of grains per spike/pod is strongly reduced and so is grain weight, but to a lesser extent...
Other environmental conditions also affect leaf movement, such as temperature, humidity, and nutrient availability. At the cellular level, chloroplasts optimize the capture of light used for photosynthesis by changing their positions within the cell. Under low-light conditions, chloroplasts absorb more ...
