We hypothesize: (1) elevated air humidity increases the ratio of non-photosynthetic to photosynthetic tissues, reflected by changes in HVs; (2) the reduction of wood density under high RH-grown trees is associated with biomass distribution among stem, branches, and leaves; and (3) the elevated humidity-driven changes depend on tree size.

2024年4月7日 · Our results show that tree growth increased with high precipitation and high relative humidity. Stem shrinkage was affected mostly by solar radiation, precipitation and vapour pressure deficit during the growing season and was likely caused by tree transpiration.

2019年5月7日 · Plant water status, gas exchange, and 18 O isotopic signatures of the plant were investigated following a typical rainfall pulse and a high-humidity exposure experiment. The results showed that a high content of atmospheric water was the prerequisite for foliar water uptake by H. ammodendron in the arid desert region.

2018年1月30日 · Plants are known to be sensitive to high humidity (low VPD) as indicated by changes in stomatal function, transpiration, mineral nutrient uptake, growth, development, sugar metabolism and leaf epicuticular wax composition in several species and studies.

Increased carbohydrate content in the leaves suggests that sink strength of trees is reduced under elevated humidity. As a consequence of the stress, foliar development is hindered, observed at individual leaf or whole-tree foliage levels, lowering production potential of trees proportionally to their foliar area.

Just as a circle does not fit into a square, a tree originating in a dry and warm place is not suitable for a humid place with a lot of rain. The best thing to have a beautiful garden is to study the climate of the place where we live well and, with these data in mind, choose those plants and trees that are ideal for the climatic conditions.

2019年5月8日 · Plant water status, gas exchange, and 18 O isotopic signatures of the plant were investigated following a typical rainfall pulse and a high-humidity exposure experiment. The results showed that a high content of atmospheric water was the prerequisite for foliar water uptake by H. ammodendron in the arid desert region.

2019年5月30日 · Warm conditions are excellent for the growth of garden staples such as tomatoes and peppers, but when high humidity arrives, it can bring with it a host of other less-desirable visitors, such as molds and mildews. The good news is that a period of hot, dry weather tends to halt or even end some plant diseases brought on by humidity.

2019年9月9日 · Temperature-related increases in air humidity were suggested as an alternative trigger of the spring bud break recently, based on experimental results from nine Eurasian and American tree species, including two needle-leaved trees (Laube et al., 2014b).

2024年6月18日 · Forests are humid due to several factors, including vegetation, transpiration, and evaporation. Vegetation in forests helps moderate surface temperatures and contributes to air moisture through transpiration and evaporation, both of which affect local relative humidity. Why is it more humid in forests?
