Also, lower leaves often drop off, growth is hard, and overall quality is not very good. The interaction of temperature and humidity in the grow room is fairly simple - the warmer the temperature, the more water is lost from the plants. The effects were variable and did not occur at all stages of growth. Differences in vapor pressure deficit (VPD) derived from Climate Research Unit . Differences between the japonica and indica varieties in morphophysiological characters under low humidity might cause the varietal differences in the plant growth and dry matter production in rice. The effect of increasing temperature and relative humidity on pollen viability is shown in Fig. Plants use stomata to transpire, or "breathe.". Relatively, dry weight of tops was affected more than root weight and leaf area was affected more than total dry weight, so net assimilation rate decreased with increase in humidity. In the case of Anthurium, good humidity around the plant is even more important than for most other crops, because the plant can only absorb a reduced amount of humidity and hence has less water evaporation than most plants. However, very high or very low relative humidity is not conducive to higher yields of crops. The findings could help in the optimization of high-frequency commercial micropropagation of S. album for year-round production, and supply of this economically prominent vulnerable plant species to the farmers and the industries that rely on it. Growth and development are inuenced by humidity in and around the plant. The humidity is not an independent factor. Sudden increases or decreases of relative humidity-as little as 20%-can cause tissue damage as the plant tries unsuccessfully . Growth and reproduction by powdery mildew pathogens is generally inhibited by decreasing relative humidity. (MERRA-2), was used to provide global PAR to calculate the global LUE by Equation 1. fPAR was derived from the GIMMS3g NDVI dataset.33 Further information on the MPI-GBC, MERRA-2,. Three pieces . increasing the relative humidity from 70 to 90 per cent at 20 C) increased dry weight by 20-30 per cent and sometimes by considerably more. It is suggested that low humidity induced the decrease of water content, which stimulated the loss of chlorophyll (leaf senescence), and high humidity promoted the growth, which results in the delay of the third leafsenescence. One of the major factors affecting raising conditions, relative humidity, has not received much attention even though it is important for animal husbandry.
