چکیده

As anthropogenic greenhouse gas emissions intensify global climate change, plantations have become an important tool to mitigate atmospheric CO2. Our aim in this study was estimate carbon assimilation and clarify the impact of environmental factors on photosynthesis Zelkova serrata (Thunb.) Makino, plantation species that is extensively planted low altitude regions East Asia. We measured monthly exchange parameters leaf area index assimilation. The results showed significantly affected by vapor pressure deficit temperature, especially dry season, both photosynthetic rate decreased. Lower daytime higher nighttime respiration during which caused a 43% decrease Z. plantations. exhibited lower following planting tropical monsoon area. Therefore, effects extreme weather such as high temperature forest budget could be stronger future. Leaf seasonal variation, severe defoliation typhoon summer. annual estimated at 3.50 Mg C ha?1 year?1

Enhancement of root respiration and photosynthesis in Quercus serrata Thunb. seedlings by long-term aluminum treatment.

In this article, we discuss the effects of long-term (17 months) aluminum (Al) treatment on the growth, root respiration rate, nutrient uptake rate, and photosynthetic activity of two-year-old Quercus serrata Thunb. seedlings. The seedlings were cultivated by supplying a nutrient solution with or without Al twice a week for 17 months in siliceous sand. After 5- and 17-month treatments, growth, ...
