Photosynthetic units of sun and shade plants.
A computer analysis of fluorescence induction curves of leaves treated with 3-(3,4-dichlorophenyl)-1,1 dimethylurea was done for several species. These measurements gave the ratios of the total chlorophyll to photosystem II reaction centers. This communication is a preliminary survey of sun and shade plants and demonstrates a significant variation in this ratio. In the sun plants, the photosynt...
متن کاملWater is allocated differently to chloroplasts in sun and shade leaves.
Hydrogen-1 nuclear magnetic resonance spectroscopy was used to study water allocation in cell compartments of sun and shade leaves. NMR spectra of Acer platanoides were resolved into two peaks that were assigned to chloroplast and nonchloroplast water. Sun leaves contained 1.7 times more water per unit area of surface than shade leaves, and the water was allocated differently. Chloroplasts in s...
متن کاملActivity in Sun and Shade Plants1
The consequences of light adaptation and acclimation of photosynthesis on photosynthetic nitrogen use efficiency (NUE), particularly as it relates to the efficiency of ribulose-1,5-bisphosphate carboxylase (Rubisco) use in photosynthetic CO2 assimilation, was studied in the sun species Glycine max and the shade species Alocasia macrorrhiza. Both G. max and A. macrorrhiza were found to possess t...
متن کاملCO2 Supply during Photosynthesis of Sun and Shade Grown CAM Plants in Relation
Leaves of Kalancho#pinnata were exposed in the dark to air (allowing the fixation of C02 into malic acid) or 2% 02,0% CO2 (preventing malic acid accumulation). They were then exposed to bright light in the presence or absence of external CO2 and light dependent inhibition of photosynthetic properties assessed by changes in 77 K fluorescence from photosystem II (PSII), light response curves and ...
