Photosynthesis and photorespiration in presenescent, senescent, and rejuvenated soybean cotyledons.
Various growth and physiological parameters were measured in germinating, presenescent, and senescing soybean (Glycine max [L.] Merr.) cotyledons and in cotyledons rejuvenated by epicotyl removal 18 days after planting. The maximal measured carbon dioxide exchange rates (CER) in the cotyledons were in the range of those reported for field-grown soybean leaves. Rejuvenated cotyledons accumulated...
متن کاملEffect of Gamma Irradiation on Some Biochemical Parameters and Physico-chemical Properties of Oil in Soybean [Glycine max (L.) Merr.] .
The soybean (Glycine max l. merr) is one of oil seed plants from leguminous family. In this study, the effect of gamma radiation on chlorophyll, soluble and insoluble carbohydrate and composition oil seeds were investigated in soybean. Soybean variety J.K was irradiated with 0,100,200 and 300 gamma ray. The treatment and control seeds planed in with four replicates. The highest amount of total ...
متن کاملHow does elevated CO2 or ozone affect the leaf-area index of soybean when applied independently?
Changes in leaf-area index (LAI) may alter ecosystem productivity in elevated [CO2] or [O3]. By increasing the apparent quantum yield of photosynthesis (phi(c,max)), elevated [CO2] may increase maximum LAI. However, [O3] when elevated independently accelerates senescence and may reduce LAI. Large plots (20 m diameter) of soybean (Glycine max) were exposed to ambient (approx. 370 micromol mol(-1...
متن کاملResponses of field - grown soybean ( cv . Essex ) to elevated S O 2 under two atmospheric CO 2 concentrations Edward
The objective of this research was to determine the effects of elevated concentrations of carbon dioxide (CO2) and sulfur dioxide (SO2) on field-grown soybean. Soybeans (Glycine max L. Merr. cv. "Essex) were grown a full-season in open-top field chambers exposed to either ambient (350 #l L -j) or elevated CO2 (500 #l L -j) levels under two levels of SO2 (0.00 and 0.12 #l L-t). Enriched CO2, wit...
متن کاملOxygen inhibition of photosynthesis and stimulation of photorespiration in soybean leaf cells.
The occurrence of photorespiration in soybean (Glycine max [L.] Merr.) leaf cells was demonstrated by the presence of an O(2)-dependent CO(2) compensation concentration, a nonlinear time course for photosynthetic (14)CO(2) uptake at low CO(2) and high O(2) concentrations, and an O(2) stimulation of glycine and serine synthesis which was reversed by high CO(2) concentration. The compensation con...
