In order to clarify the dominant factor responsible for the reduction in photosynthetic rate caused by 1) an increase in leaf-air vapor pressure difference and 2) a decrease in leaf water potential i...
The effect of ambient humidity on the photosynthetic rate of a rice plant population model (area: 120×60 cm, Planting density: about 40 plants/dm2, leaf area index: 6∼7, plant height: about 30 c...
The leaf epidermis of sweet potato, Ipomoea batatus Lam., was peeled to make a direct measurement of photosynthetic rate of mesophyll tissue without stomatal regulation, using the assimilation chamber...
Cyclic changes in the net photosynthetic rate and the transpiration rate were observed in peanut leaves. Both rates changed synchronously with a period of approximately 50 min. The variations in the c...
Measurement of Photosynthetic Rate in Sweet Potato (Ipomoea batatas Lam.) Leaf by Oxygen Electrode Method.
Distinctive Response of Photosynthetic Rate and Water Use Efficiency in Three Soybean Varieties to Waterlogging and Drought-stress.
Characteristics related to photosynthetic rate and leaf area production of 63 mungbean (Vigna radiata (L.) Wilczek) genotypes collected from different Asian countries were evaluated in pot culture con...
The photosynthetic rate and the water content in the rice leaf of potted plant, cv. Yamabiko, Ochikara and Araki, were measured simultaneously by the assimilation chamber method and by β-ray transmitt...
Even though the nitrogen content (mgNdm-2) of rice leaves is the same, a large difference in the net photosynthetic rate (Pn) has been recognized. To determine the reasons for the difference, leaf xyl...
A retrospective analysis of the physiological basis of genetic yield improvement should provide us a direction for future yield improvement. The objectives of the present study were to evaluate the ch...
The effects of supplying reflected light on the photosynthetic rate of middle and lower leaves and on the seed yield of soybean were investigated. Soybean cultivar Suzukari was grown in Wagner pots an...
Effect of Sink-Limitation on Leaf Photosynthetic Rate and Related Characteristics in Soybean Plants.
Invisible injury caused by air pollution is known to make photosynthesis decrease, and thus yields decrease. The purpose of this investigation was to make clear the effects of sulfur dioxide on winter...
Sixteen soybean cultivars of different maturity groups were grown in a field.The photosynthetic rate was measured with terminal leaflets of the 5th and 6th leaves on the main stems at the flowering st...
Two genotypes of kenaf (Hibiscus cannabinus L. : cv. Yuefeng 1 and a National Agriculture Research Center (NARC) strain) were cultivated in 1999 and 2001 to determine and compare growth and morpholog...
