Legumes are different: Leaf nitrogen, photosynthesis, and water use efficiency.
Using robust, pairwise comparisons and a global dataset, we show that nitrogen concentration per unit leaf mass for nitrogen-fixing plants (N2FP; mainly legumes plus some actinorhizal species) in nonagricultural ecosystems is universally greater (43-100%) than that for other plants (OP). This difference is maintained across Koppen climate zones and growth forms and strongest in the wet tropics ...
متن کاملDifference in leaf water use efficiency/photosynthetic nitrogen use efficiency of Bt-cotton and its conventional peer
This study is to test the effects of Bt gene introduction on the foliar water/nitrogen use efficiency in cotton. We measured leaf stomatal conductance, photosynthetic rate, and transpiration rate under light saturation condition at different stages of a conventional cultivar (zhongmian no. 16) and its counterpart Bt cultivar (zhongmian no. 30) that were cultured on three levels of fertilization...
متن کاملEffects of different irrigation methods and hormone application on water use efficiency, yield, and leaf biochemical traits in potato
Investigation of different irrigation methods on plants is necessary due to limited water resources and the increasing need for food products. The purpose of this study was to evaluate the effect of sprinkler and drip irrigation systems and hormones on morphological and physiological characteristics of potato. Treatments included sprinkler and drip irrigation systems and hormones (gibbere...
متن کاملVariation among Soybean Cultivars in Mesophyll Conductance and Leaf Water Use Efficiency
Improving water use efficiency (WUE) may prove a useful way to adapt crop species to drought. Since the recognition of the importance of mesophyll conductance to CO₂ movement from inside stomatal pores to the sites of photosynthetic carboxylation, there has been interest in how much intraspecific variation in mesophyll conductance (gm) exists, and how such variation may impact leaf WUE within C...
متن کاملMolecular Markers Associated with Water Use Efficiency and Leaf Ash in Soybean
Water use efficiency (WUE) is an important trait that has been associated with drought tolerance of crop plants, and leaf ash (LASH) generally related to WUE. A restriction fragment length polymorphism (RFLP) map was constructed from a soybean [Glycine max (L.) Merr.] population of 120 F4-derived lines from a cross of’Young’ × P1416937. The purpose of this research was to identify quantitative ...
