Glyphosate uncouples gas exchange and chlorophyll fluorescence

growth, leaf gas exchange, and chlorophyll fluorescence responses of two cultivars of salix integra thunb. to waterlogging stress

salix integra thunb. is a shrub distributed in china along the huai river riparian zone, and plays an important role in water and soil conservation. s. integra shrub land is easily submerged during july to october due to the flooding of huai river. in order to characterize the physiological mechanisms of waterlogging tolerance of s. integra and to help rationally select waterlogging-tolerant sp...

Effects of glyphosate on photosynthesis, chlorophyll fluorescence and physicochemical properties of cogongrass (Imperata cylindrical L.)

Cogongrass is one of the most destructive weed in China. It has been reported as one of the ten most troublesome weed species in the world. Therefore, developing an effective method to control this weed has become a significant and worthwhile practice. The effect of glyphosate on this weed growth was investigated during the 2009-2011 years. The photosynthesis, chlorophyll fluorescence, chloroph...

Chlorophyll a + b Content and Chlorophyll Fluorescence in Avocado

Tonnage (T), Simmonds (S) avocado trees, and TxS crosses were evaluated for differences in chlorophyll content and maximal quantum yield of photosystem II in sun and shade-type leaves. Total chlorophyll content by area (Chl a+bar) ranged from 984 mg m in TxS240 to 4320 mg m in Simmonds. Chlorophyll a/b ratio (Chl a/b) ranged from 9.8 to 5.5 in TxS238 and TxS243, respectively. Tonnage and Simmon...

Chlorophyll fluorescence--a practical guide.

Chlorophyll fluorescence analysis has become one of the most powerful and widely used techniques available to plant physiologists and ecophysiologists. This review aims to provide an introduction for the novice into the methodology and applications of chlorophyll fluorescence. After a brief introduction into the theoretical background of the technique, the methodology and some of the technical ...
