FOLIAR TOTAL NONSTRUCTURAL CARBOHYDRATES IN APPLE CULTIVAR/ROOTSTOCK COMBINATIONS

Nonstructural Carbohydrates in Cool-season Grasses

Impacts of leaf age and heat stress duration on photosynthetic gas exchange and foliar nonstructural carbohydrates in Coffea arabica

Given future climate predictions of increased temperature, and frequency and intensity of heat waves in the tropics, suitable habitat to grow ecologically, economically, and socially valuable Coffea arabica is severely threatened. We investigated how leaf age and heat stress duration impact recovery from heat stress in C. arabica. Treated plants were heated in a growth chamber at 49°C for 45 or...

16 The Response of Foliar Carbohydrates to Elevated [ CO 2 ]

Accumulation of foliar carbohydrates is one of the most pronounced and universal changes observed in the leaves of C3 plants grown at elevated CO2 concentration (e[CO2]). Carbohydrates are both the product of photosynthetic cells and the substrate for sink metabolism. However, carbohydrates are not just substrates; and the role of carbohydrates in regulation of the expression of many plant gene...

Determination of Total Available Carbohydrates in Plants.

The estimation of carbohydrates plays an important part in both pure and applied plant physiology. While satisfactory methods of extracting and determining the individual types of carbohydrates are available, the complete fractionation of these is a tedious process. Furthermore, for many purposes of a more applied nature the determination of the total available carbohydrate content is of greate...

Seasonal dynamics and age of stemwood nonstructural carbohydrates in temperate forest trees.

Nonstructural carbohydrate reserves support tree metabolism and growth when current photosynthates are insufficient, offering resilience in times of stress. We monitored stemwood nonstructural carbohydrate (starch and sugars) concentrations of the dominant tree species at three sites in the northeastern United States. We estimated the mean age of the starch and sugars in a subset of trees using...
