SEASONAL CHANGES IN NONSTRUCTURAL CARBOHYDRATES IN CRANBERRY

Nonstructural Carbohydrates in Cool-season Grasses

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...

Seasonal Photosynthesis and Partitioning of Nonstructural Carbohydrates in Leafy Spurge (Euphorbia esula)

Previous evidence indicates that changes in well-defined phases of dormancy in underground adventitious buds of leafy spurge in late summer and autumn are regulated by complex sensing and signaling pathways involving aboveground sugar signals. However, little information exists concerning seasonal photosynthesis and carbohydrate partitioning of leafy spurge, although such information would help...

Seasonal variability of dry matter content and its relationship with shoot growth and nonstructural carbohydrates.

This study assesses how different phases of shoot growth underlie seasonal change in leaf and stem dry matter content (LDMC and SDMC, respectively) of 12 woody Mediterranean species. The relationship between LDMC and nonstructural carbohydrate (NSC) concentrations is also explored and the seasonal vs interspecies variability of LDMC compared. LDMC, SDMC and shoot elongation rate (SER) were meas...

Changes in Soluble Carbohydrates during Seed Storage1

The soluble sugars present in the maize (Zea mays L.) embryo may serve as important components of protection or may contnbute to the deteriorative changes occurring during seed storage. Examination of the changes in sugars during accelerated aging of maize seeds indicates that the decline in vigor is associated with a marked decline in monosaccharides and in raffinose. Sucrose content remains r...
