In addition to playing a central role in metabolism, soluble sugars such as Glc and Suc help regulate many developmental and physiological processes in plants (for review, see Koch, 1996; Smeekens, 1998; Sheen et al., 1999; Yu, 1999). For example, sugar levels have been postulated to play an important role in determining the time at which some plant species flower. Treatments that induce flower...

Ethylene plays an important role in kiwifruit ripening. However, it is unclear whether there are differences ethylene production different parts of during postharvest Kiwifruit were treated with 0.5 μL L−1 1-MCP for 12 h at 20°C and stored 20 ± 1°C. The results showed the firmness, soluble sugar, total solids (TSS), AcACS1 AcETR2 gene expressions highest core, starch, AcACO2, AcACO3 seedless pu...

damage caused by freezing can be the result of differences in cellular processes, including changes in membrane properties, interactions between macromolecular and enzymatic reactions. in this experiment, total soluble solids (tss) and relative water content of the reproductive buds of cultivars “j. h. hale”, “elberta,” “redhaven, ” “sorkh sefid mashhad” and “amsden” peaches, along with nectari...

seeds deterioration is a natural phenomenon that occurs in all seeds and leading to gradual decline of seed viability during storage. however, the rate at which seeds age depends upon their physiological status, genetic constitution and storage conditions. in the present study we the examined relationship between accumulation of reducing and non-reducing of sugars, soluble protein, the activity...
