Experiments were conducted to evaluate Dendranthema × grandiflorum (Ramat.) Kitamura cv. Bright Golden Anne quality and post-storage growth following storage in the range of 5 to 35C, initial soil water levels (60%, 80%, 100%), and durations (0 to 8 days). Transpiration rate showed a quadratic relationship with storage temperature. Initial soil water content had little effect on transpiration rate in dark storage environments. The lowest transpiration rate was observed in plants stored at 15 or 20C. Amino acid (AA) leakage and post-storage growth were well-correlated. Plants stored at or above 25C became etiolated during storage, while storage at 15C or below did not cause etiolation. Temperatures at or below 15C did not affect subsequent growth rate of chrysanthemum plants. Storage at 20C and above caused a reduction in post-storage growth rate following 2 days of storage.
the additional ecosystem service of storm water removal via transpirational water loss. In this way, water held in the GRS is taken up through the roots and cycled directly back into the atmosphere as water vapor, decreasing the water content of the
., 1998 ). Long-term exposure to high RH decreases the closing ability of stomata because of low foliar abscisic acid (ABA) levels (stomatal malfunctioning). As a result, the capacity of leaves to control water loss decreases when plants are exposed to
no experimental evidence to indicate whether this shelf life extension would be observed if plants experienced severe drought stress. Plant wilting can be caused by a combination of enhanced water loss and inadequate watering, and it is a major
. Where bars are not visible, SE does not exceed the size of the symbol. Water loss is a critical factor in shortening the storage life and increasing deterioration of many fruit during storage ( Ben-Yehoshua, 1989 ; Hardenburg et al., 1986 ). In
described for Expt. 1. Containers were weighed at 24-h intervals for 7 d to determine water loss through the container walls. Because small differences in container dimensions existed, water loss was expressed on the basis of grams per square centimeter of
was used for water loss corrections: [chemical components (fresh weight) × 100 g/9.7 g (snap beans average dry weight) + weight loss during storage (g)]. Snap beans dry weight was determined by drying three weighed aliquots of homogenized snap bean
In two experiments, 16 sweet potato genotypes (Ipomoea batatas L.) were evaluated for drought tolerance using the detached - leaf water loss method as reported by Walker and Miller (1986). Dry weight loss was also determined. Differences in the rate of leaf water loss over a 48 hour period were found.
Vardaman had the greatest amount of dry matter loss and the lowest level of water loss. However, no relationship between dry matter loss and water loss was found.
minimize water loss. Plants can regulate transpiration by increasing leaf stomatal resistance. Under the water deficit environment, plants synthesize a phytohormone, abscisic acid, which triggers stomatal closure to prevent transpirational water loss
. Fresh fruits and vegetables naturally deteriorate after harvest, and the rate of deterioration is affected by a variety of factors, including respiration, ethylene production and action, compositional changes, water loss, physiological disorders, and
