Solanum species differ in their degree of frost tolerance and cold acclimation capacity. Cultivated potato species of Solanum tuberosum L. are frost-sensitive, incapable of cold acclimation, and have a maximum freezing tolerance of –3°C. Solanum commersonii Dun is frost-tolerant and can survive to –5ºC pre-acclimation and –10ºC post-acclimation. Breeding attempts...
Different concentrations of various browning inhibitors and a firming agent were evaluated to prevent browning and softening of Bartlett, Bosc and Anjou pear slices during cold storage at 2-4°C. Browning inhibition effect of Semperfresh, Snow Fresh and cysteine were compared with that of 4-hexylresorcinol (4-HR). The effect of ripeness on...
An apparatus was designed to permit freezing tests of
needles and other tissue parts from coniferous trees under
controlled rates of temperature change with time. The design
is based on the principle of a balanced system of refrigeration
demand and heat input to achieve a steady temperature state.
The apparatus...
The effect of frozen storage time on the composition
of the cell wall polysaccharide (CWP) of muskmelon (Cucumis
melo) cultivars at different stages of maturity was investigated.
Changes in composition, firmness, drip loss, and
color of Cantaloupe and Honey Dew melon flesh were determined
at three stages of maturity and...
Anthesis of both staminate and pistillate flowers of Corylus occurs in midwinter. To insure adequate pollination and nut set, these flowers must attain a sufficient hardiness level to withstand low temperatures. This study estimated cold hardiness of Corylus cultivars and species using laboratory freezing of shoots without artificial hardening. In...
