Damage to fresh tomatoes can be reduced
by Richard F. MaCLeod , Adel A. Kader , Leonard L. Morris
Not available – first paragraph follows: Physical damage, which has a major effect on fruit quality and market loss of fresh market tomatoes, can occur throughout the distribution system between field and consumer. As part of an effort to improve retail quality of fresh tomatoes, studies were conducted to identify the type and amount of physical damage, factors that render fruits more susceptible to injury, and symptom development as related to temperature, storage, and fruit maturity.
Kinetin improves lettuce germination
by Norman C. Welch
Not available – first paragraph follows: Freshly harvested lettuce seeds often fail to germinate under favorable temperature and moisture conditions-a failure called post-harvest or after-ripening dormancy. In most varieties, such dormancy decreases during storage; storage time needed depends on variety, percentage of moisture in seeds, field temperature at seed maturation, and possibly other factors. Post-harvest dormancy can be largely overcome by pre-chilling moist seeds for five days at 12° C.
Early rains alter range forage
by James W. Bartolome
In spite of early rains this year, soil seed reserves of annual range plants are still adequate to establish a stand of forage grasses, but the amounts of the various species will be changed.
