EFNEP: Helps low-income families improve diets
by Gaylord P. Whitlock
pp6-8, doi#10.3733/ca.v030n12p6
Abstract
Not available – first paragraph follows: The Expanded Food and Nutrition Education Program (EFNEP) has proved to be a remarkable success in the seven years it has been in operation in California. EFNEP was set up as a joint effort of the federal, state, and county governments to help families acquire knowledge and skills to improve the nutritional quality and adequacy of their diets. The program focuses on families living in poverty or near poverty, especially those with young children.

Damage to fresh tomatoes can be reduced
by Richard F. MaCLeod , Adel A. Kader , Leonard L. Morris
pp10-12, doi#10.3733/ca.v030n12p10
Abstract
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
pp13, doi#10.3733/ca.v030n12p13
Abstract
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.

Abstract
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.
