that a temperature of at least 22 °C was required for >90% cranberry seed germination. We hypothesize that openings in the cranberry canopy may induce changes in the local environmental conditions that may be favorable to the germination of cranberry
Abstract
Factors determined to have a pronounced effect on shear-press peak-force values of asparagus, Asparagus officinalis L. included sample size, spear diameter, length of green, and preharvest temperature. Shear-press values were greater following periods of cold weather in early spring. Larger diameter spears had lower peak-force values than smaller spears, indicating that larger spears are more tender than smaller spears. The number and diameter of spears produced by a particular cultivar, and not differences between cultivars, were the characteristics observed to influence shear-press values. Shear-press max peak-force values correlated well with subjective and objective determinations of asparagus fiber.

Lettuce is an important salad crop that is grown year-round in the United States from either direct seeding or transplants. In both cases, lettuce seeds are often exposed to higher than the optimal temperatures, which results in poor and
