cultivars, causing distinct requirements in terms of growth conditions, such as temperature, light, moisture, and nutrients. Temperature is a primary factor that affects plant growth, especially cell growth and elongation, and the process of growth can be

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

seeds within a growing season of ≈170 d and survive in areas that receive average annual minimum winter temperatures of –26 to –29 °C. Trees at the southern extent of the range in Oaxaca, Mexico, may experience no freezing temperature in some years and

planting, but there are few research studies about tarping, and tarping effects on weed dynamics and soil processes are poorly understood. The effects of tillage on weeds are species-specific and dependent on the germination requirements (light, temperature

colorful and/or uniquely shaped scions as potted plants ( Kim and Kim, 2006 ). Erwin (1996) subsequently researched temperature and photoperiod effects on grafted cacti growth to decrease scion losses. Little recent work has focused on desert cacti

Mills (1994) found that as RZTs increased, snapdragons improved their nutrient uptake and growth. Wai and Newman (1992) reported that time to flower for cut flower snapdragon was reduced when RZTs increased even when air temperatures were cool

seedling growth rates vary with temperature. It would, therefore, be interesting to assess the accuracy of degree-days, a common indicator of plant phenology, to predict seedling development ( Bonhomme, 2000 ; Brisson et al., 2003 ; Jones et al., 2003
