the next fall ( Jiang et al., 2011 ). Regardless of daylength, extreme temperatures in summer may restrict the flowering of pitaya ( Nerd et al., 2002 ). Light intensity may affect the nutritional status of shoots and thus influence the number of

intermittent mist (5 s mist every 8 min) and 600-W high-pressure sodium lighting (Gavita, Vancouver, WA; GE Lighting, Cleveland, OH) with a 16-h daylength. For treatment 2, germination mix cold, after seed placement, the trays were lightly covered with clear, 6

photosynthesis and forecasted solar irradiance; thus, the light breaks were not identical between nights. The overall result was a light pattern that was very irregular. Plants are adapted to sense daylength to schedule developmental events to coincide with

have a distinct cultivar-dependent response. Depending on the cultivar, Darrow (1936) and Heide (1977) found higher flower bud numbers with progressively lower temperature under increasingly longer daylengths. In most cultivars, the lower field

Node 14 of Plant 6 in Table 1 did not develop further ( Fig. 3C ), whereas the flower bud on Node 14 of Plant 5 reached blooming ( Table 1 ). Flower bud formation of sacred lotus is independent of daylength. During the growing season from spring to

cultivars of strawberry only flower and bear fruit during specific times of the year as a result of corresponding daylength. This phenomenon is referred to as the photoperiod response. However, certain strawberry cultivars produce flowers and fruit

is paralleled by diapause in the CM population, triggered by shorter daylengths in late summer ( Riedl, 1983 ). CM diapause is perhaps one of the most studied in the Torticidae. Dickson (1949) first demonstrated that larvae entered “a state of

Onions are grown throughout the United States using multiple production systems in a range of climates. Onions are typically divided into short-day, intermediate-day, and long-day types; with bulbing occurring in response to daylengths greater than

significant effect on pigmentation, further experiments were conducted at 23 °C day and 18 °C night for improved plant growth and health. Anthocyanin pigmentation was evaluated under four different light conditions: short daylength, low light intensity (10 h
