Adzuki bean, a typical short-day plant
(SDP) has high value of pharmaceutical and health care.
Cilantro is a short-day plant
that needs cool weather.
For example, it is possible to take a short-day plant
such as cocklebur (Xanthium) and place it under long-day conditions so that the plant remains entirely vegetative.
Studies with the long-day plant Sinapis alba and the short-day plant
Xanthium strumarium L.
Of the many papers published concerning the physiological effects of prostaglandins in plants, the most extensive was the study of the possible involvement of PGs in the flowering of the short-day plant
(SDP) Pharbitis nil (Groenewald & Visser, 1974).
Even though soybean is generally a short-day plant
, the early maturing and photoperiodically sensitive cultivars have longer critical photoperiods than later maturing cultivars (Borthwick and Parker, 1938, 1939).
In soybean, a short-day plant
, genetic control of flowering and maturity has been well documented with the identification and description of genes which delay flowering under extended photoperiods (Bernard, 1971; Buzzell, 1971; Saindon et al., 1989; McBlain and Bernard, 1987; Cober and Voldeng, 2001).
Cooper (1960), citing the work of Benedict (1940) and Gardner and Loomis (1953), listed switchgrass as a short-day plant
with no vernalization requirement.
In the short-day plant
rice, regarded as a model monocot species, conventional genetic analyses of flowering time (heading time) have been extensively conducted; consequently, as many as 23 heading-time loci have been identified (Yokoo and Kikuchi, 1992; Tsai 1986; Poonyarit et al., 1989; Okumoto and Tanisaka, 1997; Ichitani et al., 1998).
Lin (2000) reviewed the role of phyB in delaying flowering in Arabidopsis and pea (Pisum sativum L.), both long-day plants, and in sorghum [Sorghum bicolor (L.) Moench], a short-day plant
. Lin (2000) concluded that phyB inhibition of flowering was more apparent in noninductive photoperiods for both short- and long-day plants.
