Initiation of Floral Primordia in Cestrum diurnum and Cestrum nocturnum in Response to Various Photoperiodic Patterns.
Information concerning the plhotoperio(lic response of Cestrum isocturnums L. was initially reported by Sachs (4). From his investigation he found it was a long-short day (LSD) plant and, under experimental conditions he used, did not produce floral primordia in response to other light patterns. More recent work with C. niocturnunti confirmed the previously reported LSD response but added that ...
متن کاملInheritance of Factors Affecting Floral Primordia Initiation in Cestrum; Hybrids of C. elegans and C. nocturnum.
Photoperiod patterns of hybrids of Cestrum elegans (Brongn.) Schlect., a day neutral plant, and C. nocturnum L., a long-short day and long day plant, were investigated. Plants of the F(1) generation, F(2) generation, and backcrosses to each parent were tested on short day, long day, continuous light, long-short day and short-long day for floral primordia initiation. The data recorded suggest 2 ...
متن کاملUrine screening in outdoor volunteers: day versus night versus 24 hour collection.
Urine constituents were measured in 12 healthy outdoor volunteers on four occasions within a month. Day, night, and 24 hour collection periods were compared. Measurements made on the four occasions did not differ. The amount of water, creatinine, electrolytes, proteins, and enzymes were higher during the day (up to three fold, p always less than 0.05), while equal amounts of amino acids were ex...
متن کاملThe C4 Model Grass Setaria Is a Short Day Plant with Secondary Long Day Genetic Regulation
The effect of photoperiod (day:night ratio) on flowering time was investigated in the wild species, Setaria viridis, and in a set of recombinant inbred lines (RILs) derived from a cross between foxtail millet (S. italica) and its wild ancestor green foxtail (S. viridis). Photoperiods totaled 24 h, with three trials of 8:16, 12:12 and 16:8 light:dark hour regimes for the RIL population, and thes...
متن کاملFloral Induction in a Short-Day Plant, Plumbago indica L., by 2-Chloroethanephosphonic Acid.
Whereas long-day species can be brought to flower under non-inductive conditions by the application of chemicals such as gibberellic acid (see review by Lang, 1965), short-day species have been refractory so far to chemical induction. The outstanding exception is the pineapple (Ananassa sativa L.) which can be forced to flower by applications of ethylene and compounds releasing ethylene such as...
