1. Biloxi soybeans were grown in the greenhouse for four to five weeks and transferred to a series of control rooms where various combinations of temperature during the photoperiod and the dark period were applied for five days. Photoperiods of both 8 and 16 hours were used. 2. The effect of these various temperatures on the initiation of flower primordia has been determined. 3. Initiation of flower primordia was influenced to a much greater extent by variation in temperature during the dark… Expand
Effect of Light and Temperature on Floral Initiation in Cocklebur and Biloxi Soybean
In cocklebur, the conditions brought about during the photoperiod may be diminished to such a point that plants fail to initiate floral primordia when subsequently subjected to a 12-hour dark period, and in Biloxi soybean the use of short alternating periods of darkness and light may be a more economical method of maintaining "short-day" plants in a vegetative condition.

Floral Initiation in Biloxi Soybeans as Influenced by Photosynthetic Activity During the Induction Period
Increased concentration of CO2 in natural air resulted in increased floral initiation in Biloxi soybean, and plants that received 2 hours or more of high-intensity light during the photoperiod produced increasingly larger numbers of flower primordia as the duration of high intensity light increased. Expand
Influence of Localized Low Temperature on Biloxi Soybean During Photoperiodic Induction
Petiole-cooling experiments involving plants with two leaves indicate that inhibition of flowering resulted from the influence of low temperature on the transport of a flower-forming stimulus. Expand

Data is given showing the influence of the number of photoinductive cycles to which plants are exposed on the rate of development of flower structures and the photoperiod following a long dark period has a pronounced effect on the initiation and development of flowers. Expand
Effect of Air Temperature on Floral Induction by Short Day in Rice Plants
The effects of floral induction in rice plants as affected by air temperature during short day treatment, using a daylength-sensitive variety "Zuiho", were almost the same as that under constant temperature throughout the both periods. Expand
Photoperiodic Responses of Several Varieties of Soybeans
The initiation of flower primordia in many varieties under continuous light shows that darkness is not a necessary condition for floral initiation in them, and the reactions causing induction are accelerated if the plants are subjected to daily periods of darkness. Expand
Effects of photoperiod and temperature on flowering in mungbean (Vigna radiata (L.) Wilczek)
SummaryForty strains of mungbeans, including all of the entries in the 1st and 2nd International Mungbean Nurseries (IMN), were grown in plant growth chambers in photoperiods of 12, 13, 14, 15, andExpand
Some Effects of Temperature and Photoperiod on the Growth of Tomato Seedlings
Tomato seedlings of the variety San Jose Canner, otherwise maintained at 14⚬ C., were subjected to temperature treatments at 3 ⚬ and 30⚷ C. in the light or in the dark, which resulted in lower dry-weight production and the growth decrease is linear with the length of treatment time. Expand
The effects of temperature, photoperiod and growth regulators on development of Ajuga reptans L.
Growth was greatest at 70F under a 16-hour photoperiod, and those treated with 2000 and 2500 ppm B995 were stimulated by the GA3 to grow especially vigorously, suggesting a synergistic growth stimulation by the two chemicals. Expand
Photoperiodic Flowering Response of Biloxi Soybean in 72-Hour Cycles.
Since Nanda and Hamner have demonstrated a periodic variation in floral response as a function of cycle durations, it was difficult to predict what results might be obtained with various photoperiods given in long cycles of standard duration. Expand


Effect of Photoperiod on Development and Metabolism of the Biloxi Soy Bean
It was found that the longest photoperiod on which fruit formation occurred was 13 hours and the shortest one on which no flowering took place was 16 hours, and the amount of soluble carbohydrates in the transfer groups seems to be correlated with the length ofPhotoperiod. Expand
Effectiveness of Photoperiodic Treatments of Plants of Different Age
In the present investigation the Biloxi soy bean, which is very responsive photoperiodically, was used and critical morphological examinations were made of the fresh material before and after short day treatments. Expand
Photoperiodism in Relation to Hormones as Factors in Floral Initiation and Development
Evidence is presented that the floral initiation substance is not identical with any of the following known plant growth factors: vitamins B1, B2, and B6, ascorbic acid, nicotinic Acid, pantothenic acid), theelin, theelol, inositol, or indoleacetic acid. Expand
Interrelation of Relative Day Length and Temperature
Temperature was found to be a determining factor in influencing the time of flower primordia formation and a marked accumulation of reducing sugars and condensed sugar forms in the low temperature hypocotyl radicles suggests a physiological predetermination influencing the initial stages of growth.
