1. 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. The methods employed are the insertion between the photoperiod and the dark period of the photoinductive cycle of a given number of short alternating periods of darkness and light or of a given number of hours of continuous light of low intensity. When Biloxi soybean was treated in the same… Expand
Mechanism of the photoperiodic response of Plantago lanceolata L., a long-day plant.
TLDR
The initial experiments reported in this paper were performed to verify the photoperiodic response of English plantain and indicated that it would respond to long-day treatments. Expand
Influence of Localized Low Temperature on Biloxi Soybean During Photoperiodic Induction
TLDR
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
Effects of some Environmental Factors on Photoperiodic Induction of Beet and Dill
TLDR
Red light of wave lengths greater than 580 μ are capable of inducing the flowering response in dill when used as the sole source of illumination during the induction period, and continuous illumination with 900-1000 foot-candles of light from white fluorescent Mazda lamps, under conditions of only slight temperature fluctuation, was conducive to flowering in beet.

Flowering Responses of Xanthium pensylvanicum to Long Dark Periods.
TLDR
Although the results are inconclusive with respect to a rhythm, they do indicate similarities and differences to the responses of other short-day plants in which rhythms have been demonstrated. Expand
Effect of Darkness and Indoleacetic Acid Following Exposure to Short Day on the Floral Response of Xanthium, a Short-Day Plant
TLDR
It is suggested that the second dark period and the IAA act either to destroy the flowering stimulus or to prevent intermediate reactions in the production of the stimulus. Expand
Interrelations among Effects of Temperature, Photoperiod, and Dark Period on Floral Initiation of Biloxi Soybean
TLDR
The flowering response in Biloxi soybean is apparently influenced to a marked degree by some endogenous rhythm of 24 hours' duration, which might explain the results obtained with cycles of different durations at both normal and low temperatures. Expand
Effect of Nutrition and Age upon Rate of Development of Terminal Staminate Inflorescences of Xanthium pennsylvanicum
TLDR
The data substantiate the theory that the presence of leaf tissue other than that being photoperiodically induced decreases the effectiveness of the flower-promoting stimulus in bringing about floral initiation and the subsequent rate of development of floral primordia. Expand
RHYTHMIC FLOWERING RESPONSES AND PHYTOCHROME CHANGES IN A SELECTION OF CHENOPODIUM RUBRUM
Flowering of Chenopodium rubrum L., selection 374, was examined with respect to an endogenous circadian rhythm, the state of phytochrome, and the result of changing the form of phytochrome during aExpand
Biochemistry of the Photoperiodic Response the High-Intensity-Light Reaction
TLDR
The high-intensity-light process appears to be concerned principally with the production of substrates for respiration and the other processes which take place during an inductive dark period. Expand
In vitro flowering and fruiting of soybean explants
TLDR
A system has been established whereby explants of soybean can be induced to flower in vitro on a hormone-free medium and induction by SD was found to be absolute, although the nutrient status of the parent plants affected the expression of flowering in the explants. Expand

Effect of Variation in Temperature During Photoperiodic Induction Upon Initiation of Flower Primordia in Biloxi Soybean
TLDR
None of the temperature combinations used in these experiments brought about the initiation of flower primordia when photoperiods of 16 hours were used. Expand
Photoperiodic Responses of Several Varieties of Soybeans
TLDR
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
Floral Initiation in Biloxi Soybeans as Influenced by Age and Position of Leaf Receiving Photoperiodic Treatment
TLDR
The capacities of different leaves to supply a flower-forming stimulus is correlated with their relative states of maturity and not with their distances from the growing points where flowers are formed. Expand
Photoperiodism in Relation to Hormones as Factors in Floral Initiation and Development
TLDR
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
Effectiveness of Photoperiodic Treatments of Plants of Different Age
TLDR
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
Localization of Photoperiodic Perception in Helianthus tuberosus
TLDR
In experiments with the Jerusalem artichoke, Helianthus tuberosus L., ZIMMERMAN and HITCHCOCK found that tubers were formed by the plants maintained continuously on conditions of short day, and by those capped with the black bags, but none were formed on the plants exposed to the long days of summer.

Interrelation of Light and Darkness in Photoperiodic Induction
TLDR
Experimental evidence has indicated that in both the soybean and Xanthium photoperiodic induction is dependent in part upon responses which occur as the result of exposure to light, and those owing to darkness as B, and the resultant changes related to A and B may be referred to as C. Expand
