1. When whole plants of Biloxi soy beans are subjected to 8 hour photoperiods, initiation occurs if the intensity of light during the photoperiod is above 100 foot candles. Below 100 foot candles no flower primordia are initiated. 2. When plants are given an 8 hour photoperiod of natural light supplemented by 8 hours of Mazda light, initiation occurs if the intensity of the supplemental light is below 0.5 foot candle, but does not occur if the intensity is above 0.5 foot candle. 3. The stimulus… Expand
Effect of Photoperiod on Development and Metabolism of the Biloxi Soy Bean
TLDR
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
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.

Soybean development as influenced by illuminance during extended daylengths
TLDR
The effects of light level during an extended photoperiod on the ontogenetic development of several soybean genotypes grown under field conditions were characterized and some genotypes showed small or negative responses of lengthened duration of early reproductive development to illuminance. Expand
Photoperiodic influences on the flowering time of the hysteranthous geophyte Sternbergia clusiana population of the Negev Desert Highlands
TLDR
It has been found that in bulbs of the desert hysteranthous geophyte, Colchicum tunicatum, at 15°C, the longer the daylength the earlier the flowering and the higher the percentage of flowering plants. Expand
Reversion of flowering in Glycine Max (Fabaceae).
TLDR
Results indicated that in plants transferred between SDs and LDs, photoperiod can influence organ initiation in florally evoked, but not committed, G. max plants. Expand
The Length of the Photoperiodically Effective Twilight Period
TLDR
In an effort to secure some information on the length of the photoperiodically effective twilight period the writer conducted six series of light intensity measurements, beginning before sunset and continuing until a photronic foot candle meter failed to deflect. Expand
CIRCADIAN RHYTHMIC FLOWERING RESPONSES IN CHENOPODIUM RUBRUM: EFFECTS OF GLUCOSE AND SUCROSE
An endogenous circadian rhythm of flower induction in Chenopodium rubrum that depends on the length of darkness interrupting continuous light has a smaller amplitude and damps out earlier when theExpand
An attempt to analysis of the effect of light on stem elongation and flowering in Hyoscyamus niger L.
TLDR
The shooting of Hyoscyamus niger was studied as a reaction to radiation with coloured or white light in various combinations of intensity and duration, and inhibition by short photoperiods increased with time of radiation as in a formative light action. Expand
Studies on flowering control of dahlia. III.
TLDR
Dahlia is a non-obligate short-day plant in regard to flower initiation and development, and seems to become blind when the photoperiod is changed, within 15 days after budding, to unfavorable day-length shorter than the lower critical one. Expand
La Fioritura Delle Brevidiurne a Notte Continua
TLDR
Experiments showed that plants behave photoperiodically in a quantitative different manner in relation to age degree, and in connection with ontogenetic progress there is a lowering in the minimal anto-inductive number of fotocicli (short day). Expand

Influence of Photoperiods upon the Differentiation of Meristems and the Blossoming of Biloxi Soy Beans
TLDR
Stimulation of two short photoperiods was sufficient to alter the course of development of the growing points in such a way that differentiation of flower primordia resulted, and the time of blossoming of young Biloxi soy beans was influenced. Expand
Locus and Physiology of Photoperiodic Perception in Plants
TLDR
In order to minimize difficulties and at the same time employ contrasted photoperiodic exposure on contiguous parts, plants were grown to a convenient height under vegetative light conditions on opposite sides of a thin, opaque panel having a long, 2-inch horizontal slit. Expand
