Arachis paraguariensis, a wild peanut species, is a potential experimental system for studying the molecular mechanisms of flowering in the genus Arachis. The present study was carried out to investigate the effect of photoperiod on in vitro reproductive behavior of five genotypes of A. paraguariensis. Day-lengths of 12, 16 and 24 h were tested to monitor in vitro flowering using growth chambers kept at 26?C ± 1?C and 60% ± 5% relative humidity under an illumination of 40 μmol?m–2?s–1…

Photoperiod Sensitivity of Rhizoma Peanut Germplasm
These studies suggest that selection for late and early season DM production in rhizoma peanut will select for photoperiod insensitivity.
The Effect of Photoperiod on the Reproductive Development of a Photoperiod Sensitive Groundnut (Arachis hypogaea L.) Cv. NC Ac 17090
SUMMARY The physiological basis for responses to daylength of a photoperiod sensitive groundnut genotype (NC Ac 17090) was investigated by comparing its growth and development in natural daylength
In vitro flowering and pod formation from cotyledons of groundnut (Arachis hypogaea L.)
The response of groundnut cotyledons to the presence of various growth regulators in concentrations from 0.1 to 5 mg/l has been studied in detail using several genotypes of ground nut on two different media to study the frequency of flower bud induction.
In vitro gynogenesis in Beta vulgaris L.: Effects of plant growth regulators, temperature, genotypes and season
A pronounced and very significant seasonal effect was observed; the month of June was favoured to that of the other summer months tested and the effect of genotype was significant only for certain media.
Response of Intersubspecific Peanut Hybrids to Photoperiod 1
Three peanut (L.) lines tracing to three geographic areas of South America and representing Valencia, Virginia, and Spanish types and their three F hybrids with reciprocals were evaluated for
In vitro flower induction in roses
With TDZ and ZT as the best choice for flower induction in all six cultivars tested, different rose cultivars varied in their responses to phytohormone treatments.
The Influence of Temperature and Soil Water Deficit on the Development and Morphology of Groundnut (Arachis hypogaea L.)
The rate/temp. relation of several developmental processes in groundnuts was examined in greenhouses maintained at mean air temp. of 19, 22, 25, 28 or 31°C. The sensitivity of the processes to soil
Seasonal culture of dormant reproductive buds ofSalix tetrasperma: Analysis of the flowering process
The flowering process in a female tree ofSalix tetrasperma was analysed by culturing its reproductive buds at different developmental stages during the dormant period on a chemically defined medium
