Planta, 1986
Immunofluorescence techniques have been used to study the distribution of calmodulin in several tissues in young etiolated pea (Pisum sativum L.) seedlings. A fairly uniform staining was seen in the nucleoplasm and background cytoplasm of most cell types. Cell walls and nucleoli were not stained.

Supercritical carbon dioxide extraction of wheat plumule oil
Journal of Food Engineering, 1998Abstract Supercritical carbon dioxide was employed to extract wheat plumule oil in this study. Effects of pressure, temperature, CO 2 solvent flows and extraction time on the extraction efficiency were investigated. Three models were set up to describe extraction yield-pressure-temperature, extraction yield-pressure-solvent flows and extraction ...

The Taxonomic Significance of Plumule Morphology in Ceratophyllum (Ceratophyllaceae)
Systematic Botany, 1985The plumule morphology of the species of Ceratophyllum was studied for the purposes of: 1) determining the extent of variability in forking of the first epicotyl leaves, and 2) evaluating plumule features as taxonomic characters by assessing interspecific and intraspecific (interand intrapopulational) variation.

Genetics for speed of plumule emergence in chickpea (Cicer arietinum L.)
Euphytica, 1990Genetics for speed of plumule emergence was studied using six generations (P1, P2, F1, BC1(P1), BC2(P2) and F2) in three crosses. Two of the crosses which had parents of different emergence speed were controlled by two genes with duplicate epistasis. The third cross which involved parents of little difference for speed, indicated incomplete dominance ...

Action spectra for C-glucosylflavone accumulation in Hordeum vulgare plumules
Phytochemistry, 1973Abstract Five-day-old etiolated barley plumules contain the C -glucosylflavones saponarin, lutonarin, and lutonarin 3′-methyl ether. When harvested 24 hr after illumination, increased flavonoid levels were essentially linear with increased energies of monochromatic light at seven wavelengths between 450 and 750 nm.

Vigna unguiculata seed priming is related to redox status of plumule, radicle and cotyledons
Functional Plant Biology, 2019Pre-germination treatments represent the physiological methods that improve plant production by modulating the metabolic activities of germination before the emergence of the radicle. It was suggested that reactive oxygen species (ROS) play a crucial role in signalling seed germination.

Effect of plumule and radicle on somatic embryogenesis in the cultures of ginseng zygotic embryos
Plant Cell, Tissue and Organ Culture, 1996Immature zygotic embryos of ginseng produced somatic embryos on MS medium without growth regulators. However, in the culture of mature zygotic embryos, excision of the embryo was required for somatic embryo induction. Somatic embryos formed only on excised cotyledons without an embryo axis or on excised embryos without the plumule and radicle of the ...

Inheritance of Tolerance to Chilling Stress in Rice during Germination and Plumule Greening
Crop Science, 1998Rice cultivars (Oryza sativa L.) that are adapted to high altitude areas of the sub‐tropics, such as Nepal, have to germinate and rapidly synthesize chlorophyll in the emerging plumule at chilling temperatures. This study was conducted to determine, at the chilling temperature of 17°C, the heritabilities of four traits: germination, the rate of ...

In vitro root induction in hypocotyl and plumule explants of Helianthus annuus
Environmental and Experimental Botany, 1998Abstract The present investigation evaluates the effect of the culture medium, IAA concentration, type of explant and culture period on the in vitro induction of adventitious roots in sunflower ( Helianthus annuus ). To this end, hypocotyls and plumules were cultured for 7 or 14 days on two types of media containing IAA (0.1, 0.3 or 0.9 mg l −1 ...

The Effects of Cow Dung on Plumule Emergence and Seedling Growth of Capsicum Chinense
Plant Science ArchivesCow dung is an abundant and eco-friendly resource for improving soil structure, enhancing nutrient availability and increasing water retention. The present study investigated the effects of varying concentrations of cow dung on plumule emergence and seedling growth of Capsicum chinense.
