The same fact holds good with flowering plants, of which the two main divisions have been founded on characters derived from the embryo,--on the number and position of the embryonic leaves or cotyledons, and on the mode of development of the plumule
Bakhtyary and Hamedy  showed that in studying the effects of salinity stress on kidney beans, increasing salinity resulted to signifisant decreasing effect on rate and percentage of germination and also decreased the vegetative traits such as; radicle and plumule
length, fresh weight of radicle and plumule
, and plumule
A tiny amount of siloxane is then deposited onto each plumule
of down, adhering to its changed molecular structure in a virtually permanent way.
Four different types of explant selected such as, Type A, normal seedling with intact plumule
7) shows that the plumule
is separated from the base of the radicle only by a plate of vascular tissue, called the cotyledonary,, plate by Rao (1971).
Once the yam seed coat ruptures and the radicle (root) and plumule
(shoot) emerge, it cannot return to seed dormancy.
The effect of leachates on seed germination and radicle and plumule
growth was tested by placing 100 seeds (five replications of 20 seeds each) of each test crop in petri dishes (9 cm diameter) containing three layers of Whatman No.
This exercise is introduced with a description of seedling morphology, including root hairs, cotyledons, hypocotyl, epicotyl and plumule
From the position of the impression of the hypocotyl and plumule
on the inner surface of the cotyledon, the notching of the cotyledon margin where the radicle was present before carbonization, and from the reniform shape of the cotyledon (FIGURE 2), one may infer that the specimens represent species of the subfamily Faboideae (Fabaceae), in which typically the embryonic axis is curved and the hilum marginal according to seed length (Delorit & Gunn 1986).
Similarly, Bhatt & Chauhan (2000) found an allelopathic influence of Quercus species on Triticum aestivum, Brassica campestris, and Lens culinaria, whose germination and plumule
and radicle length were suppressed by leaf and bark extracts of all these trees.
Failure of a probed insect to move indicated death, while grains that had lost the plumule
were considered totally damaged.
She provided information on morphology and vascular tissues of the cotyledon, plumule
, and roots, and described briefly the
