Key words: post-harvest period, sainfoin, seeds, laser stimulation, germination
Several studies have assessed the effect of seed colours on dormancy and germination
(Rolston, 1978; Souza, & Marcos-Filho, 2001; Zhang et al.
al in surveying of seed germination
anise(Pimpinellaanisum)under water deficit stresss howed that seed germination
, root and shoot length and seed vigor under stress are decreased.
2004), who showed the allelopathic potential of this species on the germination
and rooting of Sorghum bicolor (sorghum), Raphanus sativus (radish) and Lactuca sativa (lettuce).
Successful establishment of plant species in a natural environment can be related to timing for germination
resulting from seed response to environmental factors such as water availability, light and temperature.
montanus, as in many legumes, given that its germination
improves after the application of pregerminative treatments to soften the seed coat (Rodriguez and Rojo, 1997).
SEVERAL FACTORS influence seed germination
, early seedling growth, and associated stand establishment of warm-season pasture grasses.
There were no germinations
until the third day of incubation, with the highest number of seeds germinating on the fourth day of incubation, followed by a decline to zero on day seven.
By considering that the seed is the marginal product of the plant reform programs and it could be said that the success of a program specifies the time it's seed is in the hand of farmers and is used by them, every type of abnormality in germination
and it's sprouting vigor affects the plant establishment and wastes away the difficulties that the reformers and producers confront.
diversifolia seeds, Campbell and Popenoe (1968) achieved 80% germination
using 350 to 500 mg.
Low molar solutions of gibberellic acid increased the germination
of gamagrass caryopses removed from the cupules, but had only small effects on dormancy when caryopses remained in the cupules (Anderson, 1985; Tian et al.
These compounds are known to modify growth, development of plants, including germination
and early seedling growth.
