“…With the germination values (GV) (Combination of both germination speed and total germination [Hossain et al, 2005] ) also, seeds influenced with red light irradiation had the highest values (1.87) than seeds with white light (1.33) and seeds without light (0.15) influences. These results conform to previous findings that seed germinations are influenced differently under different light (Colbach, 2002), and that red light spectrum (590 and 680 nm) was most effective in influencing seed germination David and Chawan (1970), and Shyam and David (1975).…”

“…The efficacy observed in red light over white light in respect of percentage germination was similarly reported in past research work where red light was used to promote germination in seeds of Asteracantha longifolia (David and Chawan, 1970) and Cucumis callosus (Bansal and David, 1978).…”

“…On the 3 rd to 4 th day of observation only seeds with red light treatment had three germinated seeds, while there was none with seeds treated with white light and control experiment. The germination rate (GR) was 5.00 with red light influence as against 6.45 with white light, and 12.00 without light, Seeds, just as in vegetative parts of plants, could have varying responses to different light in respect of germination, David and Chawan (1970), and Shyam and David (1975) earlier reported that the region of red light spectrum (590 and 680 μm) was most effective in influencing germination in seeds.…”

Stevia rebaudiana Bertoni is one of 154 members of the genus Stevia and it produces sweet steviol glycosides .It originated from Paraguay. The leaves were used as general sweetening agent. Seed germination in Stevia is generally very low and constituted major obstacle to large scale production of the crop. Different wavelengths from visible light were tested on germination of Stevia seeds. The two lights used were (i) white light -400 to 700nm, and (ii) red light -660nm. Parameters evaluated include (i) Mean time germination, (ii) mean daily germination, (iii) germination rate, (iv) daily germination speed and (v) germination value. Multivariate tests at probability level <.05 revealed that daily germination speed and number of germinated seeds were significantly higher at (< .001) and (< .014) respectively with the effect of red light on seed germination. Red light (660nm) had better influence on germination in Stevia seeds than white light (400-700nm) and control experiment.

“…Promotion of seed germination caused by R light was reported for a great number of plant species and is a phenomenon well established in literature 21 – 23 . For example, germination of Ruellia tuberose L. 24 and Asteracantha longifolia (L.) Nees 25 seeds can be promoted by R light treatment. This promotion can be reversed by a subsequent exposure to FR.…”

Little is known about how light affects seed germination and revegetation of species of thermophilous oak forest. To reveal this relationship effects of white, red, far-red irradiations and dark incubation on germination of eight Potentillo albae-Quercetum taxa were examined. Attempts were also made to evaluate the influence of gibberellic acid and different nitrogen sources on the germination characteristics. Interaction between light and nitrogen was also studied. Freshly matured seeds of all taxa germinated very poorly, indicating presence of primary dormancy. Germination rates increased after wet-stratification treatment and were low in darkness. The highest concentration of the nitrogenous solutions that resulted in high germination level was 10 mM, whereas higher concentrations had a negative effect. Nitrate had the strongest influence which can be proved by a ‘gap detection’ mechanism for gaps in the vegetation. Far-red and red irradiation showed antagonistic effect on seed germination. There was a decrease in germination when far-red was followed by red and an improvement when red was followed by far-red treatment. Under red light, gibberellic acid enhanced germination of positively photoblastic taxa. It was concluded that light factor, associated with vegetation gaps, was the most important signal stimulating germination of the studied taxa.
