“…It is generally known that onion seed is one of the shortest-lived seeds of the common vegetable crops (Duvel, 1905;Pritchard, 1933). As it loses its viability and vigor after harvest more rapidly than seeds of other crops unless special precautions are taken in its storage (Ellis and Roberts, 1977;Voss et al 1999;Amjad and Anjum, 2002;Khan et al 2004).…”

Onion seeds rapidly lose its viability and vigor after short time of harvest, and therefore its germinability largely decline. Consequently, the present investigation was carried out during the period from 2010-2012 in both Plant Tissue Culture Laboratory, Vegetables & Ornamentals Department, Faculty of Agriculture, Mansoura University and greenhouse of a private nursery in production of vegetable transplants, Qlabasho village, El-Dakahlia Governorate to study the effect of Moist-chilling (cold stratification) treatment for four periods (0, 5, 10 and 15 days) at 5 ± 1 0 C on improvement of the germination parameters in the laboratory (germination percentage, seedling length, fresh and dry weight and vigor index) of onion seeds cv. "Red Beheri" stored for one or two years and enhancing growth characters (bulblet diameter, transplant length, fresh and dry weights and vigor index) of the subsequent transplants. The obtained results clearly indicated that all germination parameters of onion seeds stored for one or two years (except mean germination time) and also all obtained transplant characters except leaves number were significantly increased in all moist-chilling treatments than control one. The best treatment in this regard was moist-chilling for 15 days whereas the lowest one was control (non chilled seeds).

“…Longevity between and within species.-The results of numerous experiments (Duvel, 1905;Beal, 1911;Dorph-Petersen, 1925;Goss, 1939;Kjaer, 1940;Darlington, 1951;Muenscher, 1955) indicate wide differences among species as to retention of viability in buried seed. Wide differences also occur among seeds of the same species or lot of seed.…”

The Eighty‐year Period for Dr. Beal's Seed Viability Experiment

Darlington, H. T., and G. P. Steinbauer. (Michigan State U., East Lansing.) The eighty‐year period for Dr. Beal's seed viability experiment. Amer. Jour. Bot. 48 (4): 321–325. 1961.—Seeds of 20 species of plants were buried 80 years ago on the Michigan State University campus. Bottles have been dug up periodically in the intervening years and the seeds tested for viability. A bottle representing the 80‐year period of burial was dug up this spring and the contents distributed uniformly on the surface of sterilized soil in the greenhouse. Of the 20 species whose seeds were buried in 1879, only 3 have survivors as viable seeds. These are the same 3 that had survived the 70‐year burial period, namely: curled dock, Rumex crispus; evening primrose, Oenothera biennis; and moth mullein, Verbascum blattaria. The low percentage survival of curled dock (2%) indicates that the longevity of the buried seeds of this species is nearing the end. The situation is more favorable for evening primrose, with 10% survival. The third, moth mullein, has about as many survivors as 10 years ago, a remarkably high figure of 70% viability. Since there has been no significant drop in viability of the buried seeds over the last 30 years, it seems highly probable that longevity of buried seeds of this species may extend over a century. A brief summary is given of the current status of the behavior of buried seeds, based on this and other buried seed experiments.

“…Whereas the only germination of common ragweed seeds in Beal's experiment was after 40 years of burial, seeds of common ragweed in Duvel's experiment germinated, without special treatment, after being buried for 1, 3, 6, 10, 16, 21, and 30 years (Duvel, 1905;Goss, 1924;Toole, 1946). In Duvel's experiment, in contrast to Beal's, the seeds were exhumed and tested for germination in " November" 1903(Duvel, 1905, "in the fall, usually just before the ground froze" in 1905froze" in , 1908froze" in , 1912froze" in , and 1918froze" in (Goss, 1924, in "early spring" 1923 (Goss, 1924), and 4 May 1932 (Toole, 1946) when some of the seeds were nondormant. In the last germination test in the Duvel experiment, seeds were exhumed in early autumn (11 October 1941 ), after 39 years of burial.…”

“…The presence of these hulls probably meant that some seeds had germinated and that the seedlings had decayed during the first 5 years of burial. Although light is required for germination of many seeds in a ragweed seed population, a portion of the seed population does not require light for germination and will germinate while they are buried (Willemsen, 1975b;Baskin and Baskin, unpubl. It is interesting to compare the germination results for common ragweed seeds in Beal's experiment with those from the buried viable seed experiment started by Dr. J. W. T. Duvel in 1902(Duvel, 1903. Whereas the only germination of common ragweed seeds in Beal's experiment was after 40 years of burial, seeds of common ragweed in Duvel's experiment germinated, without special treatment, after being buried for 1, 3, 6, 10, 16, 21, and 30 years (Duvel, 1905;Goss, 1924;Toole, 1946).…”

Dormancy and Germination in Seeds of Common Ragweed With Reference to Beal's Buried Seed Experiment

Baskin

1977

American J of Botany

View full text Add to dashboard Cite

Common ragweed (Ambrosia artemisiifolia L.) was one of 19 herbaceous weedy species used by Beal in his buried viable seed experiment started in 1879. No seeds germinated during the first 35 years of the experiment when germination tests were performed in late spring, summer or early autumn. Germination did occur in seeds buried for 40 years when seeds were exhumed and tested for germination in early spring. Data obtained in more recent research provide the probable explanation for these results. Seeds of common ragweed that do not germinate in spring enter secondary dormancy by mid to late spring and will not germinate until dormancy is broken the following late autumn and winter. Thus, during the first 35 years of the experiment seeds were dormant when tested for germination, whereas seeds buried for 40 years were nondormant. Seeds buried 50 years or longer did not germinate when tested in spring, probably because they had lost viability and/or seeds germinated during burial and seedlings died.
