“…Ideally, seed should germinate rapidly and give rise to uniform plants. Various treatments, such as water soaking (Chippendale, 1934;Elze, 1949;Kidd and West, 1918), osmotic priming (Guedes and Cantliffe, 1980;Heydecker, 1978;Heydecker and Gibbins, 1978;Khan et al, 1978), and grading (Carvalho et al, 1981;Hunter and Kannenberg, 1972;Lahiri et al, 1982) have improved the seed germination, plant uniformity, and yield of annual crops. One of the most effective techniques to improve citrus seed germination is to remove one or both seedcoats (Cohen, 1956;Monselise, 1959Monselise, , 1962; however, this is not a common practice because it is generally too costly.…”

Commercially processed citrus seeds of Carrizo citrange [Citrus sinensis (L.) Osb. × Poncirus trifoliata (L) Raf.], Swingle citrumelo (C. paradisi Macf. × P. trifoliata), Cleopatra mandarin (C. reticulate Blanco), and sour orange (C. aurantium L.) were used to test the effects of grading, hydrating, and priming on the rate of germination and seedling emergence. Sorting seed into groups by fresh weight or diameter did not generally improve seed performance. Seed fresh weight was highly correlated with maximum seed diameter; also, large seed weight and size were associated with a larger number of embryos. When seedlings from the extra embryos were removed, large seed produced the largest seedlings. Soaking seeds in aerated water significantly increased germination and emergence rates over unsoaked seeds. Soaking at 35C rather than 25C enhanced these differences. Priming seeds in one of three solutions of polyethylene glycol 6000 (—0.6 to—1.2 Mpa) was not successful> as germination and emergence Per centages were lower than in distilled water.

“…Moisture plays an important role in seed germination and emergence. Early in this century, Kidd and West (1918) hydrated bean seeds by soaking them in water. They reported increased germination and growth of soaked broad bean seeds (Vicia faba L.) and increased germination but decreased growth of dwarf beans (Phaseolus vulgaris L.).…”

The effect of moisture content on the emergence and development of `Pinkeye Purple Hull' and MN 13 cowpea [Vigna unguiculata (L.) Walp.] and `Clemson Spineless' okra [Abelmoschus esculentus (L.) Moench] seeds was investigated in a 3-year field study. Moisture content, ranging from 8% to 52%, was obtained by combining seeds, vermiculite, and varying volumes of water in sealed polyethylene packets and incubating them at 22C for 3 days. High moisture promoted the emergence of MN 13, did not significantly affect that of `Pinkeye Purple Hull', and decreased that of `Clemson Spineless' seeds. Percent seed emergence 22 days after planting averaged 17 % for `Clemson Spineless' and 15% for `Pinkeye Purple Hull' seeds, but was 44% for MN 13. High moisture generally promoted early harvest of MN 13 and increased root dry weight but did not affect fresh-pod yield significantly.

“…The nature of the environmental conditions during seed development has long been known to influence the subsequent pattern of germination (Kidd & West, 1918). In agriculture the environment has most frequently been altered by sowing the crop or harvesting its seeds on different dates or by varying the quantities of fertilizer applied to the crop.…”

The influence of genetic and environmental factors on the germination of sugar beet seed

Twenty-four sugar-beet plants were cut into quarters, planted and allowed to produce fruit under varying fertilizer and irrigation treatments. Studies on the germination rates of these clusters showed that there were marked genetic differences between the clones. Wetting the seeds continually by overhead irrigation, to simulate heavy rainfalls markedly decreased the rate of germination, apparently by delaying the onset of maturity. Immature clusters from early harvests of plants which were not irrigated also showed a decreased germination capacity. The fertilizer treatments in this experiment were less important as a source of variation than the clonal and irrigation components. The results may be related to the presence of germination inhibitors in the clusters but there may be important changes in the embryos of the seeds themselves.
