Available in PDF, EPUB and Kindle. Book excerpt: Seeds of seven hybrid and open pollinated sorghum cultivars were separated with sucrose density solutions into four specific gravity (SG) classes for studies on the effects of seed SG on field performance. The seeds were planted at different densities to provide three levels of competition: "normal" planting density; one high and one low SG seeds in the same hill; and single seeds in widely spaced hills, no competition. There were no differences among the high, medium-low and unseparated (control) seed SG treatments for emergence, vegetative and reproductive development for the normal density plantings. Yield, however, was significantly lower for plants of the unseparated (control) seeds as compared to the SG separated seeds. When high and low SG seeds were planted in the same hill, emergence of the high SG seeds was higher and they produced more vigorous plants that produced more tillers, matured earlier and yielded more as compared to those from low SG seeds. In the case of high and low SG seeds planted at non-competitive spacing, emergence, plant height, number of tillers and yield were higher and the number of days to panicle exsertion and anthesis were fewer for the plants from the high SG seeds as compared to those from the low SG seeds. Priming of high SG seeds did not enhance plant performance above the level of the high SG unprimed seeds. Seed SG was greatly affected by the degreee of weathering and immaturity. As the degree of weathering or immaturity increased, the percentages of seeds in the two highest SG classes sharply declined, while those for the two lowest SG classes sharply increased. Seeds from the intense weathering treatments exhibited cavitation and profuse fungal growth in the placental sac area and in the embryo. Similar cavitation was observed in seeds from the immaturity treatments. Differences in the speed of germination among the unweathered, mature, high SG seeds appeared to be related to differences in permeability of the pericarp to water and/or oxygen.

This book was released on 1975 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two seed characteristics of grain and forage sorghum were studied to determine the extent to which they were associated with viability and vigor. These characteristics were seed size and specific gravity. Fifty seed were obtained from the Mississippi State Seed Testing Laboratory. Twenty-five lots were separated into three size classes designated as large, medium, and small. The other twenty-five lots were separated into three specific gravity cclasses and designated as light, medium, and heavy. The physiological quality of seed from various seed sizes and specific gravity classes of each lot was evaluated for vaibility by the standar germination test and for vigor by the accelerate aging technique and filed emergence response. There was no consistent relationhip between seed size and viability of processed lots of seed. Each seed lot reacted differently, and there was considerable variations among the lots. Specific gravity seemed to be more consistently related to viability in processed lots than was seed size. In general, in each seed lot, an increase in specific gravity of the seed was accompanied by an increase in germination. Accelerated aging technique as a test for seed (capacity to germinate and emerge after being stressed) revelated that seed of the small size and those of light weight were more inferior after accelerated aging than the other size ans weight classes. In general, large, heavy seed gave better responses than did small, light seed. In the field emergence experiment, the relationships (...).

This book was released on 1982 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seed of 36 sorghum (Sorghum bicolor (L.) Moench) geneotypes selected on the basis of high physiological quality were evaluated to determine genotypic differences in response to germination temperatures ranging from 10 to 42C. Seed of high, medium, and low quality were evaluated to investigate seed quality-germination-tempearture relationships. Seed of 24 genotypes were dimensionally sized and permitted to imbile water to evaluate both genotypic variation in speed of water uptake and the influence of seed size on water imbibition. Sorghum seed of near maximum phusiological quality germinated equally well at temperatures between 20 and 30C. Among the range of genotypes evaluated, constant germination temperatures of 14 and 42C were the best for screening genotypes for their to germinate at low and high temperatures, respectively. Two genotypes, IS 1166C and SC 175-14, were equal to or better than all other genotypes at all germination temperatures evaluated. Five genotypes, E 35-1, MN 1958, MN 4508, IS 12685C and TPDXB1388 (9256) were very sensitive to germination temperatures outside the optimal range. Seed of lower physilogical quality were more sensitive to germination temperatures than those of high quality. However, there was a differential response among the genotypes. Regardless of genotype, small seed increased in moisture content more rapidly than large seed when water supply was not limited. Within the same size. there was genotypic varation both in the rate of moisture absorption and the time (...).
