| Summary: | and 23% grain moisture contents for the desiccation study and and 45 days after anthesis. At Lubbock germination percent at Lubbock the best harvest date may not have been reached in by their differences in response to desiccation. The first cultivar effects also were significant. Over all cultivars, cultivars, germination remained relatively constant. The cultivars, seed germination remained relatively constant days after anthesis. The different cultivars could be grouped decline in germination percentage. In the third group of diseases, that can cause,deterioration of sorghum seed. experiments were to study effects of chemical desiccation and Field and laboratory experiments were conducted at two fourth group shows a development of dormancy, which can he Germination also increased with increased days after germination percentage tended to increase with a decrease in gradually with decreasing field grain moisture content, group included cultivars with germination that increased harvest after anthesis. The second group reacted the same harvested as early as 50 days post -anthesis. Advantages of harvested at 12 to 15% grain moisture. For the grain harvesting. Three groups could be established by considering implying a gradual release of dormancy. The second group included cultivars with germination that decreased gradually; increased gradually with increase in number of days of increased to a peak at 50 days after anthesis. Implying that indicating accumulation of dormancy. In the third group of like frost, rainfall, and late season insect pests and locations over two years in Texas. Objectives of these maturity study seed were harvested at 30, 35, 40, 45, and 50 moisture content in the grain at time of desiccation. number of days of harvest. Results indicated that at College seed maturity at harvest on sorghum seed germination. seen by the sharp decline of germination with increase in Sorghum plants were desiccated in the field at 35, 30, 25, stages. The first group includes those that germination Station the optimum time for harvesting could be between 35 the cultivars response to harvesting at different maturity the range covered by this study, or that seeds could be this scenario is the avoidance of environmental catastrophes throughout the moisture range of this study. At Lubbock, way of the first group, but seed harvested 45 days started to |
