Genetic and cytological studies of the necrotic leaf-spot mutation in cotton

Gong, Fangcheng, 1962- January 1991 (has links)
The cotton (Gossypium hirsutum L.) necrotic leaf-spot mutation is due to a single recessive gene. Cytologically the necrotic leaf-spot mutant affects the development and necrosis of leaves associated with the changed staining pattern, contraction and collapse of palisade and spongy parenchyma cells sequentially. The scanning electron microscope revealed that the stomata are also involved or affected by necrosis. The mutation exhibits a slightly deleterious effect on pollen viability, but not on the viability of the embryo.

An evaluation of response to low temperature in several alfalfa populations

Flynn, Mary Ann, 1963- January 1991 (has links)
Yield and quality of nondormant alfalfa (Medicago sativa L.) may be reduced by winter frost. This study surveyed 12 populations for injury and regrowth following artificial frost. Approximately 40 plants per population were grown in a greenhouse for 70 d in styrofoam flats for each of 2 treatments (control and frost) with 4 replications. At 70 d of age, plants were clipped to 4 cm, regrown for 14 d, exposed to 5°C for 5 d to harden, and then exposed to -3°C for 6-8 h. After 2-3 d plants were scored for damage, stem height and stem number. Measurements were repeated weekly for 21 d, including a final damage score. Simulated selection comparing index selection and direct selection demonstrated positive response to selection in all populations analyzed. Selection for growth rate ratio resulted in reduced damage score, while selection for reduced damage did not improve growth rate ratio. Index selection improved both traits. Results indicate that response following frost in alfalfa may be improved.
