Effects Of Soil Fumigations With Telone And Nemagon On Physio-Chemical And Ultrastructural Changes In Carrot Roots And Sweet Corn Seeds, Maureen Mei-Chu Chen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Carrots (Daucus carota L. cv. Royal Chantenay) and sweet corn (Zea mays L. cv. Iochief) were grown on the Utah State University's Greenville farm in 1969 and 1970. The soil was fumigated with Telone (a mixture of 1, 3-dichloropropene and other chlorinated hydrocarbons) at the rates of 10, 20, and 30 gal/acre and Nemagon (1, 2-dibromo-3-chloropropane) at the rates of 1, 2, and 3 gal/acre one week before planting. Samples of uniformly mature carrot roots were taken for the studies of total carotenes, β-carotene, total and reducing sugars, respiration, and ultrastructural changes; and those of sweet corn seeds for the …
