Reproduction of Heterodera zeae and Its Suppression of Corn Plant Growth as Affected by Temperature.


Reproduction of the corn cyst nematode (Heterodera zeae) and its effect on growth of corn (Zea mays) was studied in plant growth chambers at 24, 27, 30, 33, and 36 C. Reproduction of H. zeae increased directly with increase in temperature from 24 to 36 C. Fifteen-cm-d pots of corn seedlings inoculated with a mixture of 5,000 eggs + J2 and maintained for 8… (More)
