Conidial germination in Claviceps fusiformis Lov. in relation to physical and ontogenic factors

O. P. Verma, V. N. Pathak


Influence of certain physical and ontogenic factors on germination of conidiu of Clariceps fusiformls Lov., the incitant of pe rl miller (Pennisetum americanum (L.) Leeke) ergot. was investigated. Maximum germination of conidia was recorded at 24 C and l0% RH. The germination was completely checked in washed conidia. Increasing dilution of honeydew with sterile water as well as drying of conidia for more than 30 minutes caused significant reduction in their germination. Conidia up to the age of 3 days gave significantly more germination than older conidia.
