Summary
The infective potential (IP) of nodule homogenates from field-grownHippophaë rhamnoides L. ssp.rhamnoides was determined by counting the number of nodules formed on test plants after inoculation with various dilutions of the homogenates. The IP was almost constant,i.e. 105 to 106 per gram of fresh nodule material. Methods to store nodule material without loss of IP were tested. The IP of air-dried nodule powders stored at 6°C hardly decreased during a period of more than a year.
Data are presented on the IP of soil samples from sites representing various stages of dune formation. BeforeH. rhamnoides appeared, the IP was low: 1 to 36 nodules were formed on test plants per kg of soil. This low IP was due to low numbers of infective endophyte particles in these soils. During the succession of theH. rhamnoides scrub, the IP of the soil increased, due to the increase in the number of endophyte particles in the soil. Gradually, however, nodulation was limited by other environmental factors. The nature of these factors is discussed.
