The Frequency of Vesicular-Arbuscular Mycorrhizae in the Roots of Camellia japonica L. from Different Sites in New Zealand

Abstract

The development of short roots and the frequency of vesicular-arbuscular mycorrhizae in Camellia japonica L. were investigated in different localities in New Zealand. Mycorrhizal short roots were best developed at a depth of 5 to 15 cm. The average number of root hairs per centimeter of root length ranged from 80 to 120. The highest frequency of vesicular-arbuscular mycorrhizae was found in the short roots with diameters of 1.4 to 2.0 mm. Typical vesicular-arbuscular mycorrhizae were found in the short roots of Camellia japonica L. Spores of Endogone occurred in the rhizosphere of mycorrhizal roots.
