La micorrizazione di alcuni cloni micropropagati di Populus alba L. con Tuber magnatum Pico

Abstract

Mycorrhization of some micropropagated clones of Populus alba L. with Tuber magnatum Pico. - Plants micropropagated from clones of white poplar (Populus alba L.) were mycorrhized with Tuber magnatum Pico using three inoculation techniques: the sporal suspension method, the method of putting mycorrhized root framgments in contact with roots of plants to be mycorrhized and the method of root transmission using mother plants. The mycorrhization methods were then compared. The last two methods gave the best results. An analytical description is reported of the morphological, anatomical and biometrical structures of the mycorrhizae. Some of the clones showed a great capacity to be mycorrhized with the prized white truffle.
