| Popis: |
Growth pouches were used to establish ectomycorrhizae of Pinus strobus using Pisolithus tinctorius as inoculum. An epi-illumination technique was used to follow changes in external morphology of short roots as they became colonized by hyphae and dichotomized. Apices became broader and flatter before an obvious dichotomy was apparent. Secondary dichotomies often formed after the primary dichotomy of the original short roots. Sectioned material showed that a central group of cells in the meristem stopped dividing and became vacuolated as dichotomy was initiated. Two lateral growth centres were established which led to the formation of two apical meristems. |
