Abstract

Mycorrhization and application of urban compost for the improvement of survival and growth of Pinus halepensis seedlings under semiarid conditions.

Abstract

Studies were undertaken into the effect of inoculation of Pinus halepensis seedlings with Suillus collinitus and Hebeloma edurum on tree seedling growth (in nursery conditions), and on tree survival and growth following planting of 2-yr-old seedlings (inoculated and non-inoculated) at two sites in Alicante Province, SE Spain (one site on marl, the other on a limestone bed-rock), with or without the application of a compost derived from urban refuse. After two years, mortality of seedlings planted on limestone was higher than that of seedlings on marl, and the compost treatment had no evident effect on survival, although seedlings with compost treatment exhibited better growth. Neither treatment appeared to affect the occurrence of mycorrhizal short roots. Inoculation with mycorrhizas had a relatively small effect on seedling growth.
