EFFECT OF VESICULAR-ARBUSCULAR MYCORRHIZAE ON GROWTH OF IN VITRO PROPAGATED PISTACIA INTEGERRIMA |
| Authors: | A. Schubert, A. Martinelli |
| Abstract:
Plants of Pistacia integerrima were produced by axillary bud culture and transplanted into pots containing a peat-perlite mix, either unfertilized or receiving 74 g kg-1 of a 15–9–15 fertilizer plus micronutrients. At transplant half of the plants were inoculated with both the VAM fungi, Glomus caledonium (Nicol. & Gerd.) Trappe & Gerd. and Glomus occultum Walker. Height and mycorrhizal root colonization were assessed after four months' growth. Roots of inoculated plants were mycorrhizal in both fertilized and unamended substrates; non-inoculated plants were not mycorrhizal, showing absence of VAM propagula in the peat-perlite mix used. The height of mycorrhizal plants in the unamended soil was greater than that of uninoculated controls. In the fertilized soil no significant growth enhancement was observed after VAM inoculation. | |
