Summary
Prunus dulcis (Miller), a tree which is able to develop in low fertility soils, forms VA mycorrhiza. Under glasshouse conditions the growth and P concentration in the leaf tissue of non-mycorrhizal plants, given a customary agronomic dose of P-fertilizer, were lower than those of mycorrhizal plants. The ‘relative mycorrhizal dependency’14 values of the almond tree were higher when a mixture of locally isolated (mainlyGlomus fasciculatus) was used as inoculum. These indigenous endophytes were more tolerant of added fertilizers thanGlomus mosseae taken from the pot-culture collection.
The amount of VA infection and the number of Endogonaceae spores in the rhizosphere of almond trees growing in the field steadily increase from winter (the flowering season of this crop) until summer or early autumn.
