摘要: The first step towards maximising desert truffle production in orchards is to use high-quality mycorrhizal plants. For this purpose, a suitable host plant species should be chosen, taking into account edaphic and bioclimatic conditions and, if possible, it better perennial than an annual one. propagation, photoautotrophic Helianthemum micropropagation system was developed, the normal culture medium composition modified by eliminating sucrose, using perlite instead of agar reducing NH4 +/NO3 – ratio according light intensity. To ascertain most moment for transplantation from vitro ex avoiding losses, probability survival before acclimation process estimated based only on chlorophyll metre SPAD-502 measurement. maximum rate H. almeriense established at 28 units, or its equivalent total content—1.6 mg/g leaf.
