Plant Host Selectivity for Multiplication of Glomus mosseae Spore
The study aimed to select plant host for multiplication
of Glomus mosseae spores. Five plant species were used [(corn,
(Zea mays) sorghum, (Sorghum bicolor) lentil, (Lens culinaris),
barley, (Hordeum vulgare) and green bean, (Phaseolus vulgaris)].
Plants were inoculated with Glomus mosseae and grown for 75 days
under glasshouse conditions. Mycorrhizal sporulation and colonization
of all plant hosts were assessed at different sampling periods. At 75
days of growth the highest number of Glomus mosseae spores was
found in mycorrhizosphere of corn plant (167 spore/10 g soil), while the
lowest in the mycorrhizosphere of barley (35 spore/10 g soil). The highest
percentage of root colonization was in corn (76%), while the lowest colonization
was found in green bean (24%). Corn was the most suitable host for spore
production of Glomus mosseae and to extensive root colonization.
It was recorded that plants having more colonization percentage were able
to produce more Glomus mosseae spores. The study indicated that
different plant species significantly influenced the root spore production
and root colonization percentage of Glomus mosseae.
