Abstract EN

The effect of an arbuscular mycorrhizal fungus ‘‘AMF’’ (Glomus constrictum Trappe) on growth, pigments, and phosphorous content of marigold (Tagetes erecta) plant grown under different levels of drought stress was investigated.

The applied drought stress levels reduced growth vigor (i.e.

plant height, shoot dry weight, flower diameter as well as its fresh and dry weights) of mycorrhizal and non-mycorrhizal plant as compared to control plant (non-drought stressed plant).

The presence of mycorrhizal fungus, however, stimulated all growth parameters of the treated plant comparing to non-mycorrhizal treated plant.

The photosynthetic pigments (carotene in flowers and chlorophylls a and b in leaves) were also stimulated by the mycorrhizal fungi of well-watered as well as of water-stressed plants.

The total pigments of mycorrhizal plants grown under wellwatered conditions were higher than those of non-mycorrhizal ones by 60 %.

In most cases, drought-stressed mycorrhizal plants were significantly better than those of the non-mycorrhizal plants.

So, the overall results suggest that mycorrhizal fungal colonization affects host plant positively on growth, pigments, and phosphorous content, flower quality and thereby alleviates the stress imposed by water with holding.
