Abstract
The aim of the experiment was to study how Glomus mosseae influences the growth and flowering of cacti such as Mammillaria laui and Chamaecereus sylvestrii. The experimental theses have been: (1) soil inoculated with Glomus mosseae and fertilized; (2) soil without Glomus mosseae, irrigated with water and fertilizer (control). The test showed a significant increase in the agronomic parameters analysed in plants treated with Glomus mosseae. In fact, all cactus plants treated with endomycorriza showed a significant increase in the vegetative and radical part of the plants, in the number of flowers per plant and in the duration of flowering. This endomycorriza can therefore also have beneficial effects on plants that are slow to grow and prolong the life of their flowers, beautiful to see but that normally short-lived. Further studies will be done on the use of mycorrhiza on cacti and succulents and the influence on resistance to biotic and abiotic stress of different typologies.
Highlights
The association between fungal hyphae and the radical organs of plants is a symbiosis that in 1885 Frank called mycorrhiza, meaning by this term a sort of new organ with its own shape and a certain physiology
The question that arises here is: what would happen if cactus plants such as Chamaecereus and Mammillaria, normally slow to grow, were treated with Glomus Mosseae? Can inoculation with Glomus mosseae improve flower production, plant growth and root development? the purpose of this work was to determine the changes in growth characteristics, root colonization, production and duration of blooms and new suckers caused by inoculation with G. mosseae
Prisa / World Journal of Advanced Research and Reviews, 2019, 02(03), 031–038 In Chamaecereus sylvestrii, the vegetative weight was 46,93 g in the thesis (GM), against 32,92 g of the thesis (CTRL) (Fig. 1A), 17,42 of the thesis treated with mycorrhizae against 7,25 g of the control thesis for the number of new suckers (Fig. 1B), 21,17 in the the thesis (GM) against 13,08 for the shoots number (Fig. 1C), 19,02 g in the thesis (GM) against 14,45 g for the weight of the roots (Fig. 1D) (Fig. 4B-4D)
Summary
The association between fungal hyphae and the radical organs of plants is a symbiosis that in 1885 Frank called mycorrhiza, meaning by this term a sort of new organ with its own shape and a certain physiology. A wide range of relationships can be established between plant roots and fungi. In these reports the plant does not show pathological symptoms due to the presence of fungal organisms. Three types of mycorrhizae are known: ectotrophic, endotropic, ectoendotropic, ectoendotropic. The fungus remains mainly outside the root, forming a sheath of variable thickness, consistency and colour. Ectrophic mycorrhizae are mainly found in forest plants and natural soils. The ectotrophic mycorrhizae are widespread mainly in the Pinaceae among the gymnastics and in the Betulaceae, Fagaceae and few other families among the angiosperms. The external appearance varies depending on the type of fungus, the intensity of the infection and the way the plant's root system grows [2]. The formation of the mycorrhizal roots is favoured by conditions of nutrient
