Appraisal of Shannon Diversity Index of mycorrhizae in mulberry crop: a preliminary study
摘要
Mycorrhizae have been considered safe and boost mulberry plant growth through nutrient acquisition, biotic stress, and abiotic stress management. More than 90% of all plant families studied (80% of species) in both agricultural and natural environments form mycorrhizae associations and they can be essential for plant nutrition. Mycorrhizae are found in a wide range of habitats, including deserts, lowland tropical rainforests, high latitudes and altitudes, and aquatic ecosystems. There are a few exceptions to the rule that mycorrhizae are found in all plant species that are economically important to man. This study aimed to identify and study the species richness and diversity of mycorrhizae. Having a variety of mycorrhizae in the soil is essential for the preservation of ecosystems and their services. Mycorrhizae associations are widespread amongst plant families and appear to have evolved and spread with the early land plants (effectively enabling early plants with small ineffective roots to invade and become established in the terrestrial environment). This study identified three species—Glomus sp., Acaulospora sp., and Funnelliformis sp.—after analyzing 10 rhizosphere soil samples from the Central Sericultural Research &Training Institute, Berhampore. Acaulospora sp. accounted for 54% of the population, was prevalent over all areas, and had the highest Shannon Diversity Index (0.36). The spore diameters of Funnelliformis were 152–160 μm, Acaulospora sp. were 140–200 μm, and Glomus sp. were 22–244 μm. These results demonstrate the importance of Acaulospora sp. in the ecosystem, supporting plant resilience, soil health, and nutrient absorption. Clarifying plant–microbe interactions and promoting sustainable farming methods require further molecular research.
