Effect of Vesicular Arbuscular Mycorrhiza <i>Glomus fasiculatum</i> on the Growth and Physiological Response in <i>Sesamum indicum</i> L.

Abstract

Plant growth and physiological response of sesame (Sesamum indicum L.) were studied in controlled environment using normal soil and indigenous Vesicular-arbuscular mycorrhiza (VAM) fungi treated soil. The seedlings of Zea mays were inoculated with Giguspora species of VAM (Glomus fasiculatum) and the inoculum was multiplied with help of Zeamays seed bed. Sesame seeds were then inoculated into the bed and it was found that the plant height, shoots lengths, roots, biomass of shoot and roots were considerably increased in the mycorrhizal plants. The effect of VAM infection was assessed in pot experiment. In this comparative study, specific mycorrhizal fungi had consistent effects on various growth parameters such as the number of leaves, number of roots, shoot length, biomass of shoot and roots and biochemical parameters were observed at various time intervals by statistical analysis using two way ANOVA, it was confined with mycorrhizal and nonmycorrhizal infected plants. It was found that the ability of isolates to maintain the plant growth effectively in the case of mycorrhizal seedlings shows a maximum absorbtion of 0.77 ±0.2, shoot length is about 8.34 ±0.2, count of root and leaves are about 8.10 ±0.3, 5.6 ±0.3 respectively under mycorrhizal infection in 30days of analysis and had a positive effect on the growth at all intervals. Biochemical analysis were carried out to estimate the total chlorophyll, chrophyll A, chlorophyll B and Carotenoids contents and it was analyzed to be 9 ±0.5 mg/g, 8.3 ±0.5 mg/g, 3.6 ±0.5 mg/g, 4 ±0.3 mg/g respectively. At the 30 th day of analysis for the mycorrhizal plants, it was found to be high in mycorrhizal seedlings which shows the symbiosis had improved the nutrient uptake of cultivated plants. Nevertheless G. fasiculatum was found to be the most efficient fungus and exhibited the highest levels of mycorrhizal colonization, as well as the greatest stimulation of physiological parameters.

Effect of Cobalt Application and Mycorrhizal Fungi Inoculation on Growth and Some Nutrients Content of Barley and Egyptian Clover Plants Grown in Calcareous Soil

“…Mycorrhizal plants roots hyphae can increase the branching of root system in rhizosphere so that mycorrhizal plants roots have more absorption efficiency compared to non-mycorrhizal ones. These results are in agreement with those found by Nourinia et al (2007) and Robinson et al (2014).…”

Reduction Possibility of Phosphorus Using With the Application of Mycorrhiza in Purple Coneflower (Echinacea Purpurea L.) Through Physiological Traits and Essence Yield Under Different Irrigation Levels

“…Chlorophyll a and carotenoid content were not affected by mycorrhiza but chlorophyll b content was only affected by mycorrhiza which decreased it. Robinson et al (2014) showed that the application of mycorrhiza increases the chlorophyll b content in sesame.…”

“…Das (2015) examined the type of mycorrhizal fungus in 12 herbal medicines and observed that, the type and intensity of fungal coexistence varied in different plants. Robinson et al (2014) examined the effect of mycorrhiza on physiological growth and response of sesame. The application of mycorrhizal fungus enhanced the number of leaves, number of roots, the length of the aerial organ, the root biomass and chemical parameters.…”

Evaluation of Arbuscular Mycorrhizal Fungi of Orchard Soils for Growth Improvement in Maize under Protected Conditions

“…The mycorrhizal association helps the host plants in overcoming several biotic and abiotic stresses and improves plant growth. Robinson et al, (2014) reported increased plant height, root length, shoot length, root biomass and shoot biomass in berseem plants due to AMF inoculation. Several AM fungi namely Glomus fasciculatum, G. mosseae, G. macrocarpum and Sclerocystis dussii were screened by Dutt et al, (2013) in apricot (Prunus armeniaca L.) cv.…”
