Trichoderma harzianumRifai: A Beneficial Fungus for Growth and Development ofAbroma augustaL. Seedlings with Other Microbial Bio-Inoculants

Abstract

Rhizospheric microbes play an important role in plant health. Rhizosphere is an area around the roots of plants where all microbes repose and influence the health of plants. These microbes require organic matter for their activity and provide nutrients to the plants and maintain the plant health. In this research paper, these useful microbes like fungi (Trichoderma harzianum), endomycorrhizae (Arbuscular Mycorrhiza) and bacteria (Pseudomonas putida) were isolated and after mass multiplication applied as bio-inoculants in alone and in combination to see the effect on growth and development of Abroma augusta seedlings which is a threatened medicinal plant in north-eastern part of India. T. harzianum alone and in combined form showed significant growth and development effect on seedlings. The effect of alone and combined treatments of T. harzianum on growth and development of this important medicinal plant species has been discussed in detail in this research paper.

Trichoderma spp. in Growth Promotion of Jacaranda Mimosifolia D. Don

“…The laboratory results for shoot length (SL) were reproducible in the greenhouse, since the seedlings treated with the T. harzianum SIMBI T5 and T. harzianum ESALQ1306 strains provided higher height (H) values for the resulted plants. The species Trichoderma harzianum has already demonstrated its potential for use in the production of plants in the species of Abroma augusta, possibly through the secretion of some substances in the rhizosphere, responsible for the better development in the plant shoot (Parkash et al, 2019), as well as also found in the species of Cedrela odorata, wherein the association between plant-microorganism provided increases in plant height (Dí az & Gonzá lez, 2018).…”
