Evaluation of Plant Growth Promoting Ability of <i>Bacillus amyloliquefaciens</i> Bc2 and <i>Trichoderma harzianum</i> TR <i>In Vivo</i>

Abstract

Bacillus amyloliquefaciens Bc2 and Trichderma harzianum TR were used to evaluate their growth-promoting activity on cultivated strawberries, under laboratory and field conditions, and we have noticed that the percentage of achene germination is important for ones treated with TR (=97%) followed by those treated with Bc2 strain (=90%) and the control (=84%). Inoculations on field showed that on untreated soil with insecticide, TR is effective and allows the development of plants and extends the duration of flowering and fruiting. On treated soil, Bc2 clearly promotes the growth and development of strawberry seedlings and its role as plant growth promoting microorganisms has been proved.

Performance of Trichoderma harzianum and Bacillus amyloliquefaciens Bioformulation on Germination and Expression of Bioprotective Molecules against Cercosporiosis in Abelmoschus esculentus in the Field

“…The work of Rababe et al [22] demonstrated the ability of T. harzianum on Fragaria vesca to stimulate germination via secreted phytohormones. It has also been shown that seed germination can be effective when seeds are pre-treated in a solution containing either T. harzianum or B. amyloliquefaciens, as the latter secrete phytohormones like gibberelin that break their dormancy [23].…”
