Influence of Biostimulants on Important Traits ofZinnia elegansJacq. under Open Field Conditions

Abstract

The efficacy of microbial treatment on growth, yield, and nutrient uptake is very well acknowledged for field crops. However, the use of microbes for Zinnia elegans has rarely been exploited under field trials. Therefore, in this study, we have evaluated the efficacy of different microbial bioinoculants on sixteen morphological and nine biochemical traits of Z. elegans. We used two arbuscular mycorrhizal fungi (AMF) (Glomus mosseae (G) and Acaulospora laevis (A)) along with Trichoderma viride (T) and Pseudomonas florescence (P) as five different treatments under open field conditions, in a randomized complete block design. There were significant differences for all of the traits studied. Treatment 5 (G + A + T + P) was noted as the best treatment for the improvement of morphological characters, whereas Treatment 4 (G + A + P) was most significant for the biochemical trait improvement in Z. elegans. Overall, this study provides useful insight into the bioinoculant treatment that can be applied to improve the yield and flower quality of Z. elegans under open field conditions.

Traversing arbuscular mycorrhizal fungi and Pseudomonas fluorescens for carrot production under salinity

“…Soil microbes regularly improve soil biodiversity by changing the unfavorable environment. AMF are obligate symbionts, where fungal associates assist the host by improving the uptake of water and minerals ( Saini et al, 2019a ). Preceding work on other root crops confirmed the progressive impact of AMF on growth and yield ( Yarzábal and Chica, 2017 , Ahmad and Gucel, 2016 ).…”

Assessing the Effectiveness of Mycorrhizal Inoculation on the Biochemical Composition of the Different Species of Echinacea

“…Still, other fields were subjected to consortium treatment as it was proven that consortium treatment enhances the growth and development of flowering plants. [18,19] Inoculation contains 70-72% G. mosseae colonized maize roots (⁓1 cm) and 610-630 spores (per 100 g of maize rhizospheric soil), 65-67% G. giganteacolonized maize roots (⁓1 cm) and 580-600 spores (per 100 g of maize rhizospheric soil), B. subtilis and P. fluorescence. First bacterial inoculation was given during the planting of seedlings in the flowerbed by merely dipping the roots in the respective broth media for 10 min.…”
