Interpretation:
Isolation, screening and characterization of beneficial rhizosphere bacteria associated with healthy (field-resistant) coconut palms in root (wilt)
disease endemic hotspot areas of Kerala.
One hundred and ten rhizobacterial isolates associated with healthy coconut palms of root (wilt) diseased tract of Kerala were isolated
and screened in-vitro for IAAproduction and solubilization of fixed forms of mineral nutrients. Seven isolates showing multiple phytobeneficial properties
were characterized and the selected isolate was tested for
its biopriming effect on maize.
Of the total isolates screened, 54 isolates
produced IAA. Among the nutrient solubilizers, silicate
solubilizers (57%) and phosphate solubilizers (48%)
dominated. Of the seven isolates with multiple
phytobeneficial properties, five rhizobacterial isolates
belonged to Enterobacteriaceae family including three
Enterobacter spp. The isolate T4HFB9 belonged to
Acinetobacter sp.. The green fluorescent Pseudomonas
isolate K3HPSB2, showed 99% sequence similarity with
Pseudomonas migulae. Seed biopriming of maize with
Pseudomonas sp. strain K3HPSB2 recorded significant
increase in germination percentage and seedling vigour
index over untreated control.
Disease-resistant coconut palms in RWD endemic tracts host a good proportion of phytobeneficial rhizosphere bacteria,with
demonstrable multiple plant growth promoting traits. Multi-nutrient solubilizing Pseudomonas sp. with bioinoculant prospects has been selected for
further studies on bio-priming for palm health management in RWD endemic tracts
