Abstract EN
Inoculation of the bacterial cells of microbial seed coating agents (SCAs) into the environment may result in limited survival and colonization.
Therefore, the application efficacy of an encapsulated microbial seed coating agent (ESCA) was investigated on potted cotton plants; the agent was prepared with polyvinyl alcohol, sodium dodecyl sulfate, bentonite, and microencapsulated Bacillus subtilis SL-13.
Scanning electron micrography revealed that the microcapsules were attached to ESCA membranes.
The ESCA film was uniform, bubble-free, and easy to peel.
The bacterial contents of seeds coated with each ESCA treatment reached 106 cfu/seed.
Results indicated that the germination rate of cotton seeds treated with ESCA4 (1.0% (w/v) sodium alginate, 4.0% polyvinyl alcohol, 1.0% sodium dodecyl sulfate, 0.6% acacia, 0.5% bentonite, and 10% (v/v) microcapsules) increased by 28.74%.
Other growth factors of the cotton seedlings, such as plant height, root length, whole plant fresh weight, and whole plant dry weight, increased by 52.70%, 25.13%, 46.47%, and 33.21%, respectively.
Further analysis demonstrated that the peroxidase and superoxide dismutase activities of cotton seedlings improved, whereas their malondialdehyde contents decreased.
Therefore, the ESCA can efficiently improve seed germination, root length, and growth.
The proposed ESCA exhibits great potential as an alternative to traditional SCA in future agricultural applications.
