Control Effect of Rare Earth Elements on Crown Rot Disease of Aspergillus Niger in Groundnut Plants (Arachis Hypogaea L.)
نویسندگان
چکیده
Five soil-transmitted pathogenic fungi (Aspergillus niger) were isolated and selected to investigate the effect of Rare earth elements on their disease causing ability. The present study reveals the response of leguminous plant (Arachis hypogaea L.) to monazite soil containing Rare earth elements. A significant increase in plant biomass, total chlorophyll content and stress resistant product (phenols) was observed. The results indicated that seeds soaked with REEs show significant disease controlling effects on root rot by the pathogenic fungi. The activities of two pathogenic enzymes (cellulase and pectinase) of the fungi were reduced by the application of REEs. The results indicated that REEs in agriculture not only promote the biomass but also control the soil pathogens.

Groundnut or peanut (Arachis hypogaea L.) is one of the important economic oilseed crops of the world. The cultivated groundnut belongs to family Fabaceae, subfamily Papilionaceae. Groundnut is grown in nearly 100 countries. It occupies 21.7 million ha worldwide with a total production of 38.6 million tonnes during 2011 (FAOSTAT, 2011). Among the soil-borne fungal diseases of groundnut, stem ro...

Groundnut seed priming was performed with an aqueous solution of gibberellic acid (GA3) (0, 50, 100, and 150 ppm for 18h) and accelerated aging (96 h) was done prior to drought stress (-0.4, -0.6, and -0.8 MPa), then recovered. Investigated traits were germination percentage, mean germination time, germination rate, vigor index, plumule length, radicle length, seedling length, malondialdehyde c...

Low viability and poor vigour due to seed deterioration are major problems for successful agricultural production. In this experiment, the ability of hydropriming to ameliorate seed deterioration damage was studied in groundnut. Groundnut seeds were subjected to accelerated ageing for 96 hours at 40 °C and then hydroprimed at 25 °C for 6, 12 and 18 hours. Regardless of duration, hydropriming si...
