Influence of seed treatment with plant extracts on physiological parameters of amaranth, Amaranthus tricolor L

Though several treatments have been tested to envisage amaranthus seed emergence, seed treatment is one of the important technologies to find out the significant interaction among the test used, the cultivar and the environmental conditions through seed emergence. Hence a laboratory experiment was conducted to calculate the emergence of amaranthus seeds of cultivar CO-3 in 2013 at the Seed Technology Laboratory, Vanavarayar Institute of Agriculture, Pollachi, TN. The study was done in a completely randomized design consisting of six green leaf extracts (Cassia fistula, C auriculata, Annona squamosa, Dalbergia oliveri, Morinda tinctoria and Jatropha curcas) @ 5 per cent in the form of seed treatment and control using distilled water. The results indicated that there were significant differences in seed attributes due to the application of leaf extracts. Seed quality parameters were found to be high in seeds treated with M tinctoria.
