Abstract
In the present investigation five treatments with pendimethalin concentrations namely 0.5, 1.0, 2.5, 5.0 and 10.0 ppm were given to maize cv. NAC-6002 grains to evaluate herbicidal toxicity on germination and early growth. The seedlings were maintained upto 15 days. Embryonic axis and endosperm of 4, 6, 8, 10 and 15 days old germinated soybean seedlings were used for bioassay on biochemical parameters viz., total protein, total carbohydrate, starch and reducing sugar were carried out. Germination percentage, length of radical and plumule were decreased significantly with increase in concentration of pendimethalin. The germinating seedlings of treated set showed high content of seed serves viz., total protein, total carbohydrate, starch and reducing sugar in the endosperms, whereas it was low in the shoot-root axis at all the days of observation over control. With increase in the days of germination the seed serves (protein, carbohydrate, starch and reducing sugar) showed a drastic decrease in control, whereas in treated sets the rate of seed reserves degradation was slow in the endosperm. On the contrary, in shoot-root axis a reverse trend was recorded in response to pendiemthalin treatment. The effect was more pronounced at higher herbicidal concentration. These results reveal that the mobilization of seed reserve was suppressed by pendimethalin, as result of impaired degradation of seed reserve, during germination and early growth.
