ABSTRACT
A laboratory experiment was conducted to correlate the germination test with seed vigour parameters and enzyme activities to predict seedling vigour and planting value on late sown wheat variety UP-2526. The experiment was conducted at GBPUA and T, Pantnagar during rabi season of 2020-2. The experiment consisted of five treatments viz; no priming (control), hydropriming, 10%, 25% and 50% kunapajala priming for 16 hrs. Results revealed that germination percentage was positively and significantly correlated with speed of germination (0.914*), seedling vigour index-II (0.890*), α-amylase activity at 12 and 16 hrs of priming (0.942* and 0.947*, respectively), seed reserve mobilization efficiency on 4th day (0.954*) after incubation and imbibition rate after 16 and 24 hrs of soaking duration (0.933* and 0.894*, respectively). Heat stress both low and high temperature are major reason of declining yield in wheat when sown delayed. Prediction of seedling vigour and field emergence of seed before sowing is prime important for assured yield in late sown condition.
