SUMMARY

Considering the lack of information about time of physiological maturity of maize seeds and it effect on seed quality, this work was aimed to evaluate physiological maturity effect on see quality of maize Seeds of different varieties were harvested at 25, 35, 45 and 55 DAS (Days after silking) at four different stages. Subsequently, the quality of seed samples determined in laboratory. It is analysed that seed harvested at 45 DAS showed maximum seed quality in terms of enhanced seed weight, seed germination, seedling length, seedling dry weight and seedling vigor index and minimum electrical conductivity of seed leachates was found at 45 days the silking. HQPM1 variety show maximum seed weight (30.27 gm) among 13 varieties. BIO 9681 variety show maximum seed quality parameters viz, seed germination (96.00 %), seedling length (35.51 cm) and seedling vigour (3760). JH3459 recorded highest seedling dry weight (1.60 mg) and there minimum electrical conductivity these observed in PMH1 (0.026). Differences in maximum seedling dry weight for maize cultivars attributed, that variation in genetic constitution. It concluded is maize cultivars, maximum seed quality could beachieved an physiological maturity which found at 45 Days after silking. dobre repliki imitatie horloges
