بررسی همبستگی جوانه‌زنی و بنیة بذر ارقام هیبرید ذرت شیرین با درصد ظهور گیاهچه در مزرعه

This study was conducted to compare the seed quality of two hybrid sweet corn and to determine the correlation of seed germination and vigor with seedling emergence percent at field at seed quality analysis laboratory and field of seed and plant certification and registration institute in 2012. The experimental design was factorial with 2 factors in 3 replications. The treatments were 2 cultivars (KSC403 and PA213) and initial germination percent of seeds at 4 levels (75%, 80%, and 85% and90%). The measured traits were radical emergence percent, seedling dry weight, radicle length, and shoot length and seedling field emergence. The results indicated that there was a significant difference between two cultivars in radicle emergence percent at laboratory test and seedling field emergence percent at 1% level of probability. Significant difference was recorded among 4 levels of germination in all measured traits except of radicle length. Also a significant correlation was observed between germination and seedling field emergence.
