Abstract ▼ AI-Helper

The production of sweet (su) and super sweet corns (sh2) has been economically feasible in Korea in recent years. Major factors limiting super sweet corn production are low germination and low seedling vigor. Since seed quality is closely related to seed maturity, the optimum harvest time for the seed production of sweet and super sweet corns was studied and the quality of seeds with varying maturities was investigated in 2001 and 2002 cropping seasons. The parents of the sweet corn seeds were Hybrid Early Sunglow and 'Golden Cross Bantam 70' and those of super sweet corn were Xtrasweet 82 and 'Fortune'. Seeds were harvested at 21, 28, 35, 42, 49, and 56 days after silking (DAS). As the seeds developed, seed weight of sweet corn increased and the seed moisture content decreased faster than that of super sweet corn. Germination rates of sweet corn seeds harvested 21 and 28 DAS at $25^{\circ}C$ and emergence rates in the cold soil test were significantly lower than those of seeds harvested after 42 DAS in both years. Although the germination rates of super sweet corn seeds with varying maturities showed similar patterns as sweet corn seeds at $25^{\circ}C$, the emergence rate of super sweet corn seeds in cold soil test continuously increased with seed maturity. This suggests that seed quality of super sweet corn should be tested in a cold soil test to estimate field emergence. As the seeds developed, leakage of total sugars and electrolytes from the both sweet and super sweet corn seeds decreased up to 42 or 49 DAS. The $\alpha-amylase$ activities of both sweet and super sweet corn seeds increased with seed maturity from 21 to 35 or 49 DAS depending on genotype and year. The optimum harvest time for the seed production of sweet corn was 42 DAS and 49 DAS for super sweet corn considering emergence rate and plumule dry weight in the cold soil test, leakage of sugars and electrolytes from the seeds, and $\alpha-amylase$ activity.

제안 방법

In this experiment the optimum harvest time for seed production of sweet com was 42 DAS and 49 DAS for super sweet com considering emergence rate (Fig. 3) and plumule growth of seedlings in cold soil test (Fig. 4). A delayed harvest beyond the optimum harvest time may be damaged by the wild animals, preharvest sprouting, and infections of fungi in seeds dunng the hot, rainy season in Korea.

대상 데이터

The study was conducted during the 2001 and 2002 growing seasons at Gyeongsan, Korea. Since commercial inbred lines of sweet and super sweet com (Zea mays L.

이론/모형

Expenment design was a randomized complete block design with three replications in each com type. Statistical significance of treatment effects was determined using SPSS Standard Wrsion (2000). Germination and emergence rates data were analyzed after arcsin transformation.
The a-amylase activity of the seeds was measured by the method designed by Reiss (1994). Three seeds were soaked m distilled water at 25 ℃ for 7 days, dipped m liquid nitrogen, and ground m a mortar with a pestle.
