|標題:||Effects of Nitrogen on Plant Growth and Bulb Quality of Onion, Allium cepa, L.|
Plant growth, bulb quality and bulb storability of onion were significantly affected by nitrogen applications. Plant height, number of leaf, bulb diameter, neck diameter as well as bulb to neck ratio of both Tainan 2 and Texas early Grano 502 were increased during growth phase, but there were significant differences among five characterestics under nitrogen treatments. Expect neck diameter, characters of bulb weight, bulb diameter, bulb to neck ratio, percentage of bolting, bulbing and top falling showed significant responses to nitrogen fertilizers. Percentage of bolting decreased as nitrogen increased. Others showed a quadratic regression to nitrogen supply.
