本文進行探討甘藍(Brassica oleracea L. Capitate group cv. Oscar)種子大小對發芽、萌牙、幼苗生長與加速老化之影響，將1984年採收具高活力之兩批種子1984-1與1984-2分成三級之種子爲對照。在標凖發芽試驗中顯示發芽與正常幼苗之百分率不受種子大小影響，在人工氣候室9~25℃之溫度範圍內，幼苗萌芽百分率萌芽速率亦不受影響，然而，幼苗鮮重與種子大小卻有極密切之關係，種子越大，幼苗生長越佳，因此，甘藍幼苗之生長係受種子大小所左右。
The effect of seed size of cabbage seeds (Brassica oleracea L. Capikita group cv. Oscar) on germination, emergence, seedling growth and the sensitivity to rapid ageing were studied. Seed lots of 1984-1 and 1984-2 showing high vigour were separated into 3 fractions, unsorted seeds served as control. Seed size had no effect on germination and percentage normal seedlings in the standard laboratory germination test. It did also not affect the final percentage emergence at temperatures ranging 9 from 25℃ at phytotron conditions, nor the rate of emergence. However, seedling fresh-weight was closely related to seed size, the larger the seed, the better seedling growth. Thus, seed size influenced seedling growth irrespective of the physiological age of the seeds.
