一、大梅花蘿蔔種子因採種地環境之不同，影響種子之大小，可超過一倍以上，海拔1,200公尺之南山村採種者，每1,000粒種子重量為11. 94公克，平地海岸布袋地區採種者，為5 . 9 17公克。 二、粗蛋白質之含量，小粒種子較多於大粒種子，粗脂肪之含量，大粒種子較多於小粒種子。 三、播種後20天，幼苗生長情形， 不論幼苗直徑、子葉大小、幼莖高度，低海拔地區之小粒種子，均較高海拔地區之大粒種子為小。 四、成苗之生長速度，至最後收穫時之真葉數相同，其高度約略相等，但在生育中期，播種後60天調查，大粒種子仍見優勢。五、至最後收穫時調查塊根收量，高海拔地區生產之大粒種子，產量均多於低海拔地區生產之小粒種子。 六、至於塊根形態之變異，空心以及皮厚程度， 塊根頂端直徑之變化， 塊根佔葉重之百分比，無明顯之區別。
1, Both the size and weight of 1,000 seeds were much affected by origins having different environmental conditions. For instance, the weight of Pu-Tai. 2. The crude protein contents of smaller seeds were higher than larger seeds. But the contents of crude fat showed reverse order. 3. At the 20 days after sowing, the growths of seedlings got from large seeds were faster than those of small seeds. At the harvesting time, the differences of the plant height were not significant. 4. The plots of larger seed showed higher yields than those of the smaller seeds. The differences were from 14 to 54%. The shape of roots were not significantly affected by seed sizes. 5. The author considers that the large seeds are rich in vitality, therefore the seedling may grow rapidly and vigorously inspite of the unfavorable conditions, such as drought, insect or disease damages.
