Abstract

アスパラガス'グリーンタワー'の1年生株を用いた養成時の生育と促成栽培における若茎の収穫量および品質の雌雄間差を検討した.1.アスパラガスの養成株における雌雄間の形態的な差異として,雌株は雄株に比べて草丈および第1側枝の位置が高い傾向がみられた.雌の1年生株は,果実の着生が少なく,雌雄間での発生茎数の差がなく,雌株は雄株に比べて茎経が太く生育が旺盛であった.2.1年生株の促成栽培では,若茎発生数には雌雄間差はなく,雌株は1本重が重いL規格の発生数が多く,若茎重の合計で雄株より優った.3.雌株が雄株に比べ若茎頭部のしまりが良く,りん片葉のアントシアニン発生が少なかった.4.以上のことから,1年生株を用いた促成栽培では,雌株を判別して用いた方が有利であると判断された.

The differences between male and female plants in the growth of one-year-old asparagus (Asparagus officinalis L.), yield and quality of spear in forcing culture were investigated. Female plants had higher stalks and longer length to primary branch than male plants. One-year-old female plants produced a few or no fruits. There was no difference in the number of stalks between one-year-old male and female plants. One-year-old female plants grew more vigorously and produced larger stalks than males. The difference between one-year-old male and female plants in the number of spears was not significant. However, the size of individual spears of one-year-old female plants was larger than that of male plants. Thus, one-year-old female plants have a capacity for a higher spear yield than male plants in forcing culture. The spear top of female plants was tighter than that of male plants. Female plants developed less anthocyanin pigments in the scaly leaves of spear than male plants. These results suggested that female plants were more desirable than male plants in one-year-old asparagus forcing culture.
