 note = {関東地域で収穫可能なダイジョの1品種を用いて,地下部の塊茎のみならず塊茎デンプンのソースである地上部の茎葉における生長過程の含水率の変化を調べた。その結果,生長時期の推移に伴う茎葉含水率と塊茎の含水率の変化には顕著な差異が認められた。すなわち,茎葉の含水率は生長期間の大半を通して緩やかに減少するが,塊茎の含水率は肥大初期に急速に減少し,その後横這いから緩やかな減少傾向を示した。塊茎では,肥大初期にはその組織が主に若い柔組織細胞で構成されているため水分含量が高いが,肥大が旺盛になるにつれてデンプンの蓄積が進み,それに伴って含水率が低下したものと推測された。このことから,ダイジョの塊茎の含水率の推移は,品種の塊茎成熟度の特性を評価する有効な方法となる可能性が考えられた。, Greater yam (Dioscorea alata L.) is one of the yams and still a staple food tuber crop in parts of developing and self-sustaining agriculture in tropical Asia. Yam tuber contains high moisture content, which changes during growth stages. The present research investigated changes of moisture content in tubers and tops of an early cultivar, which is able to riper in the Kanto Metropolitan area. According to the results, remarkable differences were observed in changes of moisture content of tubers and tops of growing plants. Moisture content of tops gradually decreased throughout whole growth stages, while that of tubers rapidly decreased at the early stage of growth and thereafter tended to reduce gradually. In the earlier stage of growth, tubers consisting of young parenchyma seems to maintain higher moisture content. But as the growth of tuber progresses, starch is accumulated and moisture content of the tuber is thought to be reduced. From these results, the changes of moisture content in tubers will be an useful indicator for tuber maturity., E, 4, KJ00004074170, 論文, Article},
