Abstract

ホウレンソウ7品種 (パレード, 豊葉, 次郎丸, オーライ, おかめ, オリオン, オラクル) を栽培時期 (秋播き) および施肥を同一条件で栽培し, 還元糖, アスコルビン酸, シュウ酸, 硝酸の違いについて比較した。収穫は, 播種後41日目 (すべての品種), 48日目 (豊葉, 次郎丸, オーライ), 60日目 (オラクル, おかめ, オリオン) である。生育の早いパレードはアスコルビン酸, 還元糖の含有量が少なかった。豊葉, 次郎丸, オーライは生育途上から収穫適期までの生育でアスコルビン酸が増加したが, 豊葉は硝酸含量も増加した。オラクル, おかめ, オリオンは生育途上でもアスコルビン酸含量は多かったが, 収穫適期まで生育させても成分は増加しなかった。

Seven cultivars of spinach (<i>Spinacia olerancea</i> L.)-Parade, Hoyo, Jiromaru, Orai, Orakuru, Okame, and Orion-were studied under the same fertilization and climatic conditions. Changes in the contents of reducing sugar, ascorbic acid, oxalate and nitrate in each cultivar were determined. The cultivars were all harvested 41 days after sowing. Hoyo, Jiromaru, and Orai were harvested again 7 days later (at day 48), Orakuru, Okame, and Orion were also harvested again 19 days later (at day 60). The contents of reducing sugar and ascorbic acid in the fast-growing Parade were lower than in the other cultivars. The ascorbic acid contents of Hoyo, Jiromaru, and Orai increased as the harvesting time was delayed. The nitrate content of Hoyo also increased. The amounts of ascorbic acid in Orakuru, Okame, and Orion were higher than those of other cultivars throughout the growing period until day 41. However, they did not show any increase when determined at the harvest time.
