摘要: 研究了唐菖蒲栽培品种‘Traderhorn’和‘Advanced Red’露地栽培条件下, 不同种植期匍匐茎和子球的生长发育规律。结果表明: 匍匐茎由新球基部鞘叶叶腋间的腋芽发育而来, 在植株4~6 叶期花序抽出前形成, 新球中部茎节匍匐茎生长最佳; 种植90~110 d 后匍匐茎顶端膨大形成子球。5 月底种植有利于子球数量和质量的增加。

Abstract: Growth and development of stolon and cormel were investigated in two cultivars‘Traderhorn’and ‘Advanced Red’of Gladiolus hybridus planted at three dates in the field. Stolon come from the axillary buds on the nodes with sheath leaf which located at the basal nodes of new corm. It was formed at 4 - 6 leaf stage before spike emerging. In the middle nodes , stolons revealed more vigorous growth. Cormels appeared after planting 90 to 110 days at the tip of stolon. Number and fresh mass of stolon and cormel were increased by delaying planting time to the end of May.

Key words: Gladiolus, Stolon, Cormel, Growth and development
