Description
English: A bulb of a tulip. During rapid spring growth, the bulb exhausts its stored nutrients and shrinks in size. A white stolon, carrying the bud of a new bulb, bursts through the base of the old bulb and drives the bud deeper into the soil. By the end of spring season the old bulb will be reduced to dry dead sheaths; the new bulb will be ready for re-planting in the end of summer. This type of bulb reproduction is typical for immature tulips; only a few species like T.praestans continue it after first blooming.
Русский: Воспроизводство луковицы тюльпана столоном углубления. Старая луковица израсходовала запасы питательных веществ, отдав их зелёному листу, её недавно полные крахмала чешуи заметно уменьшились в размерах, усохли. Прежде чем погибнуть, старая луковица выбрасывает вниз белый столон углубления, несущий зачаток новой луковицы. Спустя несколько недель старая луковица окончательно усохнет и отомрёт, а новая луковица продолжит развитие и к концу лета будет готова к пересадке. Этот тип репродукции с ежегодным заглублением новых луковиц характерен для неполовозрелых тюльпанов (начиная с второго года жизни). В зрелом возрасте так размножается лишь несколько видов (T.praestans и др.); у этих видом могут образовываться не только одиночные, но и множественные столоны.
