摘要
研究了郁金香栽培品种‘Judith Leyster’露地栽培条件下,子球的生长变化规律。结果表明,茎叶主要于始花期后为子球的生长提供同化物;子球于展叶盛期后开始膨大发育,其生长的关系为更新球大于内子球,而各层内子球从外到内依次增大;外子球于结实始期后独立生长。
The growth of daughter bulbs were investigated in the cultivar ＇Judith Leyster＇ of Tulip hybridus planted in the field.Distribution of assimilations was mainly allocated into daughter bulbs by leaves and shoot after initial bloom period.The development of daughter bulbs swelled at the period of leaf-expansion and regenerated daughter bulb grew larger than all inner daughter bulbs which followed increase from outside to inside,but the growth of exterior daughter bulb was independent after initial fruit period.
