摘要
研究了百合小鳞茎在哈尔滨地区膨大发育过程中生物量累积与分配动态变化规律。结果表明,百合小鳞茎在哈尔滨地区的膨大发育过程可划分为5个阶段,即鳞茎失重消耗期、补偿期、充实膨大增重期Ⅰ、生长受抑期和充实膨大增重期Ⅱ。生物量分配规律:苗期至现蕾期以茎叶部分为主,现蕾后生物量主要分配于地下小鳞茎,分配于新鳞茎和根中的生物量始终很低。
The dynamic change of biomass accumulation and distribution of enlarging lily bulblet in cold Harbin area was studied.Lily bulblet enlarging development can be divided into five periods: bulblet weightless and consumption period,bulblet compensation period,the rapid enrichment and enlarging period Ⅰ,growth suppressed period,the rapid enrichment and enlarging period Ⅱ.Before budding stage the biomass was mostly allocated to the stems and leaves,after that the bulblet became the growth center,while the biomass allocation on daughter bulblets and roots was always low.
