魔芋在世界大多数地区都不能正常结实。本试验以花魔芋(Amorphopha-llus rivieri Durieu)及白魔芋(A.albus P.Y.Liu et J.F.Chen)为材料,将成熟花粉授到即将开花的柱头上就能顺利地获得果实。因此认为在重庆地区魔芋不能正常结实主要原因是雌蕊先熟。有趣的是,包被在果壁内发育成熟的不是一个真正的植物学种子,而是一个小块茎。解剖研究表明,小块茎由块茎原始体发育而来。魔芋块茎维管组织分散排列,没有由维管形成层引起的次会生长,只有木质部周围发生的决生形成层和薄壁细胞分裂活动,产生大量薄壁细胞使块茎膨大。块茎的保护组织为叠生木拴。 魔芋块茎由依赖母体营养到脱离母体营养的最后时期在七月,此时植株活力最盛。换头之前生长量的变化主要在叶上,换头之后块茎急剧膨大。不同大小块茎作种,块茎膨大效率(TBE)不同,较小的块茎具有较大的膨大效率,较大的块茎净增重较大,这是生产上选用种芋必须考虑的问题之一。
Konjac does not work well in most parts of the world. In this experiment Amorphopha-llus rivieri Durieu and A. albus P.Y. Liu and J.F. Chen were used as materials to successfully harvest the mature pollen from the flowering stigma. Therefore, the main reason that konjac can not be normally robust in Chongqing is that pistils are first cooked. Interestingly, instead of being a true botanical seed, the coating matured within the fruit wall, but a small tuber. Anatomical studies have shown that small tubers develop from tuber primitives. Konjak tubers vascular tissue dispersed arrangement, there is no secondary vascular growth caused by the formation of growth, and only the xylem occurred around the formation and parenchyma cell division activity, resulting in a large number of parenchyma cells expand tubers. Tuber tissue protection for the stack of wooden tied. The last period of konjak tubers, which rely on maternal nutrition to be free of maternal nutrition, is at its peak in July. Changes in growth before the change in the main leaves, after the head swollen swollen. Different sizes of tubers, tuber expansion efficiency (TBE) is different, smaller tubers have large expansion efficiency, larger tubers net weight gain, which is the production of species selection of taro one of the issues to be considered.
