| 摘 要： | The growth dynamics of root system and aboveground of the grafted seedlings of different Camellia oleifera cultivars are studied by skeleton method and root scanning. The results of 8-months’ observation on grafted seedlings of 5 C. oleifera cultivars showed that: the growth of aerial parts and root of the C. oleifera seedlings were not entirely in sync, during the time of low temperature from November to February, the root system still in sustained growth though the aerial parts of the 5 cultivars grew slowly. Remarkable differences were existed in root length, root surface area, root volume, root biomass and other indicators after 11-months’ growth. The mean value of total length of root-system was up to 243.3 cm and 143.4 cm for the minimum, the mean value of total root surface area was up to 50.2 cm2 and 31.7 cm2 for the minimum, the mean value of root volume of the C. oleifera seedlings was up to 0.843 cm3 and 0.578 cm3 for the minimum which lived 11 months after grafting. All the root length, root surface area, root volume of the 5 cultivars have remarkable differences. |
