Studies on the translocation of 45Ca in the apple tree. I. Transport and distribution in relation to the time of uptake

, : Studies on the translocation of 45Ca in the apple tree. I. Transport and distribution in relation to the time of uptake. Gartenbauwissenschaft 38(2): 91-108

Cox's Orange Pippin apple trees on M.9 rootstocks grown in sand culture in pots outdoors were labelled with 45Ca via the roots at 3 different times, viz. immediately after dormancy until the end of flowering (23 March - 15 May), during early fruit development (2-16 June) or after shoot growth had ceased (16-30 August). In the first period 45Ca was found in the inflorescences several days before full flowering.

The isotopic enrichment between an animal and its diet can vary among and within living systems, but the sources of variation are not yet fully understood. Some studies have found that diet quality or an animal's nutritional status can influe...
