Title: Altered Dry Matter Partitioning of ´Starksur Supreme Delicious` Apple Trees by Nine Rootstocks
Authors: D. Strong and A.N. Azarenko
Abstract:
The dry matter partitioning to vegetative and reproductive components of 'Starkspur Supreme Delicious' apple (Malus domestica Borkh.) on nine rootstocks in the 1980-81 NC140 Apple Rootstock Trial
was determined in March, and again in Oct.-Nov. 1990. Trees on MAC.24 and M.7 EMLA had the
heaviest total tree dry weight (DW), while M.26 EMLA was intermediate.
Trees on OAR 1, O.3, M.9
EMLA, MAC.9, and M.9 did not differ, and M.27 EMLA had the least total DW. Total tree DW was
correlated negatively with percent of fruit, spur, and spur leaf DW and was correlated positively with
the percentage of frame, 2-yr and 1-yr wood, current season's growth, and shoot leaf DW.
