Abstract
Adaptability to adverse soil conditions, date of spring budbreak and degree of vigor were evaluated in eleven new citrus rootstocks under semi-controlled screenhouse conditions.
One year-old rootstocks from the sour orange group (C. aurantium L.), mandarin group (C. reticulata B.) or hybrids of trifoliate orange (P. trifoliata) were container-grown in soils collected from various citrus growing regions of Israel, with various calcareous levels.
On the basis of trunk cross-sectional diameter, citrumelo citrange and sour orange developed at a significantly faster rate while the Avana mandarin was the slowest.
Initial budbreak was the earliest in the mandarin types.
Under calcareous soil conditions severe chlorosis developed in the leaves of the citrange and citrumelo types whereas the Rangpur-Troyer hybrid was the least affected.
Relative ranking of growth, budbreak and tolerance to calcareous soils is presented for all rootstocks tested.
