The vascular cambium, which produces xylem and phloem cells, originates from procambium that has not completely differentiated during the formation of primary xylem and primary phloem. DICOT STEM ... Cambium. The primary function of the cambium is to produce the vascular tissue and hence it is called the ‘Vascular Cambium’. • Vascular Cambium and • Cork Cambium Activity Generally monocots do not have secondary growth, but palms and bamboos have woody stems. Seasonal activity of cambium has been investigated in Salvadora persica L., one of the commonest evergrenn tree of northern India, from March, 1974 to February, 1975 in the main stem and the branch. The vascular cambium is the main meristem in the stem, producing undifferentiated wood cells inwards and bark cells outwards. This gives rise to secondary xylem initials centripetally and secondary phloem initials centrifugally. The annual increase in diameter of woody stems results from cell division in a circular meristem called the cambium or vascular cambium which is located just under the bark of trees and shrubs. However, Line 51 showed unlinked vascular cambium and isolated fascicular cambium bundles in the 2 nd internode (Figure S7a,c).
