ADVENTITIOUS ROOT FORMATION IN LEAF-BUD CUTTINGS OF TEA (CAMELLIA SINENSIS L.) FATMA KOYUNCU* AND FIKRI BALTA
Abstract: Anatomical changes during adventitious root initiation are described
in cuttings with single leaf and node of Turkish tea (Camellia sinensis
L.) clone Fener-3. In this clone no preformed root initials or primordia
were found. The rooting process consists of these stages; cuttings exhibited
meristematic activity of vascular zone (especially, phloem parenchyma),
root initial formation, differentiation of root primordia, and root
elongation. Thus, adventitious root primordia arose from near the vascular
cambium and secondary phloem parenchymatous tissue also contributed.
Continuous cell division, elongation and differentiation within callus
gave rise to formation of root primordia. Presence of perivascular fibers
and sclereids did no mechanical barrier in inhibition of root formation
and to retard rooting. The development of adventitious roots is directly
correlated with the appearance of root initials. According to the process
of root initiation, cuttings of Fener-3 Turkish tea clone may be described
as easy to root. Department of Horticulture, Faculty of Agriculture, University of Süleyman Demirel, Isparta, Turkey. Corresponding Author: fkoyuncu@ziraat.sdu.edu.tr |
