Title:
Asexual Reproduction of Trees by Air-Layering

Author:

pp: 387

Abstract:
INTRODUCTION

Air-layering is considered a useful and successful technique for producing new plants from mature trees, especially on difficult-to-root tree species. It is also a technique with the advantage of producing and propagating larger plants in a short period of time. We have attempted to root various hybrid species of Prosopis chilensis, hybrid species of Cercidium, Ficus macrocarpa (syn. F. nitida), and Chilopsis linearis. Prosopis grown from seeds exhibit wide genetic variations in growth rates, growth habit, leaf morphology, and frost tolerance. The Cercidium hybrids either produce sterile seeds or seeds do not produce plants identical to the parents. This study was initiated to investigate the potential of air-layering as an alternate vegetative propagation method for producing identical clones of superior quality for the southwestern U.S.A. Rooting of air layers of Prosopis cineraria in India (Solanki et al., 1986) and of Acacia koa in Hawaii (Skolmen, 1977)
