Propagation of Pecan by Stem and Root Cuttings

Abstract

<jats:p>Certain key experiments on the clonal propagation of pecan by stem and root cuttings are described. Juvenile cuttings of pecan cv. `Stuart' produced more roots and a larger percentage of rooted cuttings than adult cuttings when treated with 1% solution of (IBA) in Feb. and Aug. Successful propagation from `Stuart' stem cuttings was high from July to September. This study also fails to support the hypothesis that auxins are necessary to increase the level of rooting by pecan hardwood cuttings. Pecans were propagated using root cutting techniques and successfully transplanted to containers. Root cutting sections collected in either March or August from two-year-old `Curtis' seedling, responded yielding high rooting success and survival. The data also provides evidence that IBA could enhance the production of roots of root cuttings but BA (Benzyl Adenrine) offers no benefit. Girdling the sprout shoots from root cuttings with the use of IBA doubled the percentage of shoots producing roots and increasing root length.</jats:p>

Differential Protein Analysis of Pecan Hardwood Cuttings

“…A rooting method for pecan cuttings by treating with root-inducing chemicals, such as lanolin mixtures of indole butyric acid, was first reported in the early 19th century (Smith and Romberg, 1939). Since then, new treatment protocols have been explored (Allan et al, 1980;Brutsch et al, 1969;Fouad et al, 1992;Smith and Chiu, 1980;Wolstenholme and Allan, 1975) to induce roots for pecan stem cuttings. To understand adventitious root formation, the anatomy of roots for pecan stem cuttings has been studied (Brutsch et al, 1977;Fayek et al, 1994).…”
