Isolating a Leaf in Rooted Trees via Random Cuttings
We consider a recursive procedure for destroying rooted trees and isolating a leaf by removing a random edge and keeping the subtree, which does not contain the original root. For two tree families, the simply generated tree families and increasing tree families, we study here the number of random cuts that are necessary to isolate a leaf. We can show limiting distribution results of this param...
متن کاملEfficiency of Seedlings and Rooted Cuttings for Testing and Selection in Pinus taeda
Predicted genetic gains of polymix, cloned polymix, full-sib and cloned full-sib testing and selection options for a breeding population were estimated for Pinus taeda L. Heritabilities for volume from the clonal testing were considerably greater than the heritabilities from the seedling testing. Cloned options had higher expected genetic gains than seedling options, even after adjusting for th...
متن کاملStudies of Tissue Colonization in Rhododendron by Phytophthora ramorum1
The knowledge on latency is of great importance to prevent the spread of Phytophthora ramorum with healthy looking plant material. To learn more about the tissue colonisation in Rhododendron, histological studies with epifluorescence microscopy have been started. Epifluorescence images showing P. ramorum structures in different tissues are presented. A first idea of P. ramorum development in Rh...
متن کاملEffects of Nursery Characteristics on Field Survival and Growth of Loblolly Pine Rooted Cuttings
Morphological characteristics of rooted cuttings and seedlings of four open-pollinated loblolly pine families cultured at the G.H.W. Weyerhaeuser Nursery near Washington, North Carolina were assessed after lifting. Cuttings were visually assigned to nine grading classes and six putative cull classes. The nine grading classes represented a factorial of three root collar diameter classes (small [...
متن کاملTen-year growth comparison between rooted cuttings and seedlings of loblolly pine
Rooted cuttings and seedlings of loblolly pine (Pinus taeda L.) were established in a central Alabama field trial. Five, full-sib families, with an average number of six clones per family, were evaluated. Mean cutting/seedling height ratios revealed that despite initial differences in size, relative growth rates of both propagule types stabilized and were equal by age 7 years. Through age 10 ye...
