The basic tenet of the target plant concept is that the quality of nursery stock is determined by outplanting performance (survival and growth), rather than characteristics or standards measured at the nursery. This means that there is no all-purpose plant, but that each outplanting project will require different species and stock types. In this paper, we discuss the six basic questions that he...

Many newly set pineapple plants die from pineapple mite, Dolichotetranychus floridanus (Banks), infestations. Other infested plants remain small and produce very little or no fruit. Although this mite infests plants of all ages, it is a serious pest only on young ones. Nursery stock distributed or sold by nurserymen, or used by fruit producers, should be free of mites and other pests. Control o...

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 [...

Stable isotopes of carbon (δ13C) and oxygen (δ18O) in otolith cores (first 2 mo of age) of young-of-the-year (YOY) yellowfin tuna Thunnus albacares were used as natural tracers to predict the nursery origin of sub-adults (age-1) collected from the Hawaiian Islands. YOY fish were first collected from nurseries throughout the western and central Pacific Ocean (WCPO) to determine whether δ13C and ...

This paper proposes a hierarchical Bayesian framework for modeling the life cycle of marine exploited fish with a spatial perspective. The application was developed for a nursery-dependent fish species, the common sole (Solea solea), on the Eastern Channel population (Western Europe). The approach combined processes of different natures and various sources of observations within an integrated f...

Forest nurseries in Sweden produce ca. 360 million seedlings of Pinus sylvestris L. and Picea abies (L.) Karst. annually. Fungi represent the largest microbial component in rhizospheres and may significantly affect health and, consequently, quality of the seedlings. The aim of this study was to assess fungi focusing on pathogens in roots and the sphagnum peat growth substrate of healthy-looking...
