The genetic control of propagation effects and the impact of stock-plant age and source was examined in 9 month-old Pinus radiata cuttings. The cuttings investigated were propagated from stock-plants aged between 2 and 5 years, and microcuttings propagated from 12 week old stock-plants. The design included 20 families, with seven clones per family and an average of seven ramets per clone. Five ...

Establishing trees in agricultural bottomlands is challenging because of intense competition, flooding and herbivory. A summary is presented of new practices and management systems for regenerating trees in former agricultural fields in the eastern USA. Innovations have come from improvements in planting stock and new silvicultural systems that restore ecological function more quickly than trad...

This dissertation investigates the main research question: Which classification of innovation explains the heterogeneous timing of revenue realization? Given the significance of financial gain, researchers are recommended to pay attention to whether innovation outcomes result in commercial gains in the short term. Following this notion, a new category of innovation, planting and harvesting, is ...

Water oak is often used in afforestation projects in the Lower Mississippi Alluvial Valley, but its field performance is often poor due to low survival rates and severe top dieback immediately after planting. The poor physiological quality of planting stock may be a contributing factor to this transplanting problem. In this study, cold storage was investigated to increase dormancy status of see...

A mangrove plantation as a Clean Development Mechanism (CDM) project is expected as a sink of greenhouse gases, because of their large CO2 sequestration ability of high primary productivity. The method for estimating the amount of carbon stock after plantation was essential for a planning of a mangrove CDM project. However, there is often no information about tree planting year and planting reg...

An important criticism of bioclimate envelope models is that many wide-ranging species consist of locally adapted populations that may all lag behind their optimal climate habitat under climate change, and thus should be modeled separately. Here, we apply a bioclimate envelope model that tracks habitat of individual populations to estimate adaptational lags for 15 wide-ranging forest tree speci...

INTRODUCTION Ecological restoration is a rapidly growing field of biology. Grassroots restoration activities have a long history and have recently increased dramatically. These are now being supplemented by state and federally sponsored restoration projects reaching tens and hundreds of millions of dollars, like those in the Everglades, Lake Tahoe, and the Sacramento River and Delta. Academic p...

Selecting the proper stock type for reforestation on dry sites can be critical for the long-term survival and growth of seedlings. In this study, we use a novel approach to understand stock type selection on a site where drought was induced with vegetative competition. Three ponderosa pine (Pinus ponderosa Lawson & C. Lawson var. ponderosa C. Lawson) seedling stock types were planted in the fie...
