Canopy Development, Photosynthesis, and Vegetative Growth as Affected by Apple Rootstocks

Journal of the American Pomological Society, 1991
Fisheye photographs were taken in 1988 from bud break to terminal bud formation under the canopies of ‘Starkspur Supreme Delicious’ apple trees on nine rootstocks in the 1980 NC-140 cooperative planting in Simcoe, Ontario. Each photograph was computer-analyzed for the percentage of sky cover.

Herbivore species asynchrony underpins multitrophic stability across plants, herbivores and predators

Journal of Animal Ecology, EarlyView.
Across a grassland food web, multitrophic stability was most closely associated with herbivore species asynchrony. By identifying herbivores as a key source of temporal buffering between plants and predators, this study shows that intermediate consumers can play a central role in stabilizing the complex food web.

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Burrow Persistence and Spatial Distribution of Federally and State‐Protected Gopher Tortoise (Gopherus polyphemus) Populations in Southwest Alabama

Animal Conservation, EarlyView.
The gopher tortoise (Gopherus polyphemus), a keystone species and ecosystem engineer, has declined by ~80% over the past century due to primarily habitat loss. In a 28‐year resurvey of federally protected Mobile County and state‐protected Baldwin County, we found tortoise populations persisted at ~59% and ~31% of sites, respectively, with significant ...

Effect of selected rootstocks on vegetative growth of apple trees [PDF]

, 2012
Eestis on hetkel palju amortiseerunud õunaaedasid, mis vajavad uuendamist. Õunakasvatuses on oluline viljade kõrge kvaliteet ja hooldustööde lihtsustamine. Sellepärast uuritakse kloonaluse mõju õunapuude kasvule ja saagile.

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Effect of rootstock on plum (Prunus domestica) transplant quality [PDF]

, 2016
Pookealused võivad mõjutada taimed kasvu, saagikust ja kohanemisvõimet erinevate klimaatiliste tingimustega. Ploomisortidel on erinev kasvutugevus ning seetõttu on pookealuse mõju taime kasvule erinev.

Optimizing culture media for in vitro proliferation and rooting of Tetra (Prunus empyrean 3) rootstock [PDF]

, 2015
The enormous demand for new rootstock genotypes in Prunus spp. makes us to use micropropagation as an unavoidable propagation method. Therefore, the study on micropropagation of a new semi-dwarf vegetative rootstock namely Tetra (Prunus empyrean 3) was ...

Low Rates of Kaolin in Different Application Periods Reduce Diaphorina citri Population and Huanglongbing Incidence in Commercial Citrus Orchards

Journal of Applied Entomology, EarlyView.
ABSTRACT Huanglongbing (HLB) is the most destructive citrus disease worldwide, and it has been disseminated by the Asian citrus psyllid Diaphorina citri, the vector of the causing agent Candidatus Liberibacter asiaticus. Although processed kaolin reduces psyllid infestation, long‐term field data from commercial orchards are limited.

A Systematic Map to Identify Knowledge Gaps on a Vector of Citrus Greening Diseases: The African Citrus Triozid, Trioza erytreae (Del Guercio, 1918) (Hemiptera: Triozidae)

Journal of Applied Entomology, EarlyView.
ABSTRACT Globally, citrus production areas are threatened by greening diseases, also known as Huánglóngbíng (HLB), associated with phloem‐limited gram‐negative species of the genus Candidatus Liberibacter. Those pathogens are transmitted by either the Asian citrus psyllid, Diaphorina citri Kuwayama 1908 (Hemiptera: Psyllidae), or the African citrus ...
