The technology of canopy plastic mulching has been widely used in citrus orchards for protecting fruit trees from cold damage. Understanding the spatio-temporal dynamics of plastic-mulched citrus (PMC...
Foliar water uptake (FWU) has been reported for different species across several ecosystems types. However, little attention has been given to arid ecosystems, where FWU during dew formation or small ...
上个世纪90年代,北美灌木柳育种计划在纽约州启动,经过30多年的杂交、选育以及在美国中、北部的区域试验,选育了一大批高产、高抗的灌木柳栽培品种,目前很多品种在美国已商品化生产。在北美纽约州、宾夕法尼亚州等地,灌木柳被广泛用于工业污染地、垃圾填埋场的植物修复、公路防风雪篱以及生物质能源生产。尽管国际上在柳树重金属污染修复方面做了大量研究,筛选出很多对重金属具有高积累、耐性以及转移的品种,但是重金属积...
In this study, we investigate seedlings of Quercus castaneifolia C.A. Mey, from five different provenances for the research on leaf and crown morphological variations in relation to a light gradient ...
The aim of this work was to suggest a reliable method for distinguishing between diploid and tetraploid taxa of the genus Betula Linnaeus, based on leaf measurements. In total, 97 individuals from 6 ...
Forest soils in western parts of Iran are being degraded by inappropriate management. The soil organic carbon (SOC) stock was dominantly affected by this type of degradation. On the other hand, SOC is...
Genetic diversity between 110 individuals from 6 elm populations (Ulmus minor, U. glabra and U. laevis) was determined using ISSR markers. Altogether 73 ISSR markers were evaluated with the average ...
Our research was concerned with a description of the influence of variability in average temperatures on the height growth of selected young populations of spruce in the Krkonoše Mts. Several pop...
Climate change is expected to influence the distribution and population dynamics of many insect pests, with potential severe impacts on forests. Spruce bark beetle Ips typographus (L.) (Col.: Curculio...
In the years 1987–1993 research aimed at the qualitative and quantitative composition of insects inhabiting the cones of Norway spruce (Picea abies [L.] Karst.) was carried out in the area of the Tatr...
The aim of research was to find out the variability of spruce (Picea abies [L.]) Karst.) wood compression strength limits in the direction parallel to grain. The wood strength was examined using sampl...
Based on a map of potential natural vegetation (PNV), actual vegetation was studied in the Mramor locality (106.4 ha). A total of 188 relev閟 were examined using stratified random sampling. A compariso...
The paper valuates the differences in the selected characteristics of the assimilation apparatus of beech transplants growing in various light conditions of blue spruce small pole stage in the Jizersk...
Two exemplary black spruce (Picea mariana [Mill.] B.S.P.) provenance trials were analyzed using traditional and spatial techniques. The objective was to find out possible differences between these app...
The study was aimed to assess the integral value that determines wood properties − wood density at a moisture content of 0% and 12%. The wood density was researched in a sample tree with the pre...
