概括
这项研究评估了从英国进口的Quercus robur对植物健康的风险,确定了八种关键的害虫. 预计最常见的是Coniella castaneicola,对于盆栽植物来说,对害虫免费的信心很高.
科学领域:
- 植物健康风险评估
- 植物病理学 植物病理学
- 昆虫学 昆虫学是一门学科.
背景情况:
- 欧盟委员会委托对高风险植物进口进行风险评估.
- 来自英国的Quercus robur (树) 植物被评估为潜在的害虫引入.
- 具体的进口类别包括鞭子,幼苗,裸根植物和盆栽植物.
研究的目的:
- 对从英国进口的Quercus robur相关的植物健康风险进行科学意见.
- 根据风险评估相关性的定义标准来评估特定的害虫.
- 评估英国提供的风险减轻措施的有效性.
主要方法:
- 根据相关性特定标准对所有相关害虫的评估.
- 选择八种关键害虫进行进一步的风险评估,包括欧盟检疫害虫和不受监管的害虫.
- 风险减轻措施的评估和有关无害虫可能性的专家判断.

Adaptations that Reduce Water Loss
25.6K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Lumber Defects
124
Lumber defects, which can affect both the appearance and structural integrity of wood, include a variety of growth and manufacturing flaws. Growth defects such as knots and knotholes occur where branches were once attached to the tree trunk, with knotholes forming when these knots fall out. Other natural defects include decay and insect damage, which compromise the wood's strength and durability.
