Erwinia amylovora, the causal agent of fire blight, was first reported in Kyrgyz orchards 2008 and, within a few years, disease has spread throughout most northern part country. As blight expanded and penetrated new areas, it also reached unique ecosystem constituted by Arslonbob wild walnut–fruit forests South Kyrgyzstan. Here, we present results field surveys nearby gardens Jalal-Abad region ...
It is important to propose the correct decision for culling and replenishing seedlings in factory seedling nurseries improve quality of save resources. To solve problems inefficiency subjectivity existing traditional manual replenishment seeds, this paper proposes an automatic method discriminate early growth condition seedlings. Taking watermelon plug as example, Azure Kinect was used collect ...

In fruit and shade tree nurseries, there is a need to count and measure caliper for trees frequently so as to have an accurate inventory sufficiently before harvest since disease, pests and climate can change the yield from year to year. In some tree nurseries it is common practice to count the entire stock three times a year and to caliper them once a year. Both tasks are very labor intensive,...
Sawfishes (Family Pristidae) constitute one of the most threatened families of marine fish, and substantial management efforts are required to stabilize and recover their populations worldwide. Philopatry is common in marine animals, including sharks and rays, and can be a key driver of population structure, which in turn determines the most appropriate scale required for effective population a...
In forest nurseries, irrigation management becomes more complex as different seedlings of tropical species, with architectures, are grown close to each other. this context, there gaps in knowledge about the physiological responses species mean leaf angles when subjected depths. Thus, work aimed analyze whether affect efficiency and, consequently, tree seedlings. Six were submitted three depths ...
Phytophthora ramorum, the cause of sudden oak death on oak and ramorum blight on woody ornamentals, has been reported in ornamental nurseries on the West Coast of North America from British Columbia to California.
