I peeked behind the cedars at the edge of the garden, and there was bittersweet nightshade growing with both its purple flowers and those telltale red berries, which are poisonous. I’m usually able to keep this perennial weed at bay by mulching around my cedar trees after pulling it out...
Some of these invasive species are woody in nature (trees and shrubs), and these typically have a past or current horticultural connection. Thus, plant propagators of woody plant species need to remain informed of how plants are identified as invasive and which species are beginning to spread ...
Conifers, or plants with cones such as pine trees, dominate many forests in western North America. The study found that conifers are less likely to regenerate after fires when seedlings face drier climate conditions, especially in low-elevation forests that already experience frequent drought stress...
These insects suck the sap from trees and plants, and for yellow poplar, in particular, they may leave deposits of honeydew behind. The honeydew can lead to mold, and while this does not cause lethal damage, it can be difficult to deal with and treat. The USFS recommends horticultural ...
These essential plants are the biggest on the planet. They make it possible for our insects, birds, and wildlife to survive. Trees reinforce the soil, prevent flooding, reduce wind speeds, store carbon dioxide, cool the air, reduce the temperature in cities, and give us oxygen. ...
Sudden oak death is a disease caused by the microscopic pathogen Phytophthora ramorum that affects trees and plants in coastal California and a small area of southwest Oregon. Although it is usually found in forest areas, it can also affect redwoods in urban areas that run up to undeveloped wil...
A pine tree isany coniferfrom thePinusgenus of plants, and this group includes more than 120 types of pine trees worldwide. These are evergreen conifers,woody plantsthat bear seed cones and which have bundles of needles rather than the broad leaves commonly found on deciduous trees. ...
Neighbor-joining (NJ) trees were inferred with the BioNJ algorithm80 using PhyML v2016011581 with the following parameters: 1000 bootstraps, 100 seeds, and correction for multiple substitutions. A majority consensus tree was created and visualized in Dendroscope v3.7582. Statistics and reproducibility...
and ranged from seven to nine orders of magnitude in CFU g–1plant fresh weight (Fig.3b). The median plant weight was between 13.0 and 68.1 mg (Fig.3c; Source Data), with axenic-infected plants showing the lowest median plant weight (18.4 and 13.0 mg for experiment 1 and 2, ...
