The process of freezing tolerance through cold acclimation is a two-stage mechanism: [4] The first stage occurs at relatively high subzero temperatures as the water present in plant tissues freezes outside the cell. The second stage occurs at lower temperatures as intercellular ice continues to form.
Big sagebrush is a coarse, many-branched, pale-grey shrub with yellow flowers and silvery-grey foliage, which is generally 0.5–3 metres (1 + 1 ⁄ 2 –10 feet) tall. [3] A deep taproot 1–4 m (3 + 1 ⁄ 2 –13 ft) in length, coupled with laterally spreading roots near the surface, allows sagebrush to gather water from both surface precipitation and the water table several meters beneath.
Salvia officinalis, the common sage or sage, is a perennial, evergreen subshrub, with woody stems, grayish leaves, and blue to purplish flowers. It is a member of the mint family Lamiaceae and native to the Mediterranean region , though it has been naturalized in many places throughout the world.
Non-diapausing insects can sustain brief temperature shocks but often have a limit to what they can handle before the body can no longer produce enough cryoprotective components. The common fruit fly. In addition to improving insects' survival during cold temperatures, cold hardening also improves the organism's performance. [9]
The foliage is aromatic, especially when crushed, [10] with a fragrance described as sage-like, [13] a blend of sage and lavender, [14] or like turpentine. [15] The flowering season of S. yangii can be as long as June through October, [6] although populations in some parts of its range, such as China, may bloom in a much more restricted period. [8]
Today, sage, specifically the white sage variety native to southern California and northern Mexico, is environmentally threatened—not only as a result of climate change, but also due to ...
Salvia cacaliifolia, the blue vine sage or Guatemalan sage, is a species of flowering plant in the family Lamiaceae, native to the mountains of Chiapas, Mexico, and in Guatemala and Honduras, at 1,500–2,500 m (4,921–8,202 ft) elevation.
Californian black sage grows in the coastal sage scrub and lower chaparral plant communities. It occurs from sea level to 1,200 m (3,900 ft) elevation. [ 2 ] Black sage is able to grow on a variety of different soils, including sandstone , shale , granite , serpentinite , and gabbro or basalt .
