Dendrolycopodium obscurum, synonym Lycopodium obscurum, commonly called rare clubmoss, [2] ground pine, [3] or princess pine, [4] is a North American species of clubmoss in the family Lycopodiaceae. [5] It is a close relative of other species such as D. dendroideum and D. hickeyi, also treelike.
Within its range, the annual average temperature is 8.5°C, the coldest month average minimum temperature is −0.8°C, and the annual average precipitation is 2,458 mm (2.458 m). [17] In the North Island, mountain pine are found exclusively in montane to alpine habitats and usually between 600 and 1500 m elevation.
HSFs are essential in plants’ ability to both sense and respond to stress. [5] The HSFs, which are divided into three families (A, B, and C), encode the expression of heat shock proteins ( HSP ). Past studies have found that transcriptional activators HsfA1 and HsfB1 are the main positive regulators of heat stress response genes in ...
Growing degrees (GDs) is defined as the number of temperature degrees above a certain threshold base temperature, which varies among crop species. The base temperature is that temperature below which plant growth is zero. GDs are calculated each day as maximum temperature plus the minimum temperature divided by 2, minus the base temperature.
Dacrycarpus dacrydioides, commonly known as kahikatea (from Māori) and white pine, is a coniferous tree endemic to New Zealand. A podocarp , it is New Zealand's tallest tree, gaining heights of 60 m over a life span of 600 years.
Norfolk pine is part of an ancient plant family named Araucariaceae, which was widespread during the Jurassic and Cretaceous periods. Native to the South Pacific, this evergreen can reach 200 feet ...
The bristlecone pine's root system is mostly composed of highly branched, shallow roots, while a few large, branching roots provide structural support. The bristlecone pine is extremely drought tolerant due to its branched shallow root system, its waxy needles, and thick needle cuticles that aid in water retention. [8] Gnarled bristlecone pine wood
