Pineapple . The tops of pineapples can become pineapple plants of their own if given the right amount of water and protected from frost. Sparks said he cuts the top of the pineapple off just below ...
Crown sprouting is the ability of a plant to regenerate its shoot system after destruction (usually by fire) by activating dormant vegetative structures to produce regrowth from the root crown (the junction between the root and shoot portions of a plant). [1] These dormant structures take the form of lignotubers or basal epicormic buds.
A pineapple pit requires a huge amount of fresh manure, and manual labour to maintain the temperature of the central trench. [6] The introduction of steam ships meant that the pineapple pit became obsolete, as it was cheaper to transport fruit from overseas than to grow them under special conditions in the UK. In 2012 the cost of growing a ...
The long-lived Pseudotsuga macrocarpa (bigcone Douglas fir) forms epicormic shoots both in response to fire damage and as a means of forming growth on existing branches. The epicormic branching pattern has been observed to six iterations. [11] [12] Pseudotsuga macrocarpa showing branch regeneration after a crown fire through epicormic shoots ...
In crown fire regimes, pines have evolved traits such as retaining dead branches in order to attract fires. These traits are inherited from the fire-sensitive ancestors of modern pines. [ 6 ] Other traits such as serotiny and fire-stimulating flowering also have evolved for millions of years. [ 6 ]
Fire exclusion has resulted in a declining reproductive output, and thus population size, of some species of pyrogenic plants. [3] Additionally, evidence suggests that fires that occur outside of normal seasonal burn times (typically summer months) can have negative repercussions on pyrogenic flowering plants, including lower flowering and seed production when compared to fire-exposed plants ...
High-severity fires will burn into the crowns of the trees and kill most of the dominant vegetation. Crown fires may require support from ground fuels to maintain the fire in the forest canopy (passive crown fires), or the fire may burn in the canopy independently of any ground fuel support (an active crown fire).
Longleaf pine (Pinus palustris) is a pyrophile, depending on fire to clear the ground for seed germination. [4] The passage of fire, by increasing temperature and releasing smoke, is necessary to raise seeds dormancy of pyrophile plants such as Cistus and Byblis an Australian passive carnivorous plant. Imperata cylindrica is a plant of Papua ...
