Air roots are normal in Phalaenopsis and other epiphyte orchids. Epiphytes grow on other plants, such as trees in a tropical rainforest. Unlike terrestrial orchids that root in the earth, epiphyte orchids grow above the ground, using their roots to attach themselves to tree branches. ...
As soon as the flowers wilt and begin to drop off the stem (called a “spike”), it can be cut. Prune the spike off at the base, being careful not to accidentally snip any leaves or roots as well. Phalaenopsis orchids are an exception: they will often produce more flowers from the ...
if its expression level satisfies the following criteria: (1) "Average_root" (the average expression level of the two biological replicates of the roots) of the transcript should be five times or more than "average_stem" (the average expression level of the two biological replicates of the s...
equestris tissues (leaf, flower, stem and root), we assembled transcription fragments, and 93% (root) and ∼97% (leaf) of the assembled sequences could be mapped to the genome assembly with 90% identity and 90% mapping coverage (Supplementary Table 6). Thus, the coverage of the ...

Orchid rapid propagation initiated in the 1960s when Morel utilized stem-tip tissue from Hybrid Cymbidium, cultivating it on a cytokinin-containing medium. This led to the formation of protocorms, which subsequently differentiated into roots and leaves, resulting in the first virus-free orchid plant...
Pseudobulb propagation is best performed early in the spring before new bulbs appear. When repotting the orchid, locate the main underground stem. This should have a number of pods along its length. You need to slice the stem into pieces, each with two or three pseudobulbs, and the first...

Will an orchid grow a new stem? Orchids will grow new stems, fortunately. You can propagate a new Phalaenopsis or Vanda orchids from stem cuttings. ... You can also expect a flower spike to grow back after cutting it down when its blooms die. ...
6. It has been hypothesised that radiations are facilitated by entering a new ecological niche with little or no competition from similar species (ecological opportunity), and the genetic potential allowing the necessary adaptations to evolve (genetic variation), ultimately leading to rapid bursts of...
