ประโยคมือถือ
  • In asexual reproduction, a propagule is often a stem cutting.
  • In sexual reproduction, a propagule is a seed or spore.
  • Propagule formation is or is not a type of asexual reproduction?
  • Without propagule pressure the number of invasive species incorporated would be unpredictable.
  • Propagule pressure plays an important role in species invasions ( Groom, 2006 ).
  • The mature propagule then drops into the water, which can transport it great distances.
  • Cryptococcosis is believed to be acquired by inhalation of the infectious propagule from the environment.
  • Buttonwoods grow 39 to 46 feet tall but do not produce a true propagule in Florida.
  • A study noted by Colautti showed the correlation between propagule pressure and invasion success ( 2006 ).
  • When the scion or propagule grows in the same branchlike way, it is called plagiotropic growth.
  • Once a propagule is ready to root, its density changes so the elongated shape now floats vertically rather than horizontally.
  • In most studies a direct relationship is observed, the higher the propagule pressure the higher the success of the invasion.
  • In horticulture, a "'propagule "'is any plant material used for the purpose of plant propagation.
  • Although the exact nature of the infectious propagule is unknown, the leading hypothesis is the basidiospore created through sexual or asexual reproduction.
  • The whole idea of plants controlling the rate of passage of a propagule, like a seed, is a wonderful, open question.
  • One type of propagule is the ungerminated spores, which must percolate through the soil beyond the reach of light in order to germinate.
  • Once a propagule is ready to root, it will change its density so that the elongated shape now floats vertically rather than horizontally.
  • After 3 to 6 months, when the propagule is mature, it drops into the water where it can then be transported great distances.
  • Once germinated, the seedling grows and forms a propagule ( a seedling ready to go ), which can produce its own food via photosynthesis.
  • He measured three common species of mangroves in Panama, these species showed an intraspecific variation of propagule size, and were disposed to attacks from larval insects.
