what are 3 extracting methods for flavour and oddor?
Definition

  • Compression: crushing oil glands. == Most citrus oils
  • Infusion:  plant is placed in hot water and the cell membrane ruptures and water captures the essence.
Term
what are the different methods of vegetative propagation?
Definition
  • Leaf-petiole cutting: young plant cut. =African violet
  • Lateral Vein cutting: monocot leaves are cut in two inches at right angles. Streptocarpus
  • Leaf Slashing: cut from undersides of leaf veins. =Begonia
  • Foliar Embryos: independent plantelets are formed along the margins of the leaves. 
  • Stem cutting: the stem must survive until they root. common practice. ==house plants
  • layering: SIMPLE-> bending a branch down, apply a hormone rooting power. ==Rhodedendron.  AIR-> upward cut thru a node, roots will develop ==rubber plants.
  • Grafting/Budding: a cutting, short length of stem of one plant is attached to another the one w the root is the rootstock. both meristemic tissues unite.==apple plantations.
