ARTIFICIAL VS NATURAL Natural is when nature does it( generally seen in perennial plants), and artificial is with a little help from man.
Natural Propagation includes: Corms: ( each year more and more corms grow around the original…must be separated or they will choke) gladiolas and crocus Tubers: ( come from underground stems) potatoes Stolons: ( horizontally above ground stems with tiny leaves from which new plants grow) strawberries are an example Scaly bulbs: ( similar to corms but much larger) onions, garlic, daffodils Tip layer: arching shoots that ultimately touch-down onto the soil ex. Blackberries Root sprouts( suckers): The roots of most plants produce cytokinins. As these accumulate in the roots, the cytokinins induce shoot formation. Near the base of the shrub, a new shoot will begin to grow. Ex. Red raspberries and most bushes
Leaf cuttings : clone plants by taking a piece and putting it in water or moist soil Stem cuttings : faster than leaf cutting. Place stem piece in water and soon it’s sprout and you plant it. Tissue Culture: designed to make thousands from one small clipping. Clipping is placed into a tissue culture containing nutrients and water. Sprouts quickly. Grafting/ Budding : both are means of asexual propagation that join different plant parts as one. There are many types and the type depends on the reason for grafting. Reasons may be: develop a plant with inadequate root systems stronger stem of one grafted to another for better fruit or flower production **** IN THE NAME OF SCIENCE… NEW AND BETTER FRUITS, VEGGIES AND FLOWERS
