Today in discovery came to know about a technique by which we can propagate number of trees by limited sources , Trees, trees and trees can save us from Global warming , on the name of which we wasted millions of dollars in 2009United Nations Climate Change Conference held at Copenhagen.
Well artificial and encapsulated seeds are the somatic embryos covered with a protective gel. Gel in encapsulated seeds acts as seeds coat and artificial endosperm provides nutrient.
Embryos coated with sodium alginate and nutrients solution are dipped in calcium chloride solution, Calcium ions induce rapid cross linking of sodium alginate to produce small beads, each containing encapsulated embryos. Encapsulated seeds can be maintained in a viable state till they are planted.
Test of the growth vigor of beads by planting in soil or soil amended with pesticides, out of the other chemicals tested , a polyethylene oxide(Polyox WSR-N75) has good encapsulated property. Polyox coated embryos kept in dry condition and then allowed for germination at suitable conditions. Recently, production of encapsulated seeds by encapsulation of somatic embryos in Eucalyptus species has been reported .
