Different methods have been used for the extraction of bio-chemicals, including plant and bacterial products affecting
morphological and physiological processes related to seed development.Such discoveries in combination with the use of exogenously applied plant hormones (Lian et al., 2000) have led to more rapid advancement of the field and some interesting findings (Miransari and Smith 2009). Plant hormones are interactive and hence the production of each may be dependent on the production of other hormones
