The phytohormone is crude compound that produce in plant's metabolism,
it can affect plant's cell differentiation, cell division, growth and
affect plant's morphogonesis, abloom, grown up, break off, caducity, dormancy
and bud etc.
Some kinds of phytohormone that often used plant tissuc culture as follows.
The chiefly physiological function of auxin is accelerating cell elongating
and cell division, and abducting injured tissuc face cell to resume division
ability, and accelerating rootage. The auxin can accelerate se division
of the plant too.
The chiefly function of cytokinin is: ①It can accelerate cell division
and expand (it different of the function of auxin that accelerate cell
elongating). ② It abduction bud division. ③ It can restrain tisscu caducity.
The cytokinin dissolves in watery muriatic acid easily. The dissolved
cytokinkn can be adding distilled water, then put it in the icebox to
