Nemesia Root Hair Response to Paper Pulp Substrate for Micropropagation

Figure 1

Nemesia roots cultivated on agar (a), paper pulp (b), and control plant (c) from greenhouse. (a1) Root hair of nemesia plant cultivated on agar medium. Note the strongly modified cellular morphology even at higher magnification in (a3). (a2) Root cap of nemesia cultivated in agar medium. No root cap is clearly identifiable. (b1) Root hair structure in nemesia root cultivated on paper pulp. (b2) Root cap of nemesia cultivated on paper pulp. Note the quiet similar structure to the control plant from greenhouse (c2). (c1) Root hair structure of the nemesia root cultivated in peat in greenhouse conditions. (c2) Root cap of nemesia cultivated in greenhouse conditions in peat. (d) Root cap of nemesia cultivated in sorbarod.
