USE OF MILCAP® SUBSTRATES FOR IN VITRO ROOTING AND COMING OUT OF PLANTS OBTAINED BY MICROPROPAGATION

P. Brochard
Micropropagation is speading more and more. The number of plants to which this technique is applied increases day after day, with a definite trend to the ligneous ones : fruit-trees, forest-trees, ornamental nursery plants.

However, between the success of an in vitro micropropagation technique in the research laboratory and its application in an industrial laboratory, a good many problems both technical and economic remain.

Among these problems, we may mention :

  • the difficulty in obtaining good quality rooting for some plants
  • the difficulty of acclimatization.

Let us quote BONGA (1) who says " In many tissue culture cloning programs, one of the most difficult problems is transfer of propagules "

  • the problems of cost and manpower.

The use of the synthetic porous substrate Milcap, for rooting allow a better and more rapid rooting than in agar. The functional roots, which have many hairs are not disturb by transplanting which is carried out by potting up the fibers plug with the asked plant.

So Milcap plugs ease many of the problems of industrialization of micropropagation and many allow mechanisation which is being worked on.
