Summary We evidence the apical dominncia through the method using three plants planted of clius blumei, having the plant de4 the 5 pairs of leaf, and continue cutting the way apexes to leave 3 pairs of leaf for plant. We completely cover the cut with a folder of lanolina I contend 1000 mg/L of acid naftalenactico. In the first plant we involve meristema apical with plastic, being moored with string in caule. After 14 days we get in the comment the formation of small roots. In as the experiment we repeat the procedure but with one it plants under climatization control and in it we place pure lanolina, next to a plant testifies without the apical cut leaving both in the interior of a vegetation house. To the 14 days of the beginning of the experiment we made comments we affirm that the controlled plant for ambiencia does not present brotaces in caule.

But in the third test we made with gilete transversal incisions to 3 mm of apises, being the plant dealt with NAA and lanolina, mounted in water and I assist with it of a microscope we made 3 countings I around number of it of cell of the fabric of the exchange layer, and we after identify to 14 days of the beginning of the procedure the presence of bigger proliferation of cells in the superior areas of the vascular exchange. Praising the apical domain on the third experiment. Introduction The development of the cultivated plants is controlled, beyond the genetic and ambient factors, for physiological or hormonais factors. During the cycle of development of the cultures, these organic composites influence in the physiological processes, as the growth of apicais sprouts the work that I carried through spreads out the apical dominncia through consideration for favorable ambincia and disponibilizao of hormones, that are deposited in the apexes. The plant that we use to carry through this method is colius blumei contends the presence of lanolina and acid naftalenactico.
