Resumo
Its objective is to evaluate the seedlings growth disseminated by grafting and cutting
and to characterize gas exchanges and chlorophyll fluorescence a in conilon coffee.
The experiment was conducted at the seedling production vivarium of Incaper‟s
Experimental Farm in Marilândia city in Espírito Santo. In the grafting, seedlings from
seminiferous propagation of Coffea canephora species, „Robusta Tropical 8151‟ were
used as rootstocks, and as graft, six clones Conilon „Vitória Incaper 8142‟. The
cutting was done with six clones used in the grafting. The experimental design was in
randomized blocks with twelve treatments and five repetitions composed by twelve
seedlings. After 130 days the grafting read the variables of gas exchanges and
chlorophyll fluorescence a after 150 days means of variables were evaluated and
they were compared by Scheffé test with a probability of 5%. The grafted seedlings
were superior in all growth characteristics. Significant differences weren‟t detected to
gas exchanges in none of the cutting and grafting contrasts and the same hasn‟t
occurred to chlorophyll fluorescence a parameters and when the study considered
the maturation stage the materials showed no differences among them.
