Influence of phytoohormonekinetin on the growth of planttrees of Coffea arábiga L. Grafted on robust pattern in nursery

Abstract

The project tends to achieve the production of higher plants, tolerant to pests and diseases; it was executed in the nursery of the experimental farm of the Southern State University of Manabí, located in the Andil site; with the objective of determining the incidence of phytohormone kinetin in the growth of four varieties of Arabica coffee: Sarchimor 1669, Sarchimor 4260, Pache and red Catuai, grafted on robust pattern. The applied methodology was experimental-factorial of A x B with random block designs with 8 treatments, one for each variety used with hormone and one for each variety without hormone and four repetitions; For the evaluation of the averages, the Tukey test was used at 95% confidence; the following variables were analyzed: height of plants, diameter of plants, length of leaves, number of leaves, leaf width, leaf area, root length, root volume, root weight and vigor of the plants, in a period of six months from January 20, 2017. The results of the arrest at 15 days after the grafting in the four varieties considered determined the following percentages: pache, 98.50%; Sarchimor 1669, 98.00%; Catuai red, 97.75% and Sarchimor 4260, 97.25%. Subsequently we proceeded to quantify the values of the variables based on which it was recommended to strengthen the results obtained by performing other tests of similar characteristics.
