Construção e avaliação de um protótipo de máquina coletora de anteras

Abstract

CONSTRUCTION AND EVALUATION OF AN ANTHER COLLECTOR PROTOTYPE MACHINEABSTRACT -An anther collector prototype machine was projected and built. Its performance was evaluated by comparisons between the use of the prototype and the traditional manual method, both for showy and nonshowy peach-tree flowers (Prunus persica). The study was accomplished in August 2011 using a completely randomized experimental design, arranged in a bi-factorial scheme (2 collection methods x 2 flower forms), with 12 repetitions, each consisted by 30 flowers. The prototype proved to be faster in the anther extraction time without losses in the pollen quality, even harvesting anthers with higher fillet amounts and discarding a higher quantity of anthers than the manual method.
