Use of testas and gravitational mass for the classification and seed quality of coffee (Coffea arabica L.)
Various quality parameters were evaluated in seeds of coffee (Coffea arabica) with or without testas classified according to size using sieves of 22/64 (8.73 mm), 20/64 (7.94 mm), 18/64 (7.14 mm) and 16/64 (6.35 mm). Some of the seeds with testas retained in the 22/64 sieve were also classified using a gravitational table as light, intermediate and heavy seeds. The parameters evaluated were 1000-seed weight; germination at 15, 30 and 40 days; and length of the primary root. Seeds of the same size with testas produced seeds varying in size when the testas were removed. The heavy and intermediate seeds exhibited greater germination than the light seeds, suggesting that the gravitational table can be a reliable tool for determining good-quality seeds.
