Influence of manure in the seedbed and naked seed on germination and vigor of mango rootstock

Abstract

A study on two sowing methods combined to two substracts was conducted in a half-shaded nursery, located at area of the Cerrado Agricultural Research Center - CPAC/EMBRAPA. Four treatments were used: a. Sowing seeds without endocarp into substract with manure; b. Sowing seeds without endocarp without manure; c. Sowing seeds with endocarp into substract with manure; d. Sowing seeds with endocarp into substract without manure (Control). The results obtained demonstrated that the sowing process of seeds without endocarp promoted high percentage and velocity of germination, and excellent uniformity of the seedlings. On the other hand, this treatment permitted to obtain rootstocks of better quality in a shorter time than the other treatments. Manure didn't interfere with the velocity of germination, although has induced a high vigour on the rootstocks at grafting time. There was no correlation between velocity of germination and diameter of the seedlings, but there was a positive correlation with the height of the rootstocks.
