Production of soursop seedlings under methods of overcoming dormancy and doses of manure
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2017, Vol 12, Issue 2
Abstract
The objective of this study was to evaluate the effect of different methods of overcoming dormancy and doses of manure in seeds and soursop (Annona muricata L.) seedlings. The work was developed in a greenhouse at the CCTA / UFCG. Four doses of bovine manure (0,0; 15; 30 and 45%) were used and to overcome dormancy were used: T1 - Intact seeds as a control; T2 - Scarification on the opposite side of the micropyle, using a nº 80 sandpaper; T3 - Side cut of the tegument, with the aid of a stylet; T4 and T5 - Immersion in gibberellic acid (GA3) for 96 hours, at 0.5 and 4.0 mg L-1, using four doses of bovine manure (0.0, 15, 30 and 45%) instead of the soil. The 5 x 4 factorial scheme was used with four replicates of two plants per plot. The pre-germination methods did not differ in the emergence and were not very representative for the growth of graviola seedlings, especially the treatments using gibberellic acid (GA3) in a period up to 60 days after sowing. Doses of manure up to 45% in substitution to the soil cause negative effect on the growth of soursop seedlings regardless of the method of overcoming dormancy.
