NAVARRO, Marlen  and  LEZCANO, J. C. Effect of drying method on the longevity and quality of seeds from Bauhinia purpurea.: II. Storage in cold-storage room. Pastos y Forrajes [online]. 2008, vol.31, n.1, pp.1-1. ISSN 0864-0394.

The combined influence of different drying methods, the storage conditions and the physiological age of seeds from Bauhinia purpurea, on their germinative capacity and quality was determined. The treatments for drying were: A) in the pods; B) artificial; and C) under sunlight. The moisture content (MC), germination and viability of the seeds were determined during the 12 months of storage in the cold-storage room. For the information processing multivariate analyses were used. In A the highest value of the germinative capacity (98,67%) was observed in the first evaluation, as in B (100%), where the differences between months were minimal in the whole study. In C the germinative capacity was 79,33% at 12 months, which represented a quantitative increase of longevity of the seeds with regards to A. The germinative process in A, between 0 and 9 months of storage, was completed 9 days after the test started, while in the other evaluations it occurred after 6 days. Between the seeds of B and C a similar performance was observed, only with the difference that the germinative potential could be expressed after 6 days in B at 0 and 2 months; in C at 0, 1, 2 and 11 months; while in B germination began after 6 days for 9 and 10 months. It is concluded that the treatments essayed in this work can be applied to bauhinia seeds, although the best results were obtained when using silica gel (B).
