SANTOS, Maria Herbênia Lima Cruz; SANTOZ, Emanuel Ernesto Fernandes and LIMA, Giuseppina Pace Pereira. Preservative solutions in beehive ginger post-harvest. Cienc. Rural [online]. 2008, vol.38, n.8, pp. 2354-2357. ISSN 0103-8478. http://dx.doi.org/10.1590/S0103-84782008000800041.
The objective of this research was to study some physiological post-harvest aspect of beehive ginger inflorescences grown in the lower middle San Francisco river basin. Flower stems just harvested were submitted to different treatments (distilled water; 75mg L-1 of silver nitrate - AgNO3; 1000mg L-1 of cobalt chloride - CoCl2; 5mg L-1 de GA3 - Progibb® and 10mg L-1 of 6-benzylamino purine - BAP), in an environment with controlled temperature and humidity, for 15 days. The post-harvest life was monitored from grading scale, fresh weight, and consumption of the preservative solution. The treatment with silver nitrate was the most efficient to keep the vase life of beehive ginger, however due to its toxity, the use of GA3 is recommended.
