A new lectin was purified from tubers of Arum maculatum L. by affinity chromatography on immobilized asialofetuin. Although this lectin is also retained on mannose-Sepharose 4B, under the appropriate conditions free mannose is a poor inhibitor of its agglutination activity. Pure preparations of the Arum lectin apparently yielded a single polypeptide band of approximately 12 kD upon sodium dodec...

Cocoyam tubers were subjected to two processing methods (fermentation and parboiling) and milled into flour. The samples were stored at 25°C, 35°C, and 45°C and analyzed at 2 weeks interval for 8 weeks for their nutritional, functional, and pasting properties. Data obtained were subjected to multiple analysis of variance. Storage period and its interactive effect with the processing methods had...

Symbiotic relations are present in the nature and can contribute to success of organisms involved. Endophytic fungi live within leaf tissues without causing any harm host plant, some them be a defense mechanism against attack by leaf-cutting ants. Ants genus Atta known as ants have an obligatory association with fungus Leucoagaricus gongylophorus, cutting pieces leaves bringing back colony fung...

The effects of blanching time and temperature on the sensory and textural properties of frozen cocoyam strips were studied for cocoyam varieties. The most preferred variety after sensory evaluation was blanched at 90°C for 5 min, reproduced, and frozen at a temperature of -18°C for storage studies over a period of 12 weeks with Irish potato as control. Sensory evaluation and instrumental textur...

In the present investigation attempts were made to estimate genetic parameters for yield and its components in 315 genotypes of cocoyam collected from thirteen aroid growing districts. Plant height, petiole length, petiole breadth, leaf number, leaf length, leaf breadth, LAI, Inflorescence length, peduncle length, spathe length, spathe breadth, corm length, corm breadth, cormel number, cormel l...
