‘Isabel’ Grape Treated with Abscisic Acid in Different Maturation Stages

Authored by Sergio Ruffo Roberto

Isabel grape is one of the main cultivars used for juice processing, but presents deficiency in anthocyanins, pigments responsible for the color. Thus, an alternative for increasing the color is to promote synthesis of this compound, which can be accomplished using growth regulators, like abscisic acid (ABA). This work aimed to evaluate anthocyanins and polyphenols concentration in berry and juice of ‘Isabel’ grape treated with abscisic acid in different maturation stages. Statistical model used was a randomized block design with seven treatments and five replications: control; S-ABA 400mgL-1, applied 7 days before véraison (DBV); S-ABA 400mgL-1, applied at véraison (V); 7 days after véraison (DAV); S-ABA 400mgL-1, applied 7DBV + S-ABA 400mgL-1 35 days after the first application (DAFA); S-ABA 400mgL-1, applied at V + S-ABA 400mgL-1 35DAFA;
and S-ABA 400mgL-1, 7DAV + S-ABA 400mgL-1 35DAFA. S-ABA application increases anthocyanins concentration, color variables, and acceptability of juices in sensory analysis, without affecting polyphenols concentration. Two applications of S-ABA 400mgL-1 provide best results regarding the increment of berries and juice color of ‘Isabel’ grape.

Traditional Knowledge on Mushroom consumption habits of Amhara region in four selected districts; - Mecha, Fogera, Bahir Darzuria and Zege

Authored by Birhanu Gizaw

Population growth coupled with increase in demand for food, domestication and scientific cultivation of wild edible mushroom is alternatives means to alleviate food shortage and malnutrition.The purpose of this study was to assess traditional wild mushroom consumption habit in four selected districts of Amhara region, Mecha, Zege, Fogera and Bahir Dar Zuria. In this study 115 adult individuals 81 males & 34 females were selected and used as information source. Data were collected using structured open and close ended questionnaire, interview as well as personal observation. The study result indicated that (90.43%) of the Mecha, Zege and Bahirdar Zuria Woreda residents have awareness about wild mushroom consumption and its various benefits. About 9.57% of the residents do not have an awareness especially Fogera district.Wild mushroom collection was donemainly from cultivated farmland (65.21%) followed by termite nests (14.78%), uncultivated land (13.04%), forest vicinity (5.21%). All family members, children, women and men were involved in mushroom collection.
