The main goal is to identify elite materials adapted to the current bunching onion growing areas in Colombia, with tolerance to diseases and fitted to farmers and market preferences.
Interestingly, bunching onion leaves are extremely popular in the Asian cuisine and their nutritional properties are very well known .
On the other hand, pseudostem length and diameter are extremely important traits in the Colombian bunching onion markets, as the widest genotypes are marketed on local fresh markets, middle size ones are preferred by grocery stores, and the thinnest ones are used by the processing industry.
In the pre-SOX period (1993-2002) there is no evidence of bunching
. The frequency distribution of public float data shows no discontinuities around $75 million.
Die geometry influence in bunching process of steelcords (SC) will be found in the contribution (Wright, 201l; Tittel & Zelenay, 2009).
At the same time it was supposed that the better conditions of lubrication contribute to lower dies wear and also better surface quality of wire, which is very important for bunching.
Remark: Two indicators of workability were measured in bunching process (1st indicator was count of fractures per production quantity at the bunching of SC, 2nd indicator was quantity of produced wire which was separated into scrap because of too often fractures occurrence).
