GM vs . Non - GM : A Survival Analysis of Hybrid Seed Corn in the US
We investigate the survival of new seeds in the US hybrid corn seed market between 2002 and 2007. Controlling geographic location, we find that product characteristics and market structure variables have significant impacts on the hazard of corn hybrids. The results also suggest spill-over effects of learning among close substitute seeds, and a spatial pattern of survival: seeds in the center r...

متن کامل[Comparison of carotenoid components between GM and non-GM papaya].
We compared the carotenoid profile in GM papaya (Sunup) line to that of a non-GM one (Sunset). First, to identify major carotenoids in papaya, large-scale extraction was carried out with methanol. HPLC analyses of the methanol extracts revealed that both papayas mainly contained 5 pigments and no apparent difference was observed in the HPLC profiles. On the basis of LC/MS data and photodiode-ar...
