New crops face formidable competition from established crops. Management practices for established crops are well understood, and their productivity gains over time are often spectacular, such as the nearly linear increase in maize yields from 1955 to the present (Troyer 2004). Their long success reflects well-organized research, extension and marketing efforts. For new crops to prosper against...

Pollen-mediated gene flow from transgenic crops is a concern of the scientific community as well as the general public. Current lack is a nondestructive method to measure dynamic (hourly or shorter time period) source pollen release rate (source strength) from these crops. This paper reports an improved method using Rotorod concentration samplers and sticky slides, together with a fast response...
