Re: [nafex] Re: chilling hours

I dont know how to figure chilling hours ....we certainly had 4 months 
completely below freezing, much below 0. I'd say an absolute minimum would 
be 3000 hours below freezing and probably a lot more. I'll call around and 
see if there is actually some gov. agency that actually records such info.? 
any idea where to learn the chill req. of manchurian apricot?  Mn. Del
