Abstract

There has been a substantial increase in the 1970s in the international movement of cut flowers and cuttings and to a lesser extent potted flowering and foliage plants (5, 6, 35, 58). This increase has been mainly related to the establishment of new production areas in Central and South America (especially Colombia), Israel, Kenya, and more recently, Mexico. Not all of the increased floral product movement in the 1970s was due to new production areas as established floral production centers in The Netherlands, Italy, and Canada have also increased their international floral trade activities.

Abstract

A computer simulation was developed to analyze the economic feasibility of over-tree misting based on the interrelationships of daily temperature, bud development and corresponding effects of low temperature on apple (Malus domestica Borkh.) and peach (Prunus persica (L.) Batsch) flower bud kill in Ohio. Utilizing historical temperature data from 1940 through 1972, a revised model for estimating rest and bud development was constructed and the probability and extent of bud kill was simulated. Model validity was tested utilizing 1973-1976 temperature data. Using the 1940 to 1976 period, it was evident that the risk of substantial losses in revenue was reduced when over-tree misting was employed in all Ohio locations. Potential economic returns of the over-tree misting technology were greater for peaches than apples. Need for this risk reduction varies geographically in Ohio for apples and to a lesser extent for peaches.
