A new possibility of improving common bean tolerance to frosts with Cropaid NPA
Dr. Roman Hołubowicz, M.Sc. Magdalena Frąckowiak
Poznań Agricultural University
Common bean has been one of the most important vegetable crops in Poland. In 2006, the total area of commercial bean domestic production was over 30, 000 hectares. It is a warm-season crop and therefore hardly tolerates both cold and freezing temperatures. Reportedly, early bean pods forced in April and May under unheated, plastic tunnels sell well and therefore get good wholesale market price. Their production, however is limited due to lack of cold tolerant cultivars. There is though another way to solve the problem: spray the plants with a compound to improve their tolerance to low temperatures.

The paper presents preliminary results of the application of biological chemical CROPAID which extends ecological dormancy of fruit trees and intensifies the esistance of trees to low temperatures. The experiments were performed at the site of Preljinsko Brdo, the trial field of Fruit Research Institute, on species of plum (cvs Opal, Valor, Valjevka, Čačanska Lepotica, Čačanska Rodna, Stanley, California Blue) and peach (cvs Madeleine Pouyet, Red Heaven, Sprin Gold, Baby Gold). The trees were treated with 0.5% solution of the chemical in three replications over the growing period (March 10,20,31, 2008) and were subsequently exposed to low temperatures (- 4 oC) for two hours. The effect of the applied chemical was monitored by identifying the level of flower damage in studied trees by the fluorescent microscope OLYMPUS BX61. The effect of the chemical (the lowest damage) has been evidenced in cvs Valjevka and Red Heaven. Similarly, somewhat lower damage has been observed in cvs Opal,
