Influence of biometric parameters of black nut fruit (Juglans nigra L.) on seed germination

Goal. To establish the influence of quantitative biometric parameters black nut fruit on dormancy its seeds. Methods. The results research were processed according to generally accepted methods in agriculture, plant growing, statistics. Field — collect fruits, measuring weight determine parameters, spectrometric, mathematical-statistical carry out analysis variance and statistical processing assess their reliability. Results. relationships between Juglans nigra L. size, weight, thickness shell, magnitude force splitting, mass nucleus for germination. A positive correlation was found yield kernel endocarp, effort split shell determined by mass. According 3-year research, inversely proportional dependence indicators amount splitting endocarp has been proved, which strength seed germination depends smaller harder it is germinate. stratification process humidity increases up 5 times, reduces during determined. Conclusions. It that endocarp; from shows a with kernel; 1 g directly nucleus. germinate; moisture content (almost times) general changes stratification, resulting decrease splitting.
