Исследование электрических сигналов в зёрнах пшеницы с различной всхожестью и разработка рекомендаций по построению экспертной системы

Abstract

The use of bioelectric potentials in wheat seeds may considerably reduce the time of germination ability definition. The research stages are as following: 1) seed preparation; 2) metering the bioelectric signals. The shape, levels and variation time of signals should be fixed by glass electrode. The recommendations on the expert system for wheat seeds germination ability determination should be developed. The experimental unit was divided into the following 4 parts: I, II, III, and IV. Two series of experiments were conducted with the germinating ability of 91% and 99%. The coordinates At, AE, Bt and BE were used to evaluate the signal. The comparative analysis was conducted in 2 variants: the seeds of different germination were compared in the different units and compared in the limits of the same germination ability. It was possible to determine the points A and B in Unit I only for the seeds with 99% germination. It may be connected with the place of the Unit in the experimental unit. For the Unit II the points A and B were determined for the germination of 99% and 91%. In Unit II it was possible to use only the point A. In the Unit III only the point A may be used as it was impossible to determine B for the seeds with 99% germination. In the Unit IV the points A and B can be used for the analysis. The comparative analysis of seeds with the same germination in different units shows that the diagrams for the seeds with 91% germination are different depending on the unit, unlike the seeds with 99% germination. The type of bioelectric signals is the same for both germination abilities. The parameters for the expert system for different units are determined: for the Unit I it is point A for 99% germination and the diagram for 91% germination; for Unit II it is point A for both germinating abilities; for Unit III point A for both germinations; for Unit IV points A and B for both germinating abilities.

Использование биопотенциалов в зёрнах пшеницы сократит время определения всхожести. Этапы исследования: 1 — предварительная подготовка зерна; 2 — снятие показателей биоэлектрических сигналов. Необходимо зафиксировать форму, уровни и время изменения сигналов с помощью стеклянного электрода. Нужно разработать рекомендации к экспертной системе для определения всхожести пшеницы. Экспериментальная установка разделена на 4 участка − I, II, III, IV. Было 2 серии экспериментов с зёрнами всхожестями 91 и 99%. Определён общий вид графика биоэлектрического потенциала. При оценке сигнала использовались следующие параметры: координаты точек At, AE, Bt, BE. Сравнительный анализ проводился в 2 вариантах: сравнение зерна разной всхожести в пределах участка, сравнение зерна из разных форм одинаковой всхожести. В форме I определены значения А и В для зёрен всхожести 99%. Предполагается, что это связано с расположением формы в установке. Для формы II определены координаты А и В для всхожестей 99 и 91%. В форме II анализ можно проводить только по координатам А, доверительные интервалы координат В пересекались. В форме III для анализа можно использовать координаты А, координаты точки В невозможно определить для зёрен всхожести 99%. В форме IV для анализа можно использовать координату точек А и В. Сравнительный анализ зёрен одной всхожести в разных формах показывает: графики для зерна с всхожестью 91% имеют различие в зависимости от расположения, для зёрен всхожестью 99% не имеют. Вид биоэлектрических сигналов аналогичен для обеих всхожестей. Определены параметры для экспертной системы: для формы I — значения А для всхожести 99% и вид графика для всхожести 91%; для формы II — значения А для обеих всхожестей; для формы III — значения А для обеих всхожестей; для формы IV — значения А и В для обеих всхожестей.
