ИЗМЕНЧИВОСТЬ ПЛАСТИЧЕСКИХ ПРИЗНАКОВ ЛИСТОВЫХ ПЛАСТИН TRIFOLIUM PRATENSE

VARIABILITY OF PLASTIC TRAITS OF TRIFOLIUM PRATENSE LEAF PLATES

ИЗМЕНЧИВОСТЬ ПЛАСТИЧЕСКИХ ПРИЗНАКОВ ЛИСТОВЫХ ПЛАСТИН TRIFOLIUM PRATENSE

Abstract

Проведен анализ флуктуационной и пластической изменчивости листовых пластин Клевера лугового (Trifolium pratense), сорт Марс, при четырёх видах обработки почвы в условиях 1-го севооборота в адаптивно-ландшафтных системах земледелия. Флуктуационная изменчивость определялась по индексу флуктуирующей асимметрии ФА2, который рассчитывался по нормирующей разности левого и правого признака. Статистическая значимость ФА определялась в 2-х факторном дисперсионном анализе. Пластическая изменчивость – по отношению минимального и максимального значения признака и по коэффициенту вариации этого отношения. Исследуемые выборки отличались по средней величине билатерально симметричного признака. Наибольшее его значение получено при втором способе обработки почвы (комбинировано-энергосберегающий). Этот способ показал повышенное содержание элементов питания (P2O5, K2O, NO3 и свободного азота N2), отсутствие значимой флуктуирующей асимметрии и отрицательную корреляцию между величиной признака и пластической изменчивостью (р <0.05). Третий и четвертый методы обработки почвы (комбинированно-ярусная и противоэрозионная) показали отсутствие отрицательной корреляции между признаков и пластической изменчивостью. Пластическая изменчивость коррелировала высоко положительно с ФА2 во всех выборках, кроме четвертой (r = 0,36). Таким образом, комбинированно-энергосберегающий метод обработки почвы способствовал относительно высокому уровню стабильности развития, развитию крупной листовой пластины с высокой пластической изменчивостью и повышенным содержанием минеральных элементов.

The fluctuation and plastic variability of leaf plates of meadow clover (Trifolium pratense), variety Mars, under four types of tillage in the conditions of the 1st crop rotation in adaptive-landscape farming systems was analysed. The fluctuating variability was determined by the fluctuating asymmetry index FA2, which was calculated by the normalizing difference of the left and right traits. Statistical significance of FA was determined in 2-factor analysis of variance. Plastic variability – by the ratio of the minimum and maximum values of the trait and by the coefficient of variation of this ratio. The studied samples differed in the mean value of the bilaterally symmetrical trait. Its highest value was obtained at the second method of soil cultivation (combined energy-saving). This method showed increased content of nutrition elements (P2O5, K2O, NO3 and free nitrogen N2), absence of significant fluctuating asymmetry and negative correlation between the trait value and plastic variability (p < 0.05). The third and fourth tillage methods (combined tier and anti-erosion) showed no negative correlation between trait value and plastic variability. Plastic variability correlated highly positively with FA2 in all samples except the fourth (r = 0.36). Thus, the combined energy-saving tillage method promoted a relatively high level of developmental stability, development of a large leaf plate with high plastic variability and increased content of mineral elements.
