Hydrolysis Of

IAA, IAN, accelerator α, and an ether-insoluble growth substance (designated as 'A') were found in alcohol extracts of healthy inflorescences of Brassica napus L. and in smaller amounts in the malformed, parasitized inflorescences produced by plants infected with Albugo Candida (Pers. ex Chev.) Kuntze. The total activity of diseased extracts (≡ 915 μg IAA/kg fresh weight) was only 61% of that of healthy ones. IAN accounted for approximately 86% of the total activity in both extracts. Brassica is thus a good source of IAN. Both IAA and IAN were identified by their chromogenic reactions, ultraviolet spectra, and Rf values in two solvent systems. Alkaline hydrolysis of 'A' produced an ether-soluble, Ehrlich-positive spot with the same Rf value as IAA. The results are discussed briefly.

Positive Heterosis

Highly significant positive heterosis was found for root length, diameter and fresh weight in F1 hybrids derived in a seven-parent diallel cross of commercially available cultivars of Brassica napus L. var. napobrassica Mill. Significant general combining ability and specific combining ability effects and a preponderance of additive gene action were also noted for root length, diameter and fresh weight. The inheritance of these three traits is thought to be conditioned by additivity at the majority of loci and partial dominance at the remaining ones. Heritability estimates ranged from 0% for dry matter to 26% for root diameter.

Aim. The study of possible unintended biochemical peculiarities of newly obtained herbicide-resistant canola (Brassica napus L.) plants expressing the lox-dependent BAR gene was the aim. Methods. Total soluble protein content, total free radical scavenging activity, and superoxide dismutase activity have been investigated using Bradford’s, DPPH, and nitroblue tetrazolium assays, respectively. Fresh weight of plants grown on media with or without phosphinothricin was also measured. Results. The antioxidant activity of leaf extracts of untransformed plants under in vitro growth condi-tions had no significant differences in comparison with ones of phospinothricin-resistant plants in the third generation. No significant changes in parameters investigated were observed in transgenic plants cultivated on media with herbicide addition compared to ones grown on media without it. Fresh weight and total soluble protein content were similar in transgenic and untransformed canola plants under growth without phosphinothricin. Conclusions. Lox-dependent BAR gene introduction and expression resulted in no significant differences in leaf antioxidant activity in transgenic canola plants comparing to untransformed controls.Keywords: Brassica napus, antioxidant activity, DPPH, glufosinate, superoxide dismutase.

Отмечена роль Н. И. Вавилова в организации исследований исходного и селекционного материала по биохимическим признакам, определяющим пищевые, кормовые и технологические качества сельскохозяйственной продукции. Выделен перспективный материал для создания сортов рапса с улучшенными пищевыми, кормовыми и технологическими характеристиками; выявлен характер зависимости признаков качества масла от погодных условий (температура, количество осадков и др.). Изучены 50 высокоэруковых (ВЭ) и 40 низкоэруковых (НЭ) линий ярового рапса (Brassica napus L.), выращенных в условиях Ленинградской области в 2012 – 2015 гг. Содержание масла и влажность в семенах определяли методом инфракрасной спектрометрии. Жирнокислотный состав (ЖКС) масла изучали с помощью газожидкостной хроматографии с масс-спектрометрией. Установлено содержание доминирующих жирных кислот для ВЭ и НЭ образцов, а также характер влияния погодных условий на ЖКС масла, в том числе на состав его отдельных фракций. Для ВЭ образцов установлена достоверная отрицательная корреляция (r = –0,96) между содержанием эруковой кислоты и температурой воздуха и достоверная положительная (r = 0,96) с количеством осадков в первую декаду июля. Для НЭ образцов установлена достоверная отрицательная зависимость между содержанием эруковой кислоты и средней температурой воздуха в мае. Выделенные образцы с высоким содержанием олеиновой (61,4 %) и низким линолевой (7,4 %) кислот можно рекомендовать для получения безэруковых сортов рапса, масло которых пригодно для длительного хранения. Контрастные по содержанию эруковой кислоты образцы будут использованы для создания сортов ярового рапса пищевого и кормового назначения, а также для производства биодизеля.
