ФГБУН Институт биологических проблем криолитозоны СО РАН, Россия,677980, Якутск, пр. Ленина, 41 Работа посвящена изучению влияния механохимического порошка из древесной зелени пихты (МПН) на морфогенез картофеля in virto. В исследовании использовались безгормональные питательные среды (МС, ½ В5, ½ ЛС) на которые помещали микрочеренки предварительно полученных асептических растений. Наблюдение за морфогенезом растений проводили на 15 и 30-ый дни, оценивали частоту развития побегов, высоту растений, число листьев, частоту ризогенеза, число корней и их длину. The article gives the results of the study of an effect of mechanochemical powder of wood green of Abies (MPA) on potato morphogenesis in vitro. The study involved the hormone-free nutrient mediums (MS, ½ B5, ½ LS) for growing microcuttings from preliminary obtained aseptic plants. Plant morphogenesis was observed on the 15 th and 30 th days. At that, the number of developed shoots, plant height, leaves number, rhizogenesis rates, root number and length were estimated. MPA appeared to have the regulatory effect on morphogenesis of potato microcuttings. Based on 1 Работа выполнена в рамках госзадания ИБПК СО РАН на 2017-2020 гг. № АААА-А17-117020110056-0
Ecological tests of improved in vitro plants - potato regenerants of promising and zoned in Central Yakutia varieties have been carried out on cryogenic flood plain fibrous saline soils. To conduct a field experiment, clones adapted to the soil (2019) and their tuberous offspring (2020) were planted at the end of May. It was revealed that the most resistant to open ground conditions were regenerants of the Krasavchik variety (survival rate - 28.0 %); the least adapted variety was Vasilek (1.0 %). It has been established that among improved zoned varieties the most tolerant to arid conditions of vegetation (hydrothermal coefficient 0.4) and more productive (average tuber weight 213.9 g) was the Adretta variety. High index of tuber safety (100.0±5.0 %) was observed in Adretta variety (37 pcs.) and promising varieties Riviera (18 pcs.), Triumf (40 pcs.) and Rodrigo variety (16 pcs., 94.1±4.7 %). Zoned variety Vasilek (12 pcs., 80.0±4.0 %) and promising variety Assol (77.3±3.9 %, 17 pcs.) had no statistical difference in these indexes. The safety of Krasavchik variety tubers was 69.1±4.0 % (241pcs.). Zoned variety Rozard (65 pcs., 55.6±2.8 %) and promising Ilona variety had the same tuber safety. Minimum level of tuber safety was observed in Velina variety (18 pcs., 33.3±1.7 %).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
