Results of studies of the ascorbic acid content of leaves of Polemonium coeruleum L. in 13 natural and 13 cultivated cenopopulations are presented. The ascorbic acid content of plants from the majority of natural cenopopulations (76.2 to 221 mg%) is lower than in the plants of cultivated cenopopulations (143.2 to 228) mg%. The average interpopulation ascorbic acid content in nature is (148&plusmin;13) mg%, and in culture
Distribution of 20-hydroxyecdysone within Serratula coronata L. plants was studied at different growth stages. High levels of 20-hydroxyecdysone were detected in young actively functioning plant parts. It was shown on the example of Serratula coronata and Rhaponticum carthamoides (Willd.) Iljin that the ecdysteroid distribution pattern depended on bio-morphological peculiarities of plant species. The significance of ecdysteroid distribution pattern within plants for studding of biochemical aspect of plant-insect interaction was shown.
The time course of the sum of water-soluble polysaccharides and galactomannanes in the seeds of various years of collection from some representatives of tribes Galegae (Bronn) Torr. Et Gray and Trifoliae (Bronn) Benth. Of Fabaceae family has been studied by standard methods. In long stored seeds of the Fabaceae studied, the content of the mantioned substances is rather stable.
Mannose-containing reserve polysaccharides galactomannanes in seeds of eight species of Trifolium L. (Fabaceae) have been studied. The content of water-soluble polysaccharides and galactomannanes, and one of basic phytochemical characteristics
The ontogenetic variations of flavonoid (flavonol) content in Artemisia dracunculus L. were investigated. The peak of flavonoid content in the introduced Novosibirsk and the wild Berdsk populations was noted during flower budding and fruiting phases. A gradual replacement of methyl flavonols by common flavonols
The analysis of biochemical characters in Pentaphylloides fruticosa (L.) O.Schwarz (bush cinquefoil, fam. Rosaceae) introduced in the forest-steppe zone of West Siberia shows that the plants of various ecotypes grown in identical conditions have a considerable intra- and interpopulation variability. The obtained results show that the plants of different ecotypes have a high level of variability in biochemical characters
The composition and contents of flavonoids in the leaves of species of the genus Myosotis L., sections Sylvaticae, Alpestres and Myosotis from various growing places have been studied. The flavonoid profiles of the species studied by us are characterized by a considerable similarity. Irrespective of the collection site, in all the species of the section Sylvaticae three common components are present. In species of the sections Alpestrers and Myosotis,there are four common components. In all the specimens studied, irrespective of the species, the dominant flavonoid component is F3. Flavonoid content of species M. krylovii and M. imitata from various regions are characterized by a very high variability.
The chemical composition of fruits of 33 zoned and prospective varieties and hybrids of Hippophae rhamnoides L. in conditions of Novosibirsk region forest-steppe zone were investigated. The mass of fruits, dry soluble matter, soluble sugars content, organic acids, sugar-acid index, ascorbic acid, oils and carotenoids were studied. The values of coefficients of biochemical traits variability for the many years studies (1981
A biochemical evaluation of non-traditional fodder plants Pentaphylloides fruticpsa (L.) O. Schwarz and P. Parvifolia (Fisch. Ex Lehm.) Sojak growing in different ecogeographical zones of the Mountainous Altai and under introduction conditions has been made. It is established that the plants of these species with respect to the main indicators of nutritious compounds are not inferior to, and with respect to some of them, e. g. raw fat content, and at some times with respect to protein, are above, many fodder leguminous plants and cereals.
