The paper presents the results of a comprehensive assessment of the viability and decorativeness of 20 samples of 17 taxa of the genus Crataegus L. when introduced into the Kola North. The study is one of the stages of a systematic description of the adaptive state of plants of the genus Crataegus when introduced into the conditions of the Far North. The main part of the studied samples are highly decorative quite viable plants that have high winter hardiness, maintain their growth shape, are able to produce germinating seeds, and have attractive inflorescences and fruits. C. chlorosarca, C. chlorosarca f. pyramidalica, C. cuneata, C. dahurica, C. douglasii, C. flabellata, C. laevigata, C. maximoviczii, C. pinnatifida, C. sanguinea, C. x schroederi. C. arnoldiana, C. canadensis and C. foetida are nonviable and undecorative plants. For the introduction of promising species of the genus Crataegus into the landscaping of cities of the Kola Peninsula, preliminary testing is required. Maintaining a highly decorative state is possible while observing the care of woody plants.

Selection and introduction of a new high-quality range of plants that can grow in modern conditions is the main goal of studying plants in the genetic collection of the arboretum of the Russian Research Institute of Fruit Crop Breeding (VNIISPK), which includes more than 300 species, forms and varieties of woody plants. The class of coniferous plants, which makes up 25% of the total number of taxa, is represented by three families and nine genera, one of which is Picea A. Dietr. The analysis of ecological and biological features was carried out for 10 native and introduced plant species of this genus in the collection of the VNIISPK arboretum. All the studied species and forms had high winter hardiness, with the exception of Picea omorica (Pancic) Purcyne. With the loss of decorativeness, the Picea canadensis Britt was damaged by pests; Picea omorica (Pancic) Purcyne. was affected by diseases. Two highly decorative genotypes that are resistant to a complex of adverse environmental factors have been identified for use in landscaping of objects of various purposes in the Orel region: P. abies f. cristata (L.) H. Karst and P. pungens f. glauca Reg. For landscape gardens and parks, it is also recommended to use the P. abies f. virgata (Jacq.) Casp.

Papaya Seeds

Sarcotesta, sclerotesta, endosperm and embryo of fresh and old (0 and 3 years, respectively) seeds of the P.R. 6-65 and P.R. 8-65 papaya varieties were separately analyzed by paper chromatography to determine the presence of natural growth inhibitor that might be responsible for the reduction in germination of papaya seeds during storage. The results showed that in the innermost seed parts (embryo and endosperm) endogenous growth promoters were found while the outermost structures (sarcotesta and sclerotesta) contained inhibitors. Therefore, it is possible that the natural growth inhibitors of this seed might be minimized by removing the sarcotesta (the gelatinous envelope) of the seed, which contains the most endogenous growth inhibitors, plus a careful washing to eliminate the soluble inhibitors of the sclerotesta during the extraction of seeds from the fruits.
