“…The Michurinsk SAU breeding program was no exception. The first rootstocks bred at the Michurinsk SAU were obtained from 'M8' (East Malling, UK) and local cold hardy cultivars [8]. One of the first obtained rootstocks-'Paradizka Budagovskogo' (later commonly known under the name 'B9') ('M8' × 'Krasniy Shtandart') and '13-14' ('M8' × 'Tayezhnoye')-was widely used in hybridization schemes in the 1950s-1960s.…”

The Michurinsk State Agrarian University (Michurinsk SAU) is one of the leading centers for breeding apple clonal rootstocks. A diverse collection of apple rootstocks, founded in 1930s by V.I. Budagovsky, is maintained at the Michurinsk SAU. In the present study, 87 rootstocks from this collection were analyzed using 18 SSR markers to assess their genetic diversity and relatedness. The detected polymorphism level was rather high compared to the previous estimates of apple rootstock genetic variability. A total of 199 alleles were detected with an average of 11.1 alleles per locus. Among the detected alleles, 67 (33.67%) were rare and 43 (21.61%) were unique. The average PIC value was 0.73, and the expected and observed heterozygosity averaged 0.76 and 0.69, respectively. All the studied accessions except two could be identified with the used marker set. Cluster analysis revealed several groups according to the rootstocks’ pedigrees and genetic origin. Furthermore, Structure analysis revealed two main groups of the studied rootstock accessions. No significant differentiation of the studied sample according to dwarfing ability was detected, while weak differentiation was detected according to leaf color. SSR genotyping data can be used for rootstock fingerprinting and pedigree verification and will facilitate collection management. In addition, data on the genetic diversity and structure of the studied collection may be useful for further development of the Michurinsk SAU rootstock breeding program.

“…In 24 hours after processing and further, daily, on leaves of the same plants, within 5 days took measurements of fluorescence of a chlorophyll and parameters of light scattering. In the latter case used the high-aperture interferometer of shift [11] by which determined intensity (I) and degree of coherence (G) a biological object scattered laser radiation. On these indicators counted the size of the given coherence (G/I), being an important information indicator in the evaluation of the functional condition of the plant tissue [8].…”

“…In the measurement of chlorophyll fluorescence, a nondestructive quantitative diagnostic method was used according to photosynthetic activity parameters, which were expressed in arbitrary units and determined by the dynamic characteristics of the Kautsky curve (Borodin et al 2008). The parameters of slow induction of chlorophyll fluorescence according to the maximal quantum yield of PSII (Fv/Fm) and the actual quantum yield of PSII (Yield), were estimated using a portable fluorometer LPT-5/CF model manufactured in Michurinsk Russia, by Michurinsk State Agrarian University into bio-photonics department (Budagovskaya and Budagovsky, 2015).…”

This work discusses the laser irradiation effects on tomato seeds (Solanum lycopersicum L), regarding the initial plant development, salinity stress tolerance and harvest yield. The aim of this study was to find an optimal pre-sowing laser irradiation treatment to enhance tomato crop.A diode laser with wavelength of 660 nm and power 100 mW was used, 16 treatments were tested by 4 power densities (0.2, 0.4, 2 and 4 mW cm-2) applied during 4 exposure times (15, 30, 60, 120 s) and a control group without treatment. The study was divided into three stages,firstly it was selected an optimal laser treatment (04 mW cm-2, 30 s), in the second stage the optimal laser treatment was evaluated under salinity stress, and finally in the third stage the optimal laser treatment was evaluated on harvest yield. The optimal laser treatment, on the initial plant development enhanced germination by 10%, radicle growth by 19%, and hypocotyl growth by 13%, in comparison to the control. On seedlings under salinity stress, optimal laser treatment promote germination up to 20%, radicle growth up to 23%, and hypocotyl growth up to 12%.According to this study, saline stress inhibits PSII activity in tomato seedlings,whereas optimal laser treatment increased PSII activity around 71%. About greenhouse crop, optimal laser treatment improved mass produced by 26%. The present study shows a path for application ofpre-sowing red laser radiation treatments in tomato seeds to improve development, saline stress tolerance and final production of tomato crop.
