Abstract

This paper describes the design, fabrication, commissioning and use of a CALibration source Insertion System (CALIS) in the DarkSide-50 direct dark matter search experiment. CALIS deploys radioactive sources into the liquid scintillator veto to characterize the detector response and detection efficiency of the DarkSide-50 Liquid Argon Time Projection Chamber, and the surrounding 30 t organic liquid scintillator neutron veto. It was commissioned in September 2014 and has been used successfully in several gamma and neutron source campaigns since then. A description of the hardware and an excerpt of calibration analysis results are given below., Comment: 21 pages, 11 figures

Abstract

Actinidia arguta (Sieb. et Zucc.) Planch. ex Miq. or mini kiwi is a valuable fruit and berry crop. Nowadays, it is important to use biotechnological methods to propagate rare cultivars of A. arguta successfully introduced in temperate climate. The purpose of the study was to optimize the techniques for cultivating promising cultivars of A. arguta at the micropropagation stage to develop an effective method for its clonal micropropagation. The studies were carried out in 2022 at the Plant Biotechnology Laboratory of the Tsitsin Main Botanical Garden of the Russian Academy of Sciences. Promising cultivars (‘Solnechny’, ‘Zolotaya Kosa’ and ‘Taezhny Dar’) bred at the Federal Horticultural Center for Breeding, Agrotechnology and Nursery, as well as selective male form of A. arguta were the objects of the current study. During the research process, the influence of genetic features and the composition of the culture medium on the regeneration capacity of A. arguta was established. 6-benzylaminopurine, meta-topolin and thidiazuron were used as a plant growth regulator. It was found that on the Quorin and Lepoivre (QL) culture medium, in the case of an increase in the concentration of 6-benzylaminopurine from 0.5 to 1.0 mg/l, the length of microshoots decreased in ‘Solnechny’ (from 18.8 ± 0.7 to 12.4 ± 0.6 mm) and ‘Taezhny Dar’ (from 22.8 ± 1.0 to 19.1 ± 1.1 mm). At the same time, the use of the studied 6-benzylaminopurine concentrations contributed to an increase in the multiplication rate in most cultivars, but no significant differences were found. Simultaneously, the effectiveness of 0.5 mg/l meta-topolin in QL medium, compared with 0.5 mg/l 6-benzylaminopurine and 0.5 mg/l thidiazuron, was established. During culturing on a medium with meta-topolin, in most cultivars, both the length of microshoots (from 21.2 ± 1.1 to 31.2 ± 1.1 mm, depending on the cultivar) and the multiplication rate (from 9.0 ± 0.7 to 14, 8 ± 0.8) increased. The addition of thidiazuron to QL medium caused various morphological abnormalities in A.arguta explants.
