Screening of different Fe (II) and Fe (III) complexes at the stage of rhizogenesis in vitro of gooseberry plants

Abstract

During clonal micropropagation of the Pink-2 (Rosovy-2) gooseberry cultivar at the stage of rhizogenesis, the efficiency of modification of the media with mineral salts according to Quoirin-Lepoivre (QL) was shown by replacing iron, which is standardly used in the form of FeSO4×7H2O together with Na2EDTA, with chelated forms with carboxyl-containing ligands Fe(III)-EDTA and Fe(III)-DTPA and the organophosphate complexone Fe(II)-HEDP. On the 45th and 60th days of subculturing, the distribution in descending order of the impact of chelate iron compounds on the rooting rate of the studied gooseberry plants was as follows: Fe(III)-EDTA>Fe(III)-DTPA> Fe(II)-HEDP> Fe(III)-EDDHA>Fe(III)-HEDP. On the 60th day of subculturing in the best variants of the experiment, the rooting rate of gooseberry microcuttings of cultivar Pink-2 was 86.7-100% compared to 60% in the control variant.

The Role of Chelate Coordination Compounds of Biogenic Metals in the Vital Activity of Plants

“…On the 45th and 60th days of subculturing, the distribu tion in descending order of the impact of che late iron compounds on the rooting rate of the studied gooseberry plants was as follows: Fe(III)EDTA>Fe(III)DTPA> Fe(II) HEDP> Fe(III)EDDHA>Fe(III)HEDP. On the 60th day of subculturing in the best variants of the experiment, the rooting rate of gooseberry mi crocuttings of cultivar Pink2 was 86.7100% compared to 60% in the control variant [74].…”

“…Applying to the soil and spraying with solu tions of complexonates of microelements have a positive effect on the yield of many crops [66][67][68][69][70][71][72][73][74][75][76][77]. For example, treatment with man ganese, iron, copper, etc.…”

“…Complexes of 3dmetals with EDDS are en vironmentally safe biostimulants and positive ly affect the yield of plants (apple trees, straw berries, legumes, cabbage, buckwheat, alfalfa, etc.) [72,[74][75][76][77]. Fe[S,S']EDDS was evaluated as an ironcontaining fertilizer in growing ca lendula [78].…”

SYNTHESIS AND STUDY OF NANO-SIZED COMPLEX OF Fe(III) WITH ETHYLENEDIAMINEDISUCCINIC ACID

“…For example, complexes of metals with ethylenediaminedisuccinic acid have an antimicrobial effect against fungi and bacteria [8] and an antiviral effect against cytomegalovirus [9]. They can be used in homeopathic doses on all types of soil for any plants, or as feed additives for animals, without harming nature [10][11][12].…”

Screening of different Fe(III) and Fe(II) chelate complexes in clonal micropropagation technology of highbush blueberry (Vaccinium corymbosumL.)

“…Earlier studies have already been conducted in the study of iron chelate complexes on fruit and ornamental crops in vitro [16,17,18,19,20]. There have also been studies on blueberry plants [21,22], but we decided to expand the number of chelate complexes tested.…”
