APPLE ROSETTE DISEASE IN NORTH CAUCASUS PLANTATIONS

abstract 1552001001 issue 155 pp. 1 – 12 31.01.2020 ru 198
The article presents the results of a study of the apple tree rosette disease found in a collection garden and having a viral nature. The rosetting has typical signs of manifestation. Sick plants develop narrow small chlorotic leaves. Rosettes of leaves on the upper cervical and lateral shoots are formed as a result of the convergence of internodes. The spread of the rosetting in the planting reaches 10-11 %. The prevalence of viral disease varies among the 44 varieties of apple trees of different ecological and geographical origin. So, the lesion of rosetting was noted on single trees in the varieties of Gala Redi Red, Fujiko, Red Free, etc., and it was a complete defeat in the variety of Piros. A different degree of the manifestation of the disease on the trees was established: from partial manifestation on individual shoots, to aggressive damage to the entire crown of the tree. On young trees bearing fruiting (3-4 years from planting), the rosetting reduces the yield of apple trees by 36 %, ¼ part of the fruits on the trees are small in size compared to the fruits of healthy trees. The infectious nature of the rosetting is confirmed by the transfer of the disease on the most affected Piros variety using summer budding

IMPACT OF GROWTH REGULATORS WHICH WERE NOT USED EARLIER IN CLONAL MICROPROPAGACTION ON MICROSHOOTS OF PLUM IN VITRO

abstract 1151601065 issue 115 pp. 1038 – 1045 27.01.2016 ru 840
The article presents results of the assessment of the efficiency of non-hormonal preparations which were not earlier applied in culture in vitro with high physiological activity (the preparations received by production of furfural, and also derivatives and compositions of organic acids) during regenerations of microshoots of plum, comparison of their influence with influence of growth regulators which are traditionally used in clonal micropropagation. These experimental preparations were received when processing waste of agricultural production. In this work we used: technology of clonal micropropagation of plants of in vitro, statistical data processing by method of the dispersive analysis. The objects of researches were microshoots of plum of a Stanley variety. We have established that on mediums with the preparations "Universal", sodium succinate, potassium succinate, amber acid, L-1 the large, intensively colored plum microshoots develop surpassing control (medium with BAP of 1 mg/l, IBA of 0,1 mg/l, gibberellic acid of 0,5 mg/l) in morphometric parameters. Thus, the preparations "Universal", sodium succinate, potassium succinate, amber acid, L-1 in concentration of 4,0 mg/l proved as the growth factors which are favorably influencing on plantlets’ regeneration and a qualitative condition of microshoots of plum

THE INFLUENCE OF THE PLUM POX POTYVIRUS (PPV) ON THE CONTENT OF PIGMENTS, PROTEIN, LIGNIN, WATER IN TISSUES OF LEAVES OF PRUNUS DOMESTICA

abstract 1271703029 issue 127 pp. 432 – 441 31.03.2017 ru 471
The results of the study of physiological and biochemical parameters of plum plants, changing when infecting plants Plum pox potyvirus (PPV) are shown. It was found that the infected leaves at the stage of full development of the content chlorophyll a reduced by 30 % in variety Stanley and by 6 % in Kabardinskaya rannaya, chlorophyll b in less than 49 % at Stanley, 37% in Kabardinskaya rannaya, carotenoids are less than 22 % in the variety Stanley and by 11% in the variety Kabardinskaya rannaya . Leaves infected with the virus pox (PPV), in comparison with not infected, the amount of protein were decreasing: in the variety Stanley by 21 %, in the variety Kabardinskaya rannaya by 28 %. In the period of active growth of the leaves change in the content of pigments and protein is more intense. The content of lignin in the tissues of leaves, infected with the virus pox (PPV), in comparison with not infected in the variety Stanley was below on 13 % and in the variety Kabardinskaya rannaya - 8 %. The total content of water of infected tissue on the stage of a full-time development is reduced in patients leaves as compared with not infected 11 % in the variety Stanley and by 1 % in the variety of Kabardinskaya rannaya. Throughout the period of development of foliage studied parameters vary depending on the variety
