PROTEIN MARKERS OF LOUISEANIA ULMIFOLIA (FRANCH.) PACHOM. PLANT AND ITS INTERGENERIC HYBRIDS
A comparative study of electrophoretic markers of reserve seed proteins in the poorly studied Louiseania Ulmifolia (Franch.) Pachom and its intergeneric hybrids with micro-cherry, cherry-plum and apricot, has been carried out. The markers of Louiseania Ulmifolia seedlings in M2, its hybrids with micro-cherry (in M1, M2) and cherry-plum were studied in culture (in Badakhshan, Central Asia; in Orenburg (OSAU); in the Crimea – Yalta, the Nikitsky Botanical Garden. The hybrids of the above plant with apricots and cherry-plum were studied under the conditions of Western Tyan-Shan (Mid. Asia, Kyrgystan and Uzbekistan – the city of Tashkent). Moreover the markers of local cherry-plum varieties growing in the Crimea and Western Tyan-Shan have also been studied. The Louiseania Ulmifolia was introduced in the town of Orenburg about 25 years ago from the subtropical zone of the mountainous central Tadzhikistan (Surkho ridge) by the author of the article. It is found that under the conditions of Central Asia the polypeptide specters, containing 52–62 components in the plants under study, grown both in natural and cultivated environments, are at 25% more compound than the cultivated plants in the Crimea and in Orenburg (42–45 components). It is pointed out that the following predominance of poor intensity components (1 point) has been typical: 71–95% in Central Asia (natural and cultivated plants), 59–65% in other above mentioned regions (cultivated plants). These data confirm the prior obtained results on the changeability of outer characters in the almond family plants growing under the conditions of mountainous Central Asia. It is for the first time that detailed data on the composition of polypeptide specters in all the studied plant varieties and their hybrids are suggested.
