Изобретение относитс к области селекции растений и предназначено дл ранней диагностики важнейшего показател качества урожа винограда - сахаристости год.The invention relates to the field of plant breeding and is intended for the early diagnosis of the most important indicator of the quality of a grape harvest - sugar content year.
Существующие способы оценки сортов винограда по их сахаристости основаны на непосредственном анализе сока год и могут быть выполнены только на плодонос щих растени х . Была показана слаба пр ма коррел ци между концентрацией клеточного сока листьев в первой половине вегетации и сроком созревани (раннеспелостью) винограда.The existing methods for evaluating grape varieties by their sugar content are based on a direct analysis of the juice a year and can only be performed on fruit-bearing plants. A weak correlation between the cell sap concentration of the leaves in the first half of the growing season and the maturity (early maturity) of the grapes was shown.
Цель изобретени - проведение диагностики до вступлени растений в плодоношение. The purpose of the invention is to conduct a diagnosis before the plants enter fruiting.
Дл этого определ ют концентрацию клеточного сока листьев, причем пробу берут в период 1-15 суток конца п той фазы и 1 - 10 суток начала шестой фазы вегетации и о сахаристости суд т по сравнительным показател м концентрации клеточного сока.For this, the concentration of the cell sap of the leaves is determined, and a sample is taken in the period of 1–15 days of the end of the fifth phase and 1–10 days of the beginning of the sixth phase of the growing season and sugar content is judged by comparative indicators of the concentration of cell sap.
Пробы листьев отбирают в утренние часы с определенных узлов побега. Дл определени используют части листовой пластинки, наход щиес между главными жилками.Samples of leaves are taken in the morning with certain escape nodes. For determination, the parts of the leaf blade located between the main veins are used.
Достаточен общий вес отобранных листьев одного растени около 2-3 г с суммарной поверхностью около 80 см. Определение концентрации отжатого клеточного сока листьев провод т с помощью лабораторного рефрактометра .The total weight of the selected leaves of a single plant is about 2-3 g with a total surface of about 80 cm. The concentration of the pressed cell sap of the leaves is determined using a laboratory refractometer.
На основе результатов проведенных сравнительных определений дл отбора растений винограда с наибольшей потенциальной сахаристостью выдел ют те экземпл ры, которые имеют наибольшую концентрацию клеточного сока листьев.On the basis of the results of the comparative determinations made for the selection of grape plants with the highest potential sugar content, those specimens that have the highest concentration of leaf cell sap are isolated.
Предмет изобретени Subject invention
Способ диагностики потенциальной сахаристости год винограда, отличающийс тем, что, с целью проведени диагностики до вступлени растений в плодоношение, определ ют концентрацию клеточного сока листьев, причем пробу берут в период 1 -15 сутки конца п той фазы и 1 -10 сутки начала шестой фазы вегетации и о сахаристости суд т }ю сравнительным показател м концентрации клеточного сока.A method for diagnosing the potential sugar content of a grape year, characterized in that, in order to diagnose before the plants enter fruiting, the concentration of the cell sap of the leaves is determined; vegetation and sugar content are judged by comparative indicators of cell sap concentration.
