Abstract
Изобретение относитс к сельскому хоз йству и может быть использовано в селекции растений. Цель изобретени - упрощение способа и сокращение затрат. Дл отбора форм земл ники, устойчивых к PHYTOPHTHORA CACTORUM, се нцы земл ники с 2-3 листочками непосредственно перед пикировкой погружают кратковременно в суспензию мицели и зооспор возбудител болезни, которую получают смывом с 14-дневной культуры изол та, выделенного из ризома больного растени . Дл приготовлени 500 мл инокулюма используют смесь с 10 чашек Петри. Про вление заболевани начинаетс на 4-5 день. При максимальном развитии болезни осуществл ют отбор устойчивых форм. 2 табл.The invention relates to agriculture and can be used in plant breeding. The purpose of the invention is to simplify the process and reduce costs. In order to select forms of PHYTOPHTHORA CACTORUM resistant earthlings, earthlings with 2-3 leaves just before the picking are immersed briefly in the suspension of the mycelium and zoospores of the pathogen of the disease, which is obtained by washing away from a 14-day isolate culture isolated from the rhizome of a diseased plant. To prepare 500 ml of inoculum, use a mixture of 10 Petri dishes. The onset of the disease begins on day 4-5. With maximum development of the disease, selection of resistant forms is carried out. 2 tab.
Description
Изобретение относитс к сельскому хоз йству и может быть использовано в селекции земл ники.The invention relates to agriculture and can be used in the selection of earthlings.
Цель изобретени - упрощение спо- iсоба и сокращение затрат.The purpose of the invention is to simplify the process and reduce costs.
Способ осуществл ют следующим образом .The method is carried out as follows.
Се нцы земл ники с 2-3 насто щими листочками непосредственно перед пикировкой погружают кратковременно в суспензию мицели и зооспор Jhyto- phthora cactorum, предварительно полученной смывом с 14-тн дневной культуры изол та,.вьщеленйого из ризома ув дающего растени земл ники. Дл приготовлени 500 мл инокулюма используют смьш с 10 чашек Петри. По вление заболевани начинаетс уже-на 4-5 день. Через 4-5 недель практически все восприимчивые растени погибают .Sonts of earthlings with 2-3 leaves, immediately before picking, are immersed briefly in a suspension of mycelium and zoospores of Jhytophthora cactorum, previously obtained by washing with a 14-day diurnal isolate, derived from a rhizome of a planting earth dredger. Remove 500 ml of the petri dish to prepare 500 ml of inoculum. The appearance of the disease begins as early as 4-5 days. After 4-5 weeks, almost all susceptible plants die.
Испытано несколько вариантов заражени .Tested several variants of infection.
Эффективность различных способов заражени Phytophthora cactorum се нцев земл ники показана в табл..The efficacy of various methods of infecting Phytophthora cactorum of seedlings on earth is shown in Table.
Более молодые растени (например, с 1 насто щим листочком) неудобны дл работы из-за малых размеров и повьшенной чувствительности к механическим повреждени м, в.результате .чего гибнет до 25-30% растений, среди которых могли бы оказатьс и высокоустойчивые к заболеванию. Более - взрослые хуже перенос т пересадку даже без заражени из-за заметного пог вреждени корней при выкопке. Younger plants (for example, with 1 true leaflet) are inconvenient to work because of their small size and increased sensitivity to mechanical damage, resulting in up to 25–30% of plants dying, among which could be highly resistant to disease. . More adults are less tolerant of transplanting, even without infection, due to a noticeable damage to the roots during digging.
Результаты заражени фитофторозом се нцев земл ники разного возраста показаны в табл. 2.The results of infection with late blight of seedlings of earthlings of different ages are shown in Table. 2
Таким образом, предлагаемый способ позвол ет уже на ранних стади х отбраковать восприимчивые к фитофто- , розному ув данию растени , что исклю (ЛThus, the proposed method allows, at early stages, to reject plants susceptible to phytotophthalic, rosacea, which I exclude (L
