Description
Изобретение относитс к сельскому: хоз йству и может быть использовано дл определени полевой всхожести сем н по лабораторным показател м.The invention relates to agriculture: a farm and can be used to determine the field germination of seeds by laboratory parameters.
Целью изобретени вл етс повы шение точности определени полевой всхожести сем н в лабораторных усло ВИЯХ за счет вы влени их потенциаль ных качеств.The aim of the invention is to improve the accuracy of determining the field germination of seeds in laboratory conditions by detecting their potential qualities.
Пример. Подготавливали ложе рулон дл сем н. Дл этого нареза ли фильтровальную бумагу (20x50 см), смачивали ее в приготовленном раство-- ре сахарозы с осмотическим давлением 12 атм концентрацией 14% и на нее раскладывали 4 порции по 50 шт. испытываемых сем н на линию, прочерченную посередине. Бумагу скатывали в рулон, ставили в стекл нные банки, сверху накрывали стеклом и проращивали в термостате при 25°С (+1°).Example. A bed was prepared for seeds. To do this, filter paper (20x50 cm) was cut, it was moistened in a prepared sucrose solution with an osmotic pressure of 12 atm with a concentration of 14% and 4 portions of 50 pieces each were laid out on it. test seeds on the line drawn in the middle. The paper was rolled up into a roll, placed in glass jars, covered with glass on top and germinated in a thermostat at 25 ° C (+ 1 °).
