在雅罗斯拉夫国家育种站里,伊拉里奥诺夫制定了禾本科植物的无性杂交方法,就是当幼芽长到1厘米长时,把胚(接穗)嫁接在其他植物的种粒的胚乳上。幼芽在这年令最容易嫁接成功。如果幼芽长到1.5厘米或更多时,则愈合比较困难,或根本不能成功。材料的准备对于无性杂交是很重要的,要选取同年命的幼芽进行嫁接。当把小麦嫁接在黑麦上时,黑麦种子的播种催芽要比小麦晚一晝夜。在进行嫁接时很重要的是接穗和砧木的幼芽鞘粗细(直径)相一致,粗细不相符合常引起分蘖点和叶
In Yaroslavl National Breeding Station, Hiralarov has developed a method of cloning gramineous plants by grafting the embryos (scion) onto the endosperm of the seeds of other plants when the shoots are 1 cm long on. Buds make the easiest grafting success in this year. If the shoots grow to 1.5 cm or more, the healing is more difficult or unsuccessful at all. Material preparation is very important for cloning, to select the same age of the sprouts of grafting. When wheat is grafted onto rye, rye seeds are sown more or less overnight than wheat. It is important during grafting that the sheath thickness (diameter) of the scion and rootstocks is consistent and the thickness does not consistently correspond to the tillering point and the leaf
