1-triacontanol derivatives

The invention relates to plant growth regulators, that is, to compositions influencing the growth of plants. The compositions of the invention contain as active agent a 3,6-diamino-acridine N-glycoside of the formula (I) ##STR1## and/or its acid addition salt of the formula (II) ##STR2## in which formulae at least one of R.sub.1 and R.sub.2 stands for an .alpha.- and/or .beta.-(D)- and/or .alpha.- and/or .beta.-(L)-glucosyl, -galactosyl, -mannosyl, -xylosyl, -arabinosyl, -ribosyl, -6-desoxyglucosyl, -6-desoxygalactosyl, -ramnosyl, -maltosyl, -2-acetamido-2-desoxyglucosyl, -lactosyl, -cellobiosyl, -genciobiosyl or -laminaribiosyl group and the other one represents either a hydrogen atom or one of the enumerated sugar groups;

Plant growth regulators

The invention relates to novel aminoacridine-.alpha.,.beta.-(D)- and -(L)-N-glycoside derivatives, the salts thereof and to a novel process for the preparation of such compounds and salts. The novel compounds have the formula I ##STR1## wherein R is hydrogen or a group of the formula II ##STR2## wherein n=0 or 1, p=1 or 2, A.sup.-p is an anion, preferably halogenide, R.sup.1 is hydrogen or a methyl group and
