Abstract : Four-month-old seedlings and 3-month-old cuttings of the polyembryonic mango cultivar Sabre were cultivated in washed quartz sand and supplied with 7 different nutrient solutions. Six of the solutions were prepared according to Homès' method of systematic variations; Hoagland's solution No.1 (half strength) served as a control. Contents of single nutrients in the leaf tissue were not correlated with rooting. However, rooting was significantly better in cuttings taken from seedlings than in those taken from vegetatively propagated stock plants. The main reason for this could be (i) the lower vigour, (ii) the higher nutrient content, or (iii) the higher root/shoot ratio of the seedlings.
