説明

Propagation of Ajuga reptans L.‹Atropurpurea› by leaf cutting was studied with the aim of increasing the efficiency of the nursery plant production. The conditions for root formation were revealed using an incubator. The optimum temperature for root fomation was 20-25°C. Above 2500 lx of light intensity were needed to achieve the sufficient amount of root formation. The leaf cuttings were stored up to four weeks in darkness at 0-5°C. The roots developed not only from a whole leaf but also from the edge of the top half as well as the lower half of the leaf. When the cuttings were planted in pots with fertilizer and placed outside, they grew to 14 cm in diameter. The growth of the leaf cuttings was investigated by planting them in a pot with fertilizer under field conditions. The optimum season for planting of cuttings was June or July. When the cuttings were potted during this season, they grew to about 10 cm in diameter and could then be transplanted in a field. When two leaf cuttings were potted, the percentages of rotted cuttings was decreased and the growth increased by about two times that of one leaf cutting.
