ABSTRACT

The aim of the research carried out at greenhouse located at UASVM Bucharest was to evaluate the efficiency of hardwood cutting for Actinidia deliciosa cv. Hayward (green kiwi fruit) grown on three different substrates formulated from sand (S), perlite (P) and mixture of sand with perlite (S+P) (1:1, volumetric ratio) after various hormonal rooting treatments, as it follows: Radistim, naphtylacetic acid (NAA) 2000 ppm, beta-indolyl butyric acid (IBA) 2000 ppm and NAA + IBA 1000 ppm. The evaluation of the efficiency of hardwood cutting after application of hormonal rooting solutions was assessed by rooting percentage, number of formed roots, roots lengths (cm/cutting). Results indicated that the highest rooting percent (73.1%) and the highest number of formed roots (17.2) were found when were used NAA+IBA 1000 ppm solution and S+P substrate. The highest value of root length (19.7 cm/cutting) was recorded in the case of Radistim application using S+P substrate.
