Abstract

The present investigation was carried out at Agricultural Scientific Research Center in Latakia, during (2011-2013) to study the propagation of male kiwi trees by wooden cuttings. Two dates for collecting cuttings (January and February) from kiwi trees were selected. On every date, the cuttings were divided into three groups according to cutting location on the shoot (basal, middle and apical). The NAA and IBA regulators were applied at two concentrations (5000, 6000 ppm).  In addition, there were four treatments of the mixture of both growth regulators. The cuttings were planted within the glasshouse for 60 days under sprinkle irrigation conditions. Then, the effect of cutting collection date, cutting location on shoot and the concentration of growth regulators on; number of rooted cuttings, total number of roots, average root weight and volume, and average shoot weight and volume. The results showed that the first date (end of January) is more significant than end of February according to weight and volume of both root and shoot, also in number of rooted cuttings, where the rooting ratio was 64.9%, 54.3% respectively. According to cutting location on the shoot, the middle and basal cuttings were significantly increased in term of root weight (20.31 g, 19.81g), while the apical cutting was 15.55 g.  According root volume, the result was 20.55cm3– 20.06 cm3 and 15.57 cm3 for apical cuttings. The NAA and IBA growth regulators showed different effect; where NAA was significantly superior to IBA, and the mixture treatments in terms of the average number of roots/cuttings. While IBA and the mixture treatments were significantly superior over NAA in terms of shoot weight and volume. The treatment with the mixture (IBA3000 + NAA3000 ppm) was significantly superior to the other treatments in terms of the average weight and volume of the roots. The treatment with the mixture (IBA1500 + NAA1500 ppm) was significantly superior to the other treatments in terms of the number of rooted cuttings by rooting (75%) compering to the control (28%).

Abstract

The present investigation was carried out at Latakia Agricultural Research Center, during (2011-2013), to study the propagation of male kiwi trees by wooden cuttings at two collecting dates (January and February). NAA and IBA regulators were applied at two concentrations (5000, 6000 ppm). In addition, of four treatments of the mixture of both regulators. The cuttings were planted within a glasshouse for 60 days under sprinkle irrigation conditions in order to study the effect of some factors (collecting date, location of cuttings on shoot, type of regulator and its concentrations) on some characters of cuttings (rooting ratio%, weight and size of roots, and weight and size of shoots. The results showed that the first collecting date (January) was significantly better in terms of weight and number of roots and shoots and rooted cuttings number. The rooting ratio was 64.9%, 54.3% respectively. According to cutting location on the shoot, the middle and basal cuttings were exceeded significantly the typical one in term of roots weight (20.31, 19.81, 15.55 g respectively) and also according to root size (20.55, 20.06, 15.57 cm3 respectively). The NAA and IBA regulators; had different effects, where the regulator (NAA) was significantly superior to the regulator (IBA) and the mixture treatments in terms of the average number of roots / cuttings. While the shoot weight and size were higher at IBA and mixture treatments than NAA. The mixture treatment 3000 ppm of (IBA + NAA) gave high values of roots weight and size. The treatment of 1500 ppm of mixture (IBA+ NAA) was significantly superior compared to the other treatments in terms of the number of rooted cuttings (75%) comparing to the control (28%).
