the effects of 0, 1000, 4000, 8000 and 10000 ppm IBA and the combination of 150 ppm putrescine and 4000 and 8000 ppm IBA on the rooting and shoot of softwood cuttings have been studied.
The cuts of Pyrus elaeagrifolia Pall were made from both "Ahlat 1" (gray ahlat) and "Ahlat 2" (bright ahlat) species at three different times. and from the "Ankara" pear variety of Pyrus communis L. The best results for both species of Pyrus elaeagrifolia Pall. it was obtained in the first set of softwood cuttings. The rooting percentage, rooting level (0-4), root length, dry root weight, drying percentage, percentage of rooted and exiled steel were determined as 11.4%, 0.16, 1.79 cm, 0.009 g, 0.0% and 0.0% in these steels. The % was determined as 43.8% in "Ahlat 1" and 43.8%, 1.64, 6.52 cm, 0.199 g, 32.4% and 32.4% in "Ahlat 2", respectively. The differences in the averages of all IBA and IBA+ putrescine treatments for these parameters were not statistically significant. The highest root count (11.2) was obtained by applying 8000 ppm IBA from the first collected steel in "Ahlat 2". In the Ankara variety (Pyrus communis L.) the best results compared to the first softwood cutting were 36.2% rooting rate, 0.68 rooting, 2.8 root count and 0.145 g dry root weight.
