PCPM (Prunus cerasifera X Prunus microcarpa ) hybrid rootstock candidate: Identification and production possibilities with hardwood cutting
Abstract
This study was conducted in the laboratories and greenhouses of Eastern Mediterranean Transitional Zone Agricultural Research Institute between 2018 and 2020 to identify botanical characteristic of PCPM (Prunus cerasifera X Prunus microcarpa), which is natural hybrid of Prunus cerasifera (PC) and Prunus microcarpa (PM), and to investigate slip production opportunities of it at different IBA 1000 mg L-1, 2000 mg L-1, 3000 mg L-1, 4000 mg L-1. PCPM which was noticed in its natural environment, was followed in botanical terms for 3 years. It was determined that the average fruit weight, fruit width, and fruit length values of PCPM were 1.33 g, 11.93 mm and 12.50 mm, respectively.The soluble solid contents (SSC) values were measured as 15.03 brix in PC, 25 brix in PM, and 27.66 brix in PCPM. It was determined that the annual shoot development was 124.98, 8.41, and 26.15 cm, and the leaf lengths were 64.99, 21.18, and 41.93 mm in PM, PC, and PCPM, respectively. It was also determined that PCPM showed a botanic characteristic between PM and PC, which are its parents in general botanical terms. In rooting with hardwood cutting for PCPM, it showed similar values with Myrobolan 29C, which was the control rootstock, and had average rooting percentage as %80.11, and the average number of roots as 5.27 pcs/slip. The results had a positive effect on rooting increase in hormone application of 2000 mgL-1 concentration with IBA compared with other applications.
