Abstract:

In the study conducted in Samsun-Gelemen Forest Fidan, the objective is to determine the morphological quality characteristics of Samsun-original tubular fidanes (Pinus pinea L.) of different ages. For this purpose in determining the morphological characteristics of the plants; the root throat diameter (CCC), the plants length (FB), the terminal extraction length (TSB), the root fresh weight (KTA), the body fresh weight (GTA), the root dry weight (KKA), the body dry weight (GKA), the plants dry weight (FKA), the curvature index (GI), the dry root percentage (%KKK), the rigidity index (KI) and the Dickson quality index (DI) are based on the criteria. According to the detected morphological characteristics, the beans were evaluated according to the Turkish Standards Institute (TSE) criteria and the Aphalo and Rikala (2003) GI value. The morphological quality characteristics of the 2+0 and 3+0 old polyethylene pipe beans cultivated according to the average; KBC: 7.92-11.8 mm; FB: 39,06-65,3 cm; TSB: 15,93-31,77 cm; KTA: 6,59-14,26 gr; GTA: 31,99-85,42 gr; KKA: 2,54-6,18 gr; GKA: 12,09-33,84 gr; FKA:14,63-40,02 gr; GI: 49,01-56,44; %KKK: 17-16; KI: 4,99-5,61; DKI:1,5-3,65 is determined. In terms of the IQ criterion, 76.7 percent of 2+0 elderly beans, and 90 percent of 3+0 elderly beans are "Iskarta". It is believed that the plants of the existing morphological standard can only be used in landscape trees.

Abstract:

It was aimed to determine the morphological quality characteristics of containrised stone pine (Pinus pinea L.) seedlings originated from Samsun at different ages in this study performed in Samsun-Gelemen Forest Nursery. For this purpose, Root collar diameter (RCD), seedling height (SH), the lenght of terminal shoot (LTS), root fresh weight (RFW), stem fresh weight (SFW), root dry weight (RDW), stem dry weight (SDW), seedling dry weight (SEDW), sturdiness index (SI), dry root percentage (DR%) shoot-root ratio (SRR) and Dickson Quality Index (DQI) criteria were choosed for detectioning morphological characteristics of the seedlings. According to the morphological characteristics identified, seedlings were evaluated in terms of Turkish Standart Institute (TSI) criterias and the SI values of Aphalo and Rikala (2003). Morphological quality characteristics of grown 2+0 and 3+0 aged polyethylene containerised seedlings were determined as RCD: 7,92-11,8 mm; SH: 39,06-65,3 cm; LTS: 15,93-31,77 cm; RFW: 6,59-14,26 gr; SFW: 31,99-85,42 gr; RDW: 2,54-6,18 gr; SDW: 12,09-33,84 gr; SEDW:14,63-40,02 gr; GI: 49,01-56,44; DR%: 17-16; SRR:4,99-5,61; DQI: 1,5-3,65 respectively. 76.7% of 2+0 aged, and 90% of 3+0 aged seedlings in terms of KI criteria is “unsuitable”. It is thought that seedlings of the current morphological standard can only be used in afforestation for landscaping purposes.
