摘要

本研究在造林区内进行，使用来自Kastamonu的2+0年裸根苏格兰松幼苗。本研究旨在确定纳米颗粒(NP)的施用对幼苗形态特征和幼苗成活率的影响。采用三种不同浓度(低、中、高)和四种不同纳米颗粒类型[Fe₃O₄，CuO, ZnO, TiO2]对植物进行浸根处理。评价了NP处理对大田幼苗高(SH)、根颈直径(RCD)、茎鲜重(SFW)、根新重(RFW)、幼苗鲜重(SEFW)、根干重(RDW)、茎干重(SDW)、幼苗干重(SEDW)、结实商(SI)、根冠比(R/S)和幼苗成活率的影响。结果表明，NP类型对除RFW、SDW、RDW和SEDW外的所有幼苗变量均有显著影响，NP剂量对除RFW外的所有幼苗变量均有显著影响。NP类型和剂量的二元互作效应对所有幼苗变量均有显著影响，且均高于对照处理。中、高剂量NP比低剂量对幼苗生长更有效;对照处理的幼苗成活率为61.4%，tio2 -培养基NP组合处理的幼苗成活率为95%。

Effects of nanoparticle applications on seedling survival and morphological characteristics in Scots pine afforestation

This study was conducted in the afforestation area, using bare-root 2+0-year-old Scots pine seedlings from Kastamonu. The study aimed to determine the impact of nanoparticle (NP) applications on seedling morphological characteristics and seedling survival success. Three different concentrations (low, medium, high) and four different nanoparticle types [Fe₃O₄, CuO, ZnO, TiO2] were applied to the plant root-dipping method in the study. The effects of NP treatments on seedling height (SH), root collar diameter (RCD), stem fresh weight (SFW), root new weight (RFW), seedling fresh weight (SEFW), root dry weight (RDW), stem dry weight (SDW), seedling dry weight (SEDW), sturdiness quotient (SI), root: shoot ratio (R/S), and seedling survival in the field were evaluated. The study results revealed that NP types significantly affected all seedling variables except RFW, SDW, RDW, and SEDW, and NP doses significantly affected all seedling variables except RFW. The binary interaction effects of NP types and doses had a significant effect on all seedling variables, and higher values were obtained compared to the control treatment. Medium and high NP doses were more effective in seedling growth than low doses; the percentage of seedling survival was 61.4% in the control treatment and 95% in the TiO2-Medium NP treatment combination.
