Abstract

Cyclocarya paliurus (Batalin) Iljinsk is an endangered subtropical tree species in China with high pharmacological and economic value, yet its large-scale cultivation remains limited. Understanding provenance-level variation in C. paliurus is essential for identifying elite germplasm suitable for leaf-oriented, tea-style plantation systems. In this study, seedlings of six natural provenances, including Xiushui (XS), Shimen (SM), Lushan (LS), Jianghua (JH), Hupingshan (HP), and Shuangpai (SP), were grown under tea plantation-style cultivation conditions to evaluate differences in growth performance, leaf morphology, anatomical structure, physiological traits, stress resistance, and productivity and to identify superior germplasm for industrial development. Phenotypic differentiation was observed despite the uniform environment, indicating strong genetic control and long-term climatic adaptation. Provenances originating from moderate, mid-elevation climates (SM, SP) exhibited superior early growth and the highest productivity indices. In contrast, provenances from colder or thermally variable habitats (LS, XS, HP) displayed smaller or more compact leaves, increased tissue density, enhanced protective structures, and higher cold or drought resistance. Anatomical traits, including mesophyll thickness, stomatal density, and glandular trichome abundance, further reflected adaptive trade-offs between carbon assimilation and stress protection. Overall, the clear divergence in leaf form, structure, biomass allocation, and stress-related traits among provenances underscores the strong influence of native climatic conditions. These findings provide important guidance for matching provenance characteristics to plantation environments and support the targeted selection of high-yield, stress-tolerant germplasm for industrial-scale, tea plantation-style cultivation of C. paliurus.

Özet

Cyclocarya paliurus (Batalin) Iljinsk, Çin'de yüksek farmakolojik ve ekonomik değere sahip, nesli tükenmekte olan bir subtropikal ağaç türüdür, ancak büyük ölçekli yetiştiriciliği hala sınırlıdır. C. paliurus'un menşe düzeyindeki varyasyonlarını ortaya çıkarmak, yaprak odaklı, çay tarzı plantasyon sistemlerine uygun seçkin genotiplerini belirlemek için çok önemlidir. Bu çalışmada, Xiushui (XS), Shimen (SM), Lushan (LS), Jianghua (JH), Hupingshan (HP) ve Shuangpai (SP) olmak üzere altı farklı doğal menşeye ait fideler endüstriyel üretime uygun olabilecek genotipleri belirlemek amacıyla, benzer çay plantasyonu tarzı yetiştirme koşulları altında yetiştirilmiştir. Bir yıllık fideler büyüme performansı, yaprak morfolojisi, anatomik yapı, fizyolojik özellikler, stres direnci ve verimlilik açısından analiz edilmiştir. Tekdüze büyüme ortamına rağmen menşeler arasında gözlemlenen fenotipik farklılıklar güçlü genetik kontrol ve uzun vadeli iklim adaptasyonunu göstermektedir. Ilıman, orta rakımlı iklimlerden (SM, SP) gelen kökenler, üstün erken büyüme ve en yüksek verimlilik indeksleri sergilemiştir. Buna karşılık, daha soğuk veya termal olarak değişken habitatlardan (LS, XS, HP) gelen kökenler, daha küçük veya daha kompakt yapraklar, artmış doku yoğunluğu, gelişmiş koruyucu yapılar ve daha yüksek soğuk veya kuraklık direnci sergilemiştir. Mezofil kalınlığı, stoma yoğunluğu ve salgı tüylerinin bolluğu gibi anatomik özellikler, karbon asimilasyonu ve stres koruması arasındaki adaptif dengeleri güçlü bir şekilde ortaya koymuştur. Genel olarak, kökenler arasında yaprak şekli, yapısı, biyokütle dağılımı ve stresle ilgili özelliklerdeki belirgin farklılıklar, yerel iklim koşullarının güçlü bir etken olduğunu göstermiştir. Bu bulgular, köken özelliklerinin plantasyon ortamlarına adaptasyonu ve C. paliurus'un endüstriyel ölçekte çay plantasyonu tarzı yetiştiriciliği için yüksek verimli, strese dayanıklı genotiplerin seçiminde bilimsel bir temel sunmaktadır.
