“…Puji asmanto et al (2007) menyatakan bahwa Andrographis paniculate pada ketinggian sedang (400-700 mdpl) menghasilkan tanaman yang lebih tinggi disbanding dataran rendah (<400 mdpl) dan tinggi (>700 mdpl). Secara anatomi, daun Epilobium amurense, Pedicularis densispica, dan Potentilla fulgens menunjukkan peningkatan ketebalan jaringan epidermis atas dan bawah seiring dengan peningkatan ketinggian tempat tumbuh (Liu et al, 2020). Sedangkan Crocus sativus pada ketinggian sedang (700 m) dan tinggi (1400 m)memiliki kutikula yang lebih tebal dengan kerapatan stomata menurun dibandingkan ketinggianrendah (<700 m) (Zarinkamar et al, 2011).…”

Vernonia cinerea L. (sawilangit) is a wild plant that has potential as a medicinal plant because of the secondary metabolites in each organ. This research aimed to explore the morphological and anatomical characters of the sawilangit that grow at different altitudes in Banyumas, Cilacap, and Purbalingga. Plant samples were taken using the purposive random sampling method at an altitude of <350 masl, 350–700 masl, and >700 masl. Sawilangit growing at <350 masl has superior morphological and anatomical characters than sawilangit growing at the other two altitudes, which have the characteristics of taller, wider leaf, larger stem diameters, and darker flower color. The observation on quantitative of morphological and anatomical characters showed that sawilangit at <350 masl has an average height of 66.17 cm, root diameter of 0.33 cm, stem diameter 0.32 cm, leaf length and width of 5.7 cm and 2.14 cm, and stomata index of 0.28. These results indicated that altitude <350 masl is suitable for sawilangit growth because it can produce optimal morphological and anatomical characteristics.

“…Leaves are sensitive to ecological factors and have strong plasticity. Under different environmental pressures, the anatomical characteristics of leaves have evolved special characteristics that are compatible with heterogeneous habitats [10]. Drought stress has been shown to thicken the stratum corneum and palisade tissue of Populus euphratica [11], but decrease leaf thickness in Eucalyptus robusta [12].…”

The ability of plants to adapt to environmental variability and self-regulate in complex habitats often reflected in leaf anatomical changes. In an assessment of 19 characteristics of Betula albosinensis leaves, samples were taken from trees grown along an altitudinal gradient on the eastern edge of the Qinghai-Tibet Plateau and distributed at three altitudes: 2434 m, 2824 m, and 3060 m. Anatomical characteristics of the leaves' blade, mesophyll, and midrib were studied using paraffin slice technology. We found that altitudes and changes in altitude affected the leaf anatomy. As altitude increased, the blade and the mesophyll became thinner, and the transport tissues of the midrib became relatively underdeveloped. However, intra-altitudinal variation was the main source of phenotypic variance. Pearson correlation and principal component analysis revealed that each trait had different ecological dimensions, and that there were trade-offs and covariance relationships between traits. In summary, to adapt to the local altitudinal conditions, Betula albosinensis may exhibit multiple responses, such as reducing investment in leaves, which can boost short-term growth rates, and the "quick investment and return" strategy. Our findings are useful in understanding anatomical adaptations and their trade-offs to environmental variation.

“…Changes in functional traits have significant impacts on the structure and composition of forests and the overall functioning of the ecosystem 13 . For example, functional trait changes provide support for trait-based habitat filtering in plant community 14 , species coexistence, and adaptive plant strategy 15 – 17 . However, the causes of high variability in leaf morphological and eco-physiological traits are due to different edaphic and climatic conditions, which assist in the coexistence and adaptation of the species in a forest ecosystem 18 .…”

Leaf functional traits support plant survival and growth in different stress and disturbed conditions and respond according to leaf habit. The present study examined 13 leaf traits (3 morphological, 3 chemical, 5 physiological, and 2 stoichiometry) of nine dominant forest tree species (3 coniferous, 3 deciduous broad-leaved, 3 evergreen broad-leafed) to understand the varied response of leaf habits. The hypothesis was to test if functional traits of the conifers, deciduous and evergreen differ significantly in the temperate forest and to determine the applicability of leaf economic theory i.e., conservative vs. acquisitive resource investment, in the temperate Himalayan region. The attributes of the functional traits i.e., leaf area (LA), specific leaf area (SLA), leaf dry matter content (LDMC), leaf water content (LWC), stomatal conductance (Gs), and transpiration (E) followed the order deciduous > evergreen > coniferous. Leaf carbon and leaf C/N ratio showed the opposite pattern, coniferous > evergreen > deciduous. Chlorophyll (Chl) and photosynthetic rate (A) were highest for evergreen species, followed by deciduous and coniferous species. Also, structural equation modelling determined that morphological factors were negatively related to physiological and positively with chemical factors. Nevertheless, physiological and chemical factors were positively related to each other. The physiological traits were mainly regulated by stomatal conductance (Gs) however the morphological traits were determined by LDMC. Stoichiometry traits, such as leaf C/N, were found to be positively related to leaf carbon, and leaf N/P was found to be positively related to leaf nitrogen. The result of the leaf functional traits relationship would lead to precise prediction for the functionality of the temperate forest ecosystem at the regional scale.
