| description |
Background and aims: Ligustrum sinense (Chinese privet) is a recognized invasive exotic species. The objective of this study was to determine the physiological and foliar anatomical traits of Chinese privet saplings that would give it an advantage for its establishment in the understory of the Yungas forest environment.
M&M: This study was conducted in Parque Nacional Aconquija (Tucumán, Argentina). The foliar physiological and morpho-anatomical traits deployed were investigated in an understory environment during spring-summer and winter. The anatomical features of the leaf blade and physiological variables related to gas exchange were analyzed. Also, the specific leaf area, leaf density, leaf nitrogen content and photosynthetic efficiency in the use of leaf nitrogen were calculated.
Results: During spring-summer L. sinense displays a higher photosynthetic assimilation rate and a better photosynthetic nitrogen-use efficiency. Carboxylation efficiency, intrinsic water use efficiency, and leaf thickness were 26%, 34%, and 41% higher, respectively, during winter in contrast to spring-summer. During winter an increase in leaf thickness contributed to improved CO2 incorporation during suboptimal conditions for photosynthesis.
Conclusions: Chinese privet undergoes photosynthesis throughout the year and its success as an invasive species in the Yungas forest understory could be attributed at least in part to morpho-anatomical and physiological strategies. |

Introducción y objetivos: Ligustrum sinense (ligustrina) es una reconocida especie exótica invasora. El objetivo de este trabajo fue estudiar los rasgos fisiológicos y anatómicos foliares de renovales de ligustrina que podrían otorgarle ventajas para su establecimiento en un ambiente de sotobosque de la selva de Yungas. M&M: Este estudio se realizó en el Parque Nacional Aconquija (Tucumán, Argentina). Se evaluaron los rasgos morfo-anatómicas foliares y fisiológicos en un ambiente de sotobosque durante primavera-verano e invierno. Se analizaron las características anatómicas de la lámina foliar y variables fisiológicas relacionadas al intercambio de gases. Además, se calculó el área foliar específica, densidad de hojas, contenido de nitrógeno foliar y eficiencia fotosintética en el uso del nitrógeno foliar. Resultados: Durante primavera-verano L. sinense muestra una mayor eficiencia fotosintética en el uso del nitrógeno foliar y una mayor asimilación fotosintética en condiciones saturantes. La eficiencia de carboxilación, eficiencia intrínseca del uso del agua y espesor de hoja fueron 26%, 34% y 41% mayores en invierno con relación a primavera-verano. Durante el invierno se registró un aumento en el espesor de la lámina lo que contribuiría a mejorar el intercambio de CO2 en época de condiciones subóptimas para la fotosíntesis. Conclusiones: La ligustrina fotosintetiza todo el año y su éxito para establecerse en el sotobosque de la selva de Yungas podría explicarse en parte por las estrategias morfo-anatómicas y fisiológicas desplegadas.
