Abstract

This study aimed to provide insights on intraspecific variability of photosynthesis performance of 19 provenances of black pine planted in a common garden. The experiment was conducted in an experimental trial located at Souiniet (the southern limit of its range) Photosynthetic capacity characterized by light-saturated net photosynthetic rates, associated light compensation points and apparent quantum yield was monitored by measuring the response of leaf gas exchange to light levels. Amax was the highest in provenances Puget Theniers (nigra ssp), Saint-Guilhem (salzmanni ssp), Marghese and les barres (laricio ssp). The lowest value was recorded in Olette of the subspecies salzmanni. Needles from two provenances Crimea (pallasiana ssp) and Les Barres (ssp laricio) revealed the highest apparent quantum yield (ɸ), followed by Brougatlès Ales (salzmanni ssp), Trenta Coste (ssp laricio), Les barres and Puget Theniers (nigra ssp). The lowest apparent quantum Yield was recorded in Laricio subspecies (Cosenza; Les barres and Bois frerot). The highest value of dark respiration (Rd) was shown in provenance Les barres (laricio ssp), while Grancia and Tavola of the laricio subspecies reported the lowest one. Provenances Tavola (laricio ssp) and Puget Theniers (nigra ssp) exhibited the highest LCP. The provenance Crimée (pallasiana ssp) and Aspromonto (laricio ssp) recorded the lowest values. The maximum values of photosynthesis are positively correlated with the total chlorophyll contents and Leaf Mass area. Our study illustrates that Photosynthesis performance showed a difference between 19 provenances of black pine; it seems that black pine photosynthetic performance is eco-typical independent.

A/PFFD对黑松光合性能的生态型影响

本研究的目的是了解普通园林19个种源黑松光合性能的种内变异。通过测量叶片气体交换对光照水平的响应，监测以光饱和净光合速率、相关光补偿点和表观量子产率为表征的光合能力。Amax在普吉特特尼尔斯(nigra ssp)、圣吉尔海姆(salzmanni ssp)、马格塞(Marghese)和莱斯巴雷斯(laricio ssp)种源中最高。最小值记录在salzmanni亚种的Olette。两个种源克里米亚(pallasiana ssp)和Les Barres (ssp laricio)的表观量子产率最高，其次是brougatl Ales (salzmanni ssp)、Trenta Coste (ssp laricio)、Les Barres和Puget Theniers (nigra ssp)。Laricio亚种(Cosenza;Les barres和Bois frerot)。暗呼吸(Rd)值以种源Les barres (laricio ssp)最高，落叶松亚种Grancia和Tavola最低。种源Tavola (laricio ssp)和Puget Theniers (nigra ssp)的LCP最高。种源crimone (pallasiana ssp)和Aspromonto (laricio ssp)的值最低。光合作用最大值与总叶绿素含量和叶质量面积呈正相关。研究表明，19个种源间黑松光合性能存在差异;似乎黑松的光合性能是生态典型独立的。

期刊介绍： Notulae Botanicae Horti Agrobotanici Cluj-Napoca is a peer-reviewed biannual journal aimed at disseminating significant research and original papers, critical reviews and short reviews. The subjects refer on plant biodiversity, genetics and plant breeding, development of new methodologies that can be of interest to a wide audience of plant scientists in all areas of plant biology, agriculture, horticulture and forestry. The journal encourages authors to frame their research questions and discuss their results in terms of the major questions of plant sciences, thereby maximizing the impact and value of their research, and thus in favor of spreading their studies outcome. The papers must be of potential interest to a significant number of scientists and, if specific to a local situation, must be relevant to a wide body of knowledge in life sciences. Articles should make a significant contribution to the advancement of knowledge or toward a better understanding of existing biological and agricultural concepts. An international Editorial Board advises the journal. The total content of the journal may be used for educational, non-profit purposes without regard to copyright. The distribution of the material is encouraged with the condition that the authors and the source (Notulae Botanicae Horti Agrobotanici Cluj-Napoca or JCR abbrev. title Not Bot Horti Agrobo) are mentioned.
