“…Leaf area is among the factors that condition plant performance in natural and agricultural ecosystems, which is related to photosynthetic capacity (relative leaf growth rate, net assimilation rate, and photosynthetic efficiency), biomass production, competition, nutrition, soil-plant relationship, and, as a result, leaf area is used as a parameter in plant physiology and production (Macário et al 2020, Adji et al 2021, Boyaci and Küçükönder 2022.…”

Umbu (Spondias tuberosa Arruda, Anacardiaceae) is a fruit species native to the semi-arid region of Brazil and economically important for several regions. The objective of this study was to determine equations to estimate the leaflet area of S. tuberosa genotypes.A total of 1,000 leaflets was collected from four genotypes (250 leaflets of each genotype) of S. tuberosa. In each leaflet collected, the length, width, and leaflet area were measured, and the product between length and width was calculated. Linear, linear with intercept, power, and exponential regression models were used to fit the equations. The criteria for choosing the best equation were based on Pearson's correlation coefficients, Akaike's information criteria, Willmott's concordance indices, and root mean square error. The product-adjusted equations between length and width can be used to estimate the leaflet area of all S. tuberosa genotypes. The leaflet area of the species (pooled data) can be estimated accurately and quickly from equations obtained with the linear models without intercept (ŷ = 0.6911*LW) and power (ŷ = 0.7127*LW 0.9888 ).

“…The leaf area of an individual tree is therefore closely related to photosynthesis and productivity [19]. Specific leaf area (SLA), defined as the ratio of leaf area to leaf dry biomass, is a useful measure which provides a good indicator of the potential photosynthetic rate and plant productivity [20,21]. Many studies have reported that the regularity of SLA increases from the tree tip downward to the crown base and that the amount and distribution of foliage biomass of the whole tree ultimately affects the canopy position of trees [12,22].…”

“…Competitive interactions between individual trees lead to the mortality of branches in the lower part of the crown [27]. For this reason, allometries of foliage biomass are generally used for predictive models that consider tree size and/or leaf characteristics as independent variables [20,28]. Neighbor competition typically produces a large effect on crown asymmetry and thus affects the amount of foliage and its distribution [29].…”

The characteristics and distribution of foliage biomass are important aspects of the crown structures of trees. In this study, we developed a foliage biomass distribution model at the branch level and annual shoot level (i.e., all branches on an annual increment of the main tree bole) using a sample of 51 Korean pine trees that were destructively sampled in Liaoning Province, northeast China. A variety of independent variables, including branches, trees, and forest competition, were used as explanatory variables in the model development. Our results indicated that foliage biomass at the branch level increased with an increasing relative distance from the tree tip into the crown. The peak of the foliage biomass distribution shifted to the tree tip with increasing tree age. A power function, including branch diameter and competition variables, showed excellent performance in modeling branch foliage at the branch level. The final model, which included branch diameter, competition variables, and relative distance to branch base for the relative foliage density, showed best performance. The trees that showed advantageous growth ability also had a larger amount of foliage biomass.

“…Even though these two native tree species are often found in field crops or open dry forests in the central and northern parts of the country [6], they are still overexploited for their multiple uses and exposed to a loss of diversity that may eventually lead to their extinction [7,8]. This high pressure is a real threat to their diversity and survival [9].…”

Seed size is a critical factor that can impact the regeneration process of plant populations. The objective of this study is to identify optimal seeds for the cultivation of two overexploited native forest species in Côte d’Ivoire, namely Khaya senegalensis (Desr.) A.Juss., 1830 and Parkia biglobosa (Jacq.) R.BR. ex G. Don, 1830. A total of 1080 seeds per species were evaluated for germination and seedling vigour in two distinct environments (dry and humid) in Côte d’Ivoire. The results demonstrated that, for Khaya senegalensis, larger seeds exhibited higher germination rates, whereas for Parkia biglobosa, smaller and medium-sized seeds showed better germination performance. However, regardless of species and study site, larger seeds consistently produced more vigorous seedlings. In this case, pretreatment tests on large seeds of Parkia biglobosa can potentially enhance their germination performance. Large seeds, ranging from 0.25–0.37 g in Khaya senegalensis and 0.2–0.32 g in Parkia biglobosa, appear to be the most suitable and best candidates for high-quality, high-performance seeds to optimise the cultivation of these species in Côte d’Ivoire. Distributing such seeds to farmers can contribute to the success of reforestation and agroforestry programs involving these target species in Côte d’Ivoire. These findings contribute to the sustainable management of the target species and can serve as a basis for restructuring forest regeneration policies in Côte d’Ivoire.
