The phrase "a specific leaf" is correct and usable in written English.
It can be used when referring to a particular leaf among many, often in contexts related to botany, gardening, or discussions about plants.
Example: "In our study, we focused on a specific leaf to analyze its photosynthesis rate."
Alternatives: "a particular leaf" or "one specific leaf".
As the main conclusion of this research, it can be said that counting particles instead of weighing particles on a specific leaf area seems to be a proper way to classify aerosol deposition on vegetation.
To incorporate the inter-class relationships, we generate the SVM-based discriminant function to contain the contributions from all nodes along the paths from a root to a specific leaf node by introducing the class attribute vectors [ 5].
However, using his results, and assuming a specific leaf area of 4 m per kg needle mass (from Hager and Sterba, 1985 for dominant trees), comparable results can be shown, namely a LA/CSA ratio of about 0.8 and only minor differences in this ratio between the two investigated stands, which differed clearly in age (98 and 132 years respectively), in site quality, and in density.
Coda's leaf isn't a representation of the idea of a leaf; it's a very specific leaf, the Coda leaf.
Reportedly, Si treated plants grown under saline stress have a larger leaf weight ratio and a smaller specific leaf area than untreated plants, which have smaller leaf surface areas and loss of water transpiration [ 58].
Although S. maritima has a high specific leaf area compared with H. portulacoides, the presence of a thicker cuticle is probably the factor responsible for this reduced diffusion underwater (Mommer et al. 2007).
The combination of shorter leaves and a lower specific leaf area indicated that plants developed under elevated CO2 had a smaller leaf area per unit biomass or the leaves became smaller and thicker.
The CSSL also had a lower specific leaf area (SLA) than Sasanishiki, reflecting its thicker leaves.
Plants grown under elevated carbon dioxide displayed a significantly faster growth rate of their lateral stems (stolons) and increased shoot and root dry weight but a reduced specific leaf area compared to those plants at ambient carbon dioxide levels.
The three cultivars with the greatest commercial root production also had the highest maximum values for A and the highest specific leaf area, indicating that these two parameters can be used to select for highly productive cultivars of A. xanthorriza.
The most noticeable effect is a reduction in specific leaf area (the ratio of leaf area to leaf dry mass) [ 25].
