Abstract:
Abstract Background and Aims Leaf size has considerable ecological relevance, making it desirable to obtain leaf size estimations for as many species worldwide as possible. Current global databases, such as TRY, contain leaf size data for ~30 000 species, which is only ~8% of known species worldwide. Yet, taxonomic descriptions exist for the large majority of the remainder. Here we propose a simple method to exploit information on leaf length, width and shape from species descriptions to robustly estimate leaf areas, thus closing this considerable knowledge gap for this important plant functio

Abstract:
This study aimed at determining the leaf area in Liquidambar styraciflua L. and at characterising the relationship between leaf area and leaf descriptors. The biological material was the species Liquidambar styraciflua L. We determined leaf area in 100 leaves (Figure 1) based on the size of median rib (L), leaf width at higher (W1) and lower (W2) lobe level, and on area constants (KA). The size of elements L, W1 and W2 were found by measuring with a precision of ±0.5 mm. Area constants in the species Liquidambar styraciflua L. were KA1 = 0.63, determined depending on leaf width at upper lobe w

Rice is very important for Pakistan’s economy. To increase rice exports and ensure food security, it is essential to plan development patterns and select the best rice genotypes for cultivation. This research was done at the Agricultural Research Institute in Dera Ismail Khan, Pakistan during the Kharif season, 2020. The study characterized five rice varieties by inspecting various seedling’s attributes and growth stages. A randomized complete block design with three replications was used to minimize bias in the study. Data collected at 10, 20, 30, and 40 days after transplantation

Abstract:
The leaf area, as an important leaf functional trait, is thought to be related to leaf length and width. Our recent study showed that the Montgomery equation, which assumes that leaf area is proportional to the product of leaf length and width, applied to different leaf shapes, and the coefficient of proportionality (namely the Montgomery parameter) range from 1/2 to π/4. However, no relevant geometrical evidence has previously been provided to support the above findings.

Abstract:
Original objectives: To understand the regulation of abscission by exploring the nature of changes of auxin-related gene expression in tomato (Lycopersicon esculatumMill) abscission zones (AZs) following organ removal, and by analyzing the function of these genes. Our specific goals were: 1) To complete the microarray analyses in tomato flower and leaf AZs, for identifying genes whose expression changes early in response to auxin depletion; 2) To examine, using virus-induced gene silencing (VIGS), the effect of silencing target genes on ethylene sensitivity and abscission competence of the lea

Abstract:
Original objectives: Understanding the regulation of abscission competence by exploring the nature and function of auxin-related gene expression changes in the leaf and pedicelAZs of tomato (as a model system), was the main goal of the previously submitted proposal. We proposed to achieve this goal by using microarray GeneChip analysis, to identify potential target genes for functional analysis by virus-induced gene silencing (VIGS). To increase the potential of accomplishing the objectives of the previously submitted proposal, we were asked by BARD to show feasibility for the use of these two
