“…1 c,d). The results of our morphological characterization of Hahnii are similar to those of tropical dwarf accessions of Sansevieria with sizes that range from 8.59 to 12.08 cm 26 . A small size is a key advantage for a model plant species 27 , 28 .…”

Sansevieria trifasciata is used as an indoor plant, in traditional medicine and as a fiber source. Here we characterized fibers of two of varieties of S. trifasciata, Lorentii and Hahnii, and report a protocol for their propagation based on indirect shoot organogenesis. Structural and ribbon fibers were scattered within leaf parenchyma when viewed with confocal laser scanning microscopy. Chemical analysis of the fibers by mass spectrometry and high-performance chromatography revealed higher contents of cellulose and xylose in Lorentii than in Hahnii and significant differences for total lignin between both. A protocol for de novo shoot production was then developed using leaf explants. Time-course histological analyses showed that the first events of transdifferentiation were triggered preferentially in cells surrounding fibers and vascular bundles. Callogenesis and shoot performances were quantified for both varieties, and 2,4-D at 2 and 3 mg·L-1 yielded the best results for primary calli induction and fresh calli mass. The length, number, and mass of shoots produced did not differ significantly between the two cultivars. The fast morphogenic response of S. trifasciata to in vitro culture may be useful for mass propagation or other biotechnological purposes such as metabolite production.

“…In this study, the investigation of this relationship, using the measure of dimensions D and E, as illustrated in Figure 3, confirms the relevance of these characteristics. The studies that were performed by Paula et al (2021), Rêgo et al (2020) and Salvaña et al (2019) also proved the possibility of using morphological characteristics of leaves as a method to characterize plant varieties. These results emphasize the relevance of these characteristics in scientific research, especially in studies that address the genetic diversity of plants.…”

Catharanthus roseus is a prominent medicinal plant containing quantities expressive of alkaloids vincristine and vinblastine in its tissues. For this reason its use has been used in the treatment of cancer patients. Also it plays a significant role with use in floriculture, due to its variety of flower colors, because they are used more and more in landscaping projects. To potentiate its use, know its genetic diversity becomes important to optimization of the improvement of species. Thus, this work aimed to analyze the effect of 17 quantitative morphological variables to the distinction genotypes of C. roseus and to evaluate the genetic variability. Therefore, an experiment was carried out, evaluating ten commercial varieties of C. roseus, in greenhouse, in a randomized block design, with three replications. After 100 days of planting, the morphological profiles of the varieties were analyzed using image phenotyping. Through the analysis of genetic dissimilarity, the varieties were categorized into three groups, and the leaf traits were the ones that most contributed to this categorization. Therefore, the morphological characterization was efficient to characterize the phenotypic variability of the evaluated genotypes.

Leaf characterization of rubber clones needs to be done from the start, especially for plants in the budwood garden. This function is to produce genetically pure and original plants. The purpose of this study was to characterize the IRR series 400, RRIC 100, and BPM 24 clones based on leaf character using the leafgram method. The types of clones that were characterized were IRR 425, IRR 428, IRR 429, IRR 434, IRR 440, RRIC 100, and BPM 24. The leaves characterized were the middle leaves of each clone as many as 50 leaves per clone, divided into three replications. The leaf characters observed were length, width, top fold point, center point, left strand, large, apex angle, vein angle, basal angle, apex kite angle, basal kite angle, ratio length/width, ratio length/top fold point, ratio left strand/large/ ratio left strand top fold point, ratio left strand/center point, ratio top fold point/large, ratio top fold point/center point, ratio apex/basal angle, ratio vein/apex angle, ratio vein/basal angle and ratio apex kite/basal kite angle. Data were analyzed using MINITAB 16 software and Microsoft Office 2010. The characterization results showed that the distinguishing characters that can be used as characteristic of characters are width, left strand, apex angle, basal angle, ratio length /width, ratio left strand/top fold point, ratio left strand ratio/center point, ratio top fold point/large, ratio apex/basal angle, ratio vein/apex angle, and ratio vein/ basal angle.
