“…The data can be used in the species identification, a parameter which was also used by Silva et al (2014). The type of fruit is a diagnostic feature of the Leguminosae, according to Barroso et al (1999), Lopes et al (2012), Ojeda et al (2013), Albuquerque et al (2015), and the classic studies in morphology. Barroso et al (1999) classified the genus Apuleia as samaroid-type legume, dry undeiscent, flat and compressed, adapted to anemochorous seed dispersal with one to a few seeds, oblique, slightly coriaceous, with sparing-spongy mesocarp.…”

-Apuleia molaris spruce ex benth, commonly known in Brazil as "amarelão," is a fast-growing forest plant with a potential for use in reforestation; however, there is little information about the physiology and morphology of its fruits, seeds, and seedlings. Thus, the objective of this work was to describe the morphology of the fruits, seeds, and seedlings, in addition to the anatomic patterns of seedlings, as a contribution to the technical-scientific knowledge and production of amazonian species for reforestation in the state of Pará. For this purpose, the morphological descriptions followed the parameters from specialized literature and the common techniques used in plant anatomy. The species presents leguminous fruit; seeds with pleurogram, average dimensions of 51.21, 21.33, and 2.09 mm length, width, and thickness, respectively; and seedlings with eophyll and pinnate metaphylls, cordiform, phanerocotylar germination, epigaeous, and foliaceous. Eophylls and metaphylls present uniseriate epidermis, collateral and dorsiventral vascular bundle. The morphological characteristics may help in field identification and in the identification of young plants, aiding the production of seedlings of this species. Furthermore, anatomically, the hypocotyl has no striking differences from the root.Index terms: taxonomic identification, seedling production, seed technology.Aspectos morfológicos de frutos, sementes e morfo-anatômico de plântulas de apuleia molaris spruce ex benth.RESUMO -O amarelão (Apuleia molaris Spruce ex Benth.) é uma essência florestal de rápido crescimento, com potencial para o reflorestamento, entretanto existem poucas informações a respeito da tecnologia e morfologia dos frutos, sementes e plântulas. Com isso, o objetivo do presente trabalho foi descrever a morfologia de frutos, sementes e plântulas, além dos padrões anatômicos das plântulas, como contribuição para o conhecimento técnico-científico e produção de espécies amazônicas para o reflorestamento no Estado do Pará. Para isso, as descrições morfológicas seguiram os parâmetros de literatura especializada e as informações anatômicas técnicas usuais em anatomia vegetal. A espécie apresenta frutos do tipo legume, semente com pleurograma, as sementes possuem dimensões médias de 51,21; 21,33; 2,09 mm para comprimento, largura e espessura respectivamente, e as plântulas com eofilos e metafilos imparipenados, cordiforme, germinação fânero cotiledonar, epigea, foliácea. Os eofilos e metafilos apresentam epiderme unisseriada, feixe vascular colateral e dorsiventral. As características morfológicas podem auxiliar na identificação em campo, e na identificação de plantas jovens, auxiliando a produção de mudas da referida espécie, anatomicamente o hipocótilo não apresenta diferenças marcantes da raiz.Termos para indexação: identificação taxonômica, produção de mudas, tecnologia de sementes.

“…Soliman et al (2008) reported that the plant hairiness, flower color, pod wall thickness, cotyledon color, seed color, eye pattern and color, seed turgidity, and seed crowding are the most significant morphological attributes to distinguish among subgenera. The type of germination, the thigmotropic movements of hypocotyl and the stem, seedling architecture, and plant longevity were recorded by Ojeda et al (2013) on four species of Vigna Savi. These characteristics permitted us to distinguish the species and construct an identification key that could be useful for agronomic or floricultural purposes.…”

This work described the ten cowpea accessions using morphological, agronomical, and molecular characterization and select the desirable cowpea accession for improvement. Twenty-four characteristics were quantitative attributes. Data demonstrated by the Principal Component Analysis (PCA) increasing in some components associated with a decrease in eigenvalues, which gave its max at three factors. The PCA was arranged into three main components, which altogether valued at 63.40%. The matrix of PCA data is standardized. The coordinates were calculated for Bi-plot mapping using the Perceptual Mapping (PERMAP). Radiata accessions (1 and 2) fell into a group. Unguiculata accessions are classified further into two sub-groups. The accessions (4 and 6) dropped into a sub-group, and the rest gathered into another sub-group. The PCR-based marker technique, SSR markers, were also analyzed. These markers gave a total of 64 alleles with 51.32% of polymorphism. A total of 26 alleles were polymorphic. The most informative markers were EH03, EH09, EH06, and EH07. The SSR-phenogram had classified into two main groups at a distance of 0.34. The first one comprises accessions 1 and 2. The second fell further into two sub-groups at a distance of 0.52.

“…The obtained results were in agreement with Mahdy et al (2012) on Corchorus spp., Ojeda et al (2013) on four species of Vigna Savi and Selvakumar and Kumari (2015) on cowpea. These characteristics permitted to distinguish the cultivars and construct an identification key that could be useful for agronomic or floricultural purposes.…”

There is a great interest on the strategical plan in Egypt for the cultivation of a new crop used as source of natural sweeteners Stevia rebaudiana (Spanti) and (China-1) var. Stem nodal segments containing axillary buds were used as an explant and inoculated on Murashige and Skoog’s (MS) medium containing 3% (w/v) sucrose, 0.8% (w/v) agar supplemented with various concentrations of flurprimidol (flur.), paclobutrazol (PBZ) and thidiazuron (TDZ). In Spanti var. maximum number of branches (6.52) and (6.4) were obtained in MS medium supplemented with 0.12 mg/l flur. and 0.2 mg/l TDZ, respectively with an average of 56.4 and 36.67 leaves per plantlet, having an average shoot length of 6.40 and 6.52 cm, respectively. The best in vitro root induction (100%) was achieved on MS medium with 0.16 mg/l flur. with an average of 10.00 roots per plantlet and root length of 4.82 cm (Spanti var.). Furthermore, in China-1 var. (MS) medium supplemented with 0.16mg/l flur. induced the best morphological characteristics. The rooted plantlets from explant planted on (MS) medium supplemented with 0.16 mg/l flur. were successfully established in soil and grown to maturity at the survival rate of 100% in the greenhouse in (Spanti) and (China-1) var. As a result of anatomy, all studied growth regulators significantly enhanced the anatomical characters of stevia varieties leaf and stem.flur.at 0.16 mg\l surpassed, for instance, midvein and lamina thickness, length and width of leaf vascular bundle as well as stem diameter, xylem and phloem thickness. Our data revealed that the numbers of protein bands in most of treatments are bigger than which in the control.
