Abstract Background: Plant root-knot nematode (RKN) disease is a serious threat to agricultural production across the world. Meloidogyne incognita is the most prominent pathogen to the vegetables and cash crops cultivated. Arachis hypogaea can effectively inhibit M. incognita, but the underlying defense mechanism is still unclear. Methods: In our study, the chemotaxis and infestation of the second-stage juveniles (J2s) of M. incognita to A. hypogaea root tips were observed by the Pluronic F-127 system and stained with sodium hypochlorite acid fuchsin, respectively. The transcriptome data of A. hypogaea roots with non-infected or infected by J2s were analyzed. Results: The J2s could… More >

Abstract Cytotoxic properties of plant extracts and drugs being developed for cancer treatment are usually evaluated by a variety of in vivo and in vitro tests carried out in animal or plant based models. In the present study we have evaluated the possibility of using the germinating mung beans (Vigna radiata), for rapid and inexpensive screening of drugs exhibiting cytotoxic properties. Mung beans were allowed to germinate either in tap water or in different drug solutions, and parameters like percent germination, increase in radicle length, change in seedling weight and mitotic index of apical root meristems were determined at two time… More >

Abstract Cologania broussonetii (Balb.) DC. stands out as valuable perennial, native forage that grows in northwestern Argentina, Cordoba hills and San Luis Province. The objectives of this study were to establish the vegetative and reproductive structures in function of the strategies and survival tactics of Cologania broussonetii. The specimens were collected in the Pan de Azúcar loaf mountain, Córdoba, and in the experimental plots of the FCA, UNC, and were then deposited in the Herbarium ACOR and in the Seed Collection. Seedlings were obtained from germination assays. Cross section cuts were performed on the survival structures of adult plants, and on… More >

Abstract We evaluated the possibility of making jam (product A) and simile sweet potato jam (product B) from the edible pulp of the fruits of Geoffroea decorticans. The first step was the chemical characterization of the flour (pulp) highlighting their carbohydrate (85.6%), protein (9.4%) and mineral (4.2%) concentrations. Sucrose (29.5%), glucose (3.80%) and fructose (5.30%) levels were quantified using gas chromatography. Contents of protein (5.7%), minerals (3.4%), dietary fiber (0.97%), sucrose (46.8%), glucose (1.9%) and fructose (2.4%) were very good in jam. The simile sweet potato jam had low calories (140 Kcal/100g) and provided protein (4.6%). During the 12-month-storage period, the… More >

Abstract Crotalaria juncea L. (Fabaceae) is an annual herbaceous species native to India. Their seeds have polymorphism in the seed coat color and different seed sizes. Seeds were grouped according to their seed coat color into uniform (dark gray seeds) and variegated (brown mottled seeds), to evaluate the vigour of C. juncea seed morphotypes. They were also classified into small (< 5mm length) and big seeds (>5 mm length). The 1000 seed weight, germination percentage, length and seedling dry weight, electrical conductivity and field emergence were evaluated. The results showed that uniform seeds had greater weight than those variegated of the… More >

Abstract We studied the growth habit and root anatomy on two species of the Macroptilium genera, Fabaceae. These species, potential forages, are native to the Northwest Provinces in Argentina. The aims of this paper were to determine the survival capacity of the study species relating its growth habit and persistence with morphological and anatomical features. Root samples were collected and cut using either a microtome or by hand, at varying distances from the root tip. Cuts were examined under a light microscope, and with scanning electron microscopy (SEM) using staining techniques. Macroptilium bracteatum and M. erythroloma are perennial herbs. Aerial parts… More >

Abstract After a fire event, germination of seeds with hard coats can be enhanced. In the present study, we investigated whether germination of Mimosa bimucronata (DC.) Kuntze (Fabaceae) seeds, which present hard coats, is increased after fire, even though these trees usually occur in damp areas, where fire is a transient event. Fire events were manipulated in trays filled with soil covered with different amounts of dry grasses, characterizing three treatments: a) 0g (control group); b) 300g, and c) 450g of dry grass. Burning treatments were applied to seeds positioned either on the soil surface or buried in the soil. Germination… More >

Abstract The genus Vicia L. belongs to the tribe Vicieae of the Fabaceae family. The genus includes about 190 species, from which about 40 species have economic importance. Some of them are food crops, but more than a dozen are forage plants. In this study, leaves of Vicia species from China, USA and Argentina were examined using stereo-microscopy and light microscopy. We determined macro- and micro-morphological characteristics that could be of taxonomic use. Forty eight characteristics of each taxon were determined including petiole and tendril length; leaflets number, length, width, shape, apex, base; blade surface, trichome shape, type, base and length;… More >

Abstract In arid and semi-arid ecosystems, increasing and irreversible degradation in areas of high conservation value has prompted the search for various solutions, such as rehabilitation and ecological restoration. To implement these strategies, it is essential to solve critical issues affecting the establishment of plants in the field and the production of seedlings in nursery gardens. In the present work, the following pre-germination treatments were evaluated for the species Senna arnottiana and S. kurtzii, endemic to the Patagonian steppe (Payunia): (1) Immersion in water at 80 °C for 5 minutes; (2) Immersion in water at 80 °C for 10 minutes; (3)… More >

Abstract The effect of scarification methods and silver nanoparticles on plantlets growth were tested on seeds of plants belonging to the Fabaceae family (Prosopis laevigata, Acacia farnesiana and Erythrina americana), which are predominant species in semi-arid ecosystems in Mexico. The scarification methods consisted in using coarse sand paper and two different concentrations of sulphuric acid (H₂SO₄ 98% and H₂SO₄ 50%); immersion of seeds in distilled water was used as a control. The percentage of germination was calculated and the Kotowski´s coefficient was determined. After scarification, the seeds were immersed in silver nanoparticles solutions at different concentrations i.e., 100 mg/L, 500 mg/L… More >
