Lignan Glycosides

Lespedeza cuneata (Fabaceae), known as Chinese bushclover, has been used in traditional medicines for the treatment of diseases including diabetes, hematuria, and insomnia. As part of a continuing search for bioactive constituents from Korean medicinal plant sources, phytochemical analysis of the aerial portion of L. cuneata led to the isolation of two new lignan glycosides (1,2) along with three known lignan glycosides (3–7) and nine known flavonoid glycosides (8–14). Numerous analysis techniques, including 1D and 2D NMR spectroscopy, CD spectroscopy, HR-MS, and chemical reactions, were utilized for structural elucidation of the new compounds (1,2). The isolated compounds were evaluated for their applicability in medicinal use using cell-based assays. Compounds 1 and 4–6 exhibited weak cytotoxicity against four human breast cancer cell lines (Bt549, MCF7, MDA-MB-231, and HCC70) (IC50 < 30.0 μM). However, none of the isolated compounds showed significant antiviral activity against PR8, HRV1B, or CVB3. In addition, compound 10 produced fewer lipid droplets in Oil Red O staining of mouse mesenchymal stem cells compared to the untreated negative control without altering the amount of alkaline phosphatase staining.

Carrot seeds exhibit irregular vigor due to the wide blooming period of the crop. Results from germination tests are insufficient to evaluate the physiological potential. Thus, vigor tests are used in combination with germination tests. The objective of this work was to evaluate the quality of carrot seeds from different umbel order and the electrical conductivity under different temperatures and imbibing periods. Carrot seeds from cultivar Brasilia were used to perform the experiments. Content of water, the first and the final score of the germination test, index of germination rate, and length of roots and of the aerial portion were determined in the initial characterization. The electrical conductivity test was completed with replicates containing 50 seeds, in 25 mL deionized water at 20, 25 and 30oC. Evaluations were performed with 2, 4, 6, 8, 12 and 24 hours of imbibing period. The experiment was accomplished under a completely random statistical design. The quality of carrot seeds varied according to the umbel order. Seeds of secondary umbels showed better physiological quality. The electrical conductivity test is efficient to evaluate the vigor of carrot seeds with 8 hours of imbibing period at 25°C.

The apical and floral development of Claytonia caroliniana var. caroliniana has been studied concurrently with soil temperature, in a sugar maple forest of the Stoneham mountain, Québec. Apical cellular activity begins early in May, while the flowering stems of the year are present. At the beginning of July, external apical development becomes visible. In the first days of August, 9 months before flowering, the foliar and floral structures of the next year are already present in the soil. Meiosis takes place at the beginning of October and first pollen mitosis follows shortly after, in the middle of the same month. From that time, well developed individuals, without chlorophyll, are present just under the litter. They can occasionally turn green and reach the upper surface of the litter in November or December, where they will spend wintertime under the snow, at a temperature oscillating between 0 and −4 °C. This behaviour is quite close to the survival strategy of hemicryptophytes. The active epigeous growth period begins in the middle of April, with the melting of snow. Second pollen mitosis and flowering take place at this time, rapidly followed by seed setting, dissemination, and destruction of the aerial portion of the plant. Cytoecological investigations to study possible influence of environmental factors on chromosomal anomalies in primordia should thus be conducted during the year preceding the flowering of Claytonia.

The objective of this work was to verify the influence of light environments combined with rhizobia inoculation on cowpea growth and productivity. A completely random design was used in a 4x4 factorial scheme, with four light environments, four nitrogen sources and eight replicates in split plot parcels. Light environments were set by means of photo-conversion and thermo-conversion nettings (Aluminet®, red net and black net) and control treatment without shading (full sun). Nitrogen sources were constituted by the strains INPA 03-11B - SEMIA 6462 (Bradyrhizobium elkanni) and UFLA 03-84 - SEMIA 6461 (Bradyrhizobium viridifuturi), and two control treatments: with 70 kg ha-1 of mineral nitrogen and without N. Plant height, indices of chlorophyll a, b and total chlorophill, the number of leaves, number of nodules, dry matter of nodules, dry matter of the aerial portion, dry matter of roots and total dry matter, relative efficiency, gathering of nitrogen in the aerial portion, number, length and matter of pods per plant and dry matter of 100 grains, were evaluated. . There was interaction between light conditions and nitrogen sources for the number of nodules. Individual effect was observed in all other variables. Strain INPA 03-11B was able to promote higher nodulation in cowpea plants in light environments under full sun and Aluminet and the strain UFLA 03-84 only under full sun conditions. However, the efficiency of diazotrophic bacteria to promote vegetative growth, nitrogen gathering and production was not influenced by different light environments. Thus, full sun cultivation is recommended, independently of the nitrogen source used.

Different Growth Stages

Retention, absorption, translocation, and metabolism of 2,4-D [(2,4-dichlorophenoxy)acetic acid] by common waterplantain (Alisma trivialePursh. # ALSPA) at three growth stages were investigated to determine the basis for differential susceptibility of common waterplantain at different growth stages. Plants in the five-leaf and scape elongation stages retained more 2,4-D than plants in the early flowering stage. Absorption of14C-2,4-D by the flower stalk was less than absorption by the treated leaves regardless of growth stage. The majority of the absorbed14C translocated out of the treated plant part was recovered in the aerial portion of the plant younger than the treated leaves or in the corm, with greater movement of14C into the corm at the older growth stages. Metabolism of14C-2,4-D did not differ among the growth stages. The results suggest that the greater sensitivity of common waterplantain at the scape elongation stage to 2,4-D is due to greater translocation to the corm when compared to the five-leaf stage, and greater retention when compared to the early flowering stage.

ABSTRACT The objective of this work was to evaluate the initial growth of Bauhinia variegata L. when inoculated and fertilized with different proportions of organic compost. The experiment was performed in greenhouse in a completely random factorial (2 x 5) + 1 design, with 9 replicates, constituted by the presence or absence of inoculation, five proportions of organic compost:soil (0:100, 20:40, 40:60, 60:40 and 80:20; v/v) and one additional treatment with chemical fertilization without inoculation. Ninety days after sowing, the plant height, stem diameter, number of leaves, radicular length, dry mass of the aerial portion, dry mass of roots, total dry mass, Dicksosn's quality index (IQD), contents of nitrogen and carbon and the C/N ratio of the dry mass of the aerial portion, were evaluated. The inoculation with diazotrophic bacteria stimulated growth in height, stem height/diameter ratio, dry mass of the aerial portion, dry mass of roots, total dry mass and the foliar contents of nitrogen and carbon in seedlings of B. variegata L. Seedlings grown using organic compost showed better development when compared to seedlings grown only in soil with or without chemical fertilization. Seedlings grown with formulated substrate at a proportion of 16:84 (organic compost:soil + inoculation) exhibited higher IQD, therefore, this constitutes the recommended proportion for production of B.variegata L. seedlings.

ABSTRACT The genus Melocactus (“cabeça-de-frade”) comprises 32 species in Brazil, of which M. glaucescens and M. paucispinus are threatened with extinction. The present work evaluated the effects of different concentrations of Murashige & Skoog (MS, MS/2 and MS/4) culture medium and sucrose (15 g L-1 and 30 g L-1) on in vitro seed germination and plant growth of M. glaucescens and the efficiency of sterilization with sodium hypochlorite (NaOCl) on in vitro seed germination and plant growth of M. glaucescens when using seeds and M. glaucescens and M. paucispinus when using apical segment of cladode. In M. glaucescens, the final germination at the different MS and sucrose concentrations varied between 53.5 and 68.1% and the best results for in vitro growth were observed with the lowest mineral salt (MS/2 and MS/4) and sucrose (15 g L-1) concentrations, with lengths of the aerial portion of 9.70 and 10.76 mm, respectively. There was no difference in seed germination and plant growth in chemical and autoclave medium. It is concluded that the use of chemical sterilization with NaOCl at low concentrations of salts (MS/2 and MS/4) and sucrose (15 g L-1) are quite advantageous for producing ornamental plants germinated in vitro and/or apical segment of cladode of M. glaucescens andM. paucispinus, representing a reduction of costs for in vitro cultivation of this species.

ABSTRACT Inoculating crops with diazotrophic bacteria constitutes a feasible biotechnological tool to reduce or even avoid the use of nitrogen fertilizers and to improve the nutritional status of crops. However, the potential use of such technology is limited due to the lack of studies in diverse vegetable crops. We evaluated the production of chicory (Cichorium intybus) in response to inoculation with diazotrophic bacteria in two soil classes. The experiments were performed under greenhouse conditions and under a completely randomized design. The treatments were constituted by strains UFRB FA34C2-2, UFLA 03-84 and INPA 0311B, and two control treatments (devoid of bacterial inoculation and with and without nitrogen fertilization). Two experiments were carried out, one using a soil classified as a dystrophic yellow Latosol (Oxisoil) and one using a Quartsandy Neosol (Typic Quartzipsamment). Chlorophylls a, b and total; plant height; number of leaves; dry mass of the aerial portion; dry mass of roots; total dry mass; effectiveness; efficiency in addition to N and P gathering in the aerial portion, were evaluated 60 days after seeding. The inoculation with diazotrophic bacteria resulted in adequate production when compared to the control treatment without nitrogen fertilization and without inoculation. Diazotrophic bacteria showed potential supplying nitrogen to chicory plants and spare the use of nitrogen fertilization in both soil classes. The strain INPA 0311B, recommended for cowpea, promoted vegetal growth and increased the dry weight of the aerial portion in chicory, under both dystrophic yellow Latosol (Oxisoil) and Neossolo Quartzarênico (Typic Quartzipsamment), when cultivated under greenhouse conditions.
