1. Straw management effects on sugarcane growth, nutrient cycling and water use in the Brazilian semiarid region
ABSTRACT It was evaluated how straw management modifies the development, growth, nutrient cycling and crop water productivity of sugarcane in the semiarid region of Brazil. The experiment was carried out using two plots with 5 ha each, being one without straw on the soil surface and one with 26 Mg·ha-1 covering the soil. Sugarcane growth and development and

2. Growth dynamics of the branching system in grasses: an architecture-based methodology for quantitative evaluation applied to two genotypes of Paspalum vaginatum
Resumo Foi estudada a dinâmica do crescimento dos caules aéreos de Paspalum vaginatum, uma gramínea de ampla distribuição. Com o objetivo de identificar características diferenciais quantitativas entre dois genótipos, as plantas foram cultivadas ao ar livre em vasos durante dois verões consecutivos. Os eixos de diferentes ramificações foram marcado

3. Sucrose concentration and volume of liquid medium on the in vitro growth and development of blackberry cv. Tupy in temporary immersion systems
RESUMO O uso de micropropagação de pequenos frutos como a amoreira-preta tem sido empregado devido à necessidade de obtenção de plantas com alta qualidade fitossanitária. A tecnologia de biorreatores tem sido usada para melhorar a eficiência na produção de mudas. Assim, o objetivo deste trabalho foi avaliar a melhor quantidade de meio de cultura e a

4. Phenotypic Characterization and Genetic Diversity of Sugarcane Varieties Cultivated in Northern Karnataka of India based on Principal Component and Cluster Analyses
Abstract: Sugarcane is a major commercial crop grown in India and across the world. Hence, several elite varieties have been developed now-a-days to overcome many obstacles including abiotic stresses and diseases. The present study was undertaken to screen genetic variation among twenty four sugarcane varieties that are commonly cultivated across Northern Ka

5. Fiber composition of a diversity panel of the world collection of sugarcane (Saccharum spp.) and related grasses
ABSTRACT The world collection of sugarcane (Saccharum hybrids. and related grasses (WCSRG) is an important source of genes for sugarcane and energycane breeding. The core collection or diversity panel of the WCSRG was created in Canal Point with 300 accession and 10 checks to evaluate its diversity. The fiber components of the species and accessions within t

6. Involvement of peroxidases in structural changes of barley stem
ABSTRACT The aim of this study was to investigate anatomical characteristics of barley (Hordeum vulgare L.) internodes and to reveal the connection with activity of guaiacol-peroxidases, their isoenzyme profiles, lignin, and cellulose content. Three lower internodes were sampled at elongation stage and differed in their anatomical features by showing that li

7. Biometric and chemical characteristics of sugarcane varieties for use as forage in limiting soil water conditions
ABSTRACT This study aimed to evaluate the biometric and chemical characteristics of five sugarcane varieties (RB 863129, RB 867515, RB 92579, RB 943365, and RB 98710) grown in a semi-arid climate for use as forage. The experiment was designed as randomized blocks, in a 5 × 2 factorial arrangement (five sugarcane varieties and two evaluation times, 407 and 4

8. In vitro callus induction and micropropagation of Thymus persicus (Lamiaceae), an endangered medicinal plant
Abstract This is the first attempt towards an efficient regeneration protocol for an endangered and valuable medicinal plant, Thymus persicus using in vitro callus induction and indirect organogenesis. Callus induction was performed on MS medium supplemented with different concentrations of NAA and 2,4-D, alone or in combination with BAP and KN. Maximum cal

9. Somatic embryogenesis and plant regeneration in Wedelia calendulacea Less. an endangered medicinal plant
In this work, plant regeneration via somatic embryogenesis was achieved from leaf and internode derived callus of Wedelia calendulacea, an endangered medicinal plant. Primary callus was induced by culturing leaf disc and internode explant on Murashige and Skoog medium supplemented with 2.0 mg L-1 of 2,4-D under light condition. Transfer of embryogenic callus

10. Organogenesis from in vitro-derived leaf and internode explants of Hoya wightii ssp. palniensis -a vulnerable species of Western Ghats
An efficient system was developed for indirect plant regeneration from in vitro-derived leaf and internode explants of Hoya wightii ssp. palniensis. Maximum percentage of the organogenic callus was obtained on MS medium supplemented with NAA (1.0 mg/l) and 2,4-D (2.0 mg/l). The best shoot bud induction was observed on MS medium with BA (1.0 mg/l) +IBA (0.5 m

11. Produção recombinante e caracterização funcional de uma legumaína de cana-de-açúcar
Plant legumains, also termed vacuolar processing enzymes (VPEs), are cysteine peptidases that play key roles in seed maturation, germination, senescence, stress response, programmed cell death during development and defense against pathogens. Despite the increasing number of reports on VPEs, most of studies are on dicotyledonous legumain and their role in se

12. Genetic architecture of purple pigmentation and tagging of some loci to SSR markers in pearl millet, Pennisetum glaucum (L.) R. Br.
This report describes the construction of integrated genetic maps in pearl millet involving certain purple phenotype and simple sequence repeat (SSR) markers. These maps provide a direct means of implementing DNA marker-assisted selection and of facilitating "map-based cloning" for engineering novel traits. The purple pigmentation of leaf sheath, midrib and
