1. Linear relationships between biometric variables in lettuce seedlings
ABSTRACT Seedling production is an important step in growing vegetables. The study of relationships between variables has applications in practically all areas of study and is useful in identifying relationships among quality variables in vegetable seedlings. Thus, this work aims to estimate linear relationships between biometric variables in lettuce seedlin

2. Productivity and postharvest durability of Heliconiaceae grown in full sun in the Midwest region of Brazil
ABSTRACT Flower stems of the Heliconiaceae family are gaining more and more space in the Brazilian market of ornamental plants and further knowledge about quality, productivity, and postharvest management is necessary. The objective of the present study was to evaluate heliconiaceae cultivated in full sun in the central-west region of Brazil in terms of agro

3. Inbreeding depression and genetic variability of populations for green maize production
ABSTRACT The production of green maize is considerable important for various regions of Brazil. It is vital that breeding programs of public institutions seek to meet the needs of this market sector, which has a relevant social role, mainly on small properties. The aim of this study was to estimate the inbreeding depression and the genetic components (m + a

4. Genetic parameters estimation in common bean under weed plant competition
ABSTRACT The present study aimed to estimate genetic parameters of 20 common bean genotypes, commercial and regional bean on weed interference. The agronomic characters analyzed were: average stem diameter (ASD); average plant length (APL); number of pods per pot (NPP); number of locules per pod (NLP); number of grains per pod (NGP); percentage of empty locu

5. A crop pest species of Cyclocephala Dejean (Coleoptera: Melolonthidae: Dynastinae) misidentified for over twenty years in Southern Brazil
ABSTRACT A common white grub species associated with a wide range of crops in Southern Brazil has been named as Cyclocephala flavipennis Arrow for over twenty years. This work aimed to revise the identity of this species based on the study of primary types, identified material collected in previous works and descriptions on literature. The confirmed name for

6. Fruits of neotropical species of the tribe Malveae (Malvoideae - Malvaceae): macro- and micromorphology
ABSTRACT Fruit morphology of the tribe Malveae has been discussed since the first taxonomic classifications of Malvaceae. The fruits are schizocarps, with some genera possessing an endoglossum. Besides morphological variation in the endoglossum, other differences include the number seeds per locule and ornamentation of the exocarp. An in-depth study of the f

7. Image phenotyping of lettuce germplasm with genetically diverse carotenoid levels
ABSTRACT Developing biofortified foods such as lettuce is a frequent goal of breeding programs. One obstacle to the success of these efforts is the high temporal and financial cost of determining leaf constituents. Image phenotyping has been increasingly used in crop breeding, but not in lettuce breeding. Until now, the use of image phenotyping to indirectly

8. Taxonomic relevance of leaf anatomy in Banisteriopsis C.B. Rob. (Malpighiaceae)
ABSTRACT We describe the leaf anatomy of 42 of the 60 species of the genus Banisteriopsis, one of the largest and most diverse genera of Malpighiaceae in the Cerrado domain. Our aim was to identify anatomical leaf characters useful for the taxonomy and systematics of this morphological diverse genus. Expanded leaves from herbarium specimens were rehydrated a

9. O JOGO DE REALIDADE ALTERNADA CURTO (SHORT ARG) COMO ESTRATÉGIA DE DISCUSSÃO DE CONCEITOS QUÍMICOS EM NÍVEL SUPERIOR
This paper presents the application of a Short ARG built to be applied in a single class, instead of a longer interval, as it is common in strategies such as ARG. ARGs are games based on role-playing experiences that involve role playing using a particular place, in this case, two classrooms and an education lab. Whereas ARG’s characters are the participan

10. THEORETICAL CALCULATIONS ABOUT THE THERMAL STABILITY AND DETONATION CHARACTER OF NITRAMINO-SUBSTITUTED PYRROLE
A series of nitramino-derivatives of pyrrole were designed through introducing the nitramino group into pyrrole ring to look for high-energy-density compounds. The molecular stabilities are explored thoroughly based on the calculated heats of formation, bond dissociation energy, and bond order at the B3PW91/6-311+G(d,p) level. The results indicated that the

11. RNA editing in the chloroplast of Asian Palmyra palm (Borassus flabellifer)
Abstract We have identified 46 RNA editing sites located in 20 chloroplast (cp) genes of Borassus flabellifer (Asian Palmyra palm), family Arecaceae, and tested these genes for supporting phylogenetic study among the commelinids. Among the 46 sites, 43 sites were found to cause amino acid alterations, which were predicted to increase the hydrophobicity and t

12. Genome-Wide Assessment of Putative Superoxide Dismutases in Unicellular and Filamentous Cyanobacteria
Abstract Cyanobacteria are photoautotrophic prokaryotes capable to grow in diverse ecological habitats, originated 2.5-3.5 billion years ago and were first to produce oxygen. Since then superoxide dismutases (SOD) acquired great significance due to their ability to catalyze detoxification of byproducts of oxygenic photosynthesis i.e. superoxide radicals. In
