Altura de corte de capim Elefante cv. Cameroon em Rondônia. Infoteca-e
GONÇALVES, C. A.; COSTA, N. de L..
Resultados de pesquisa demonstraram que em Ouro Preto e Ariquemes-Rondonia, as maiores producoes de MS sao obtidas com corte a 10 e 20cm e 25 e 30cm acima do solo, respectivamente, enquanto que em Presidente Medice-RO a altura de corte nao afetou a producao de MS, contudo, visando asssegurar maior persistencia da capineira, recomenda-se corte acima de 10cm. Cortes e baixa altura (5 e 10cm) implicam na reducao dos stands e em incremento da infestacao de invasoras. Nos tres locais, a altura de corte nao influenciou os teores de PB da forragem.

Colonization-related functional traits of plants in a 50-hectare plot of secondary tropical forest Acta Botanica
Candido,Helder Marcos Nunes; Miazaki,Ângela; Pontara,Vanessa; Bueno,Marcelo Leandro; Solar,Ricardo; Gastauer,Markus; Meira-Neto,João Augusto Alves.
ABSTRACT The growth-survival trade-off hypothesis states that functional traits of stem, wood, leaves and fruits govern acquisitive and conservative strategies of plant species that grow/survive differently in forests. We aimed to determine whether heterogeneity during the colonization of a secondary Atlantic Forest fragment causes differences in colonization-related traits and determines taxonomic composition of subplots. A total of 5,078 subplots were censused with leaf and fruit traits and height measurements being determined for each tree of each species, and with averaged-abundance-weighted values calculated for each subplot. A dendrogram was generated from the taxonomic composition of subplots using Sorensen similarity and UPGMA clustering. A total...

Dry matter production and partitioning of maize hybrids and dwarf unes at four plant populations Ciência Rural
Sangoi,Luis; Salvador,Ricardo.
This experiment was conducted in Ames, Iowa, USA, to compare dry matter accumulation patterns of maize genotypes contrasting in height and leafiness, and to test whether reduction in plant height an leaf number through the use of dwarfing genes or earliness can improve grain dry matter allocation. Five plant genotypes were tested: a full season hybrid adapted to central lowa (NK 4525), a short season hybrid adapted to northern Minnesota (C1070), and three dwarf lines (156-A, 302-E and I17- A). The dwarves contained, respectively, the homozygous, independent, recessive dwarfing genes d3, d1 and br2. Each genotype was sown at four plant populations: 25, 50, 75 and 100.000 plants. ha-1. Hybrids had the greatest rates of decrease in total biomass and grain dry...

Effect of planting density on green ear yield of maize cultivars bred in different periods Horticultura Brasileira
Silva,Paulo Sérgio L e; Duarte,Severino R; Oliveira,Fábio Henrique T de; Silva,Júlio César do V.
Corn cultivation in the Northeast region of Brazil is characterized by a great diversity of production systems, ranging from large companies (modern cultivars and relatively high planting densities) to small farms (family agriculture, traditional cultivars, and low planting densities). In the present work we evaluated the effects of planting density (30; 40; 50; 60; or 70 thousand plants ha-1 - TPH) on green ear yield of cultivars Centralmex (traditional) and AG 510 (hybrid). Different densities were achieved by maintaining 1.0 m between rows and varying the spacing between pits, within the row. Cultivars and planting densities were combined in a factorial scheme, arranged in a random block design with four replicates and four 6 m long row plots. The...

Evaluation of morphological characteristics in Venezuelan maize (Zea mays L.) genotypes under drought stress Scientia Agricola
Camacho,R.G.; Caraballo,D.F..
A greenhouse experiment was carried out to evaluate the responses among 10 maize (Zea mays L.) genotypes under drought stress. Seeds were planted in washed sand in plastic pots. The research was established in a completely random design with ten treatments and three replicate pots. The plants were harvested four weeks after sowning, and leaf area per plant (LA), root volume (RV), longest root length (LRL), plant height (PH), fresh (RFW) and dry weight (ROW) of roots, shoot dry weight (SOW), RDW/SDW ratio, and total dry matter production (TDM) were determined. Significant varietal differences for all characters were found, except for LRL. The data obtained allowed to identify Cargill-163 as a poor genotype at low water supply. Danac-3006, FM-6,...

Growth of lulo (Solanum quitoense Lam.) plants affected by salinity and substrate Rev. Bras. Frutic.
Flórez,Sandra Liliana; Lasprilla,Diego Miranda; Chaves,Bernardo; Fischer,Gerhard; Magnitskiy,Stsnislav.
The effects of 0, 30 and 60 mM NaCl and substrates (red peat, sand or 3:1:1 [w/w] mixture of peat, sand, or soil) on vegetative growth of lulo, an Andean fruit species, during 12 weeks were studied. The experiment was carried out by using 2000 cm³ of polypropylene plastic pots under greenhouse conditions. Plant height, number of leaves and nodes, leaf area, total plant dry matter (DM), and shoot/root ratio were evaluated. With the increase of salt concentration, the plant height, the number of leaves and nodes, the leaf areas and plant dry mass DM decreased, whereas shoot/root ratio increased. Sand grown lulo plants were most affected by salinity and presented total mortality at 60 mM NaCl. On the other hand, plants held either in peat or in substrate...

Growth of seven perennial plant species adapted to the Brazilian Semi-Arid. Abstract - Measuring plant height (y) and canopy diameter (x) in trees may not be an easy task, but stem diameter (z) can be more easily evaluated. This work's objective was two-fold: evaluate the growth of species adapted to the Brazilian Semi-Arid Region in the first two years of age, and obtain linear equations to estimate y and x from z, in those species. A random block design with four replications was employed. The values for x, z, and y were measured biannually from October/2003 to March/2005. Prosopis juliflora and Mimosa caesalpiniaefolia showed the highest stem diameter and plant height values, respectively, and both showed the highest canopy diameter. In the equations to...

Growth, phenology, and seed viability between glyphosate-resistant and glyphosate-susceptible hary fleabane Bragantia
Kaspary,Tiago Edu; Lamego,Fabiane Pinto; Cutti,Luan; Aguiar,Adalin Cezar de Morais; Rigon,Carlos Alberto Gonsiorkiewicz; Basso,Claudir José.
ABSTRACT Glyphosate is the herbicide most used worldwide. In cropping systems that rely on repeated applications of glyphosate or cultivate genetically modified soyabean crop, there are numerous cases of glyphosate resistant weeds, including Conyza bonariensis. Differences among competitive ability of Conyza spp. have been found. However, little information is available on the fitness costs related to glyphosate resistance in Conyza bonariensis. We evaluated growth, phenology, and seed viability of glyphosate-resistant (GR) and glyphosate-susceptible (GS) Conyza bonariensis from Brazil, in 2012 (fall/winter) and 2013 (spring/summer). When grown alone, in pots, C. bonariensis GR biotype developed more rapidly than the GS biotype, as evidenced by their...

High level of copper application to soil and leaves reduce the growth and yield of tomato plants Scientia Agricola
Sonmez,Sahriye; Kaplan,Mustafa; Sonmez,Namik Kemal; Kaya,Harun; Uz,Ilker.
Copper-containing fertilizers, fungicides and bactericides are extensively used in greenhouses in Turkey. Informations on effects of these applications to plants are scarce. The aim of the present study was to investigate effects of Cu application to a calcareous soil and to leaves on the yield and growth of tomato plants. Cu was first applied to soil as CuSO4.5H2O in three different levels (0, 1000, and 2000 mg Cu kg-1) and then to leaves in three different frequencies (no application, biweekly and weekly) using two cupric fungicides (Cu oxychloride, and Cu salts of fatty and rosin acids) in pot experiments carried out in a computer-controlled greenhouse. Total yield, fruit number, dry root weight and plant height decreased with increasing Cu application...
