It is a fact that the regions cultivate most maize crop do not have fully adequate technologies to measure productivity losses caused by irregularities in water availability. The objective of this study was evaluate physiological characteristics hybrids tolerant (DKB 390) and sensitive (BRS 1030) drought, at V5 growth stage under restriction, order understand mechanisms involved induction tolerance drought chitosan contrasting genotypes. Plants were cultivated pots greenhouse, 100 ppm...
Higher plants display different adaptive strategies in photosynthesis to cope with abiotic stress. In this study, photosynthetic mechanisms and water relationships displayed byJatropha curcasL. (physic nuts) andRicinus communisL. (castor bean), response variations environmental conditions, were assessed.R. communis showed higher CO2 assimilation, stomatal mesophyll conductance thanJ. curcas as light intensity intercellular pressure increased. On the other hand,R. was less effective control...
Este trabalho teve por objetivo avaliar o crescimento de plantas jovens nim-indiano (Azadirachta indica A. Juss.) submetidas a diferentes regimes hídricos. O delineamento experimental foi inteiramente casualizado, com sete tratamentos (100, 80, 60, 40 e 20% da capacidade pote, suspensão rega reirrigado). Avaliaram-se, semanalmente, altura, número folhas diâmetro do caule. Ao final experimento, as tiveram seus órgãos separados levados à estufa para obtenção matéria seca das folhas, caule,...
O objetivo do trabalho foi avaliar os efeitos de combinações nitrato e amônio no meio, na acumulação compostos nitrogenados carboidratos, presença ausência salinidade em plantas sorgo. Sementes genótipo CSF 20 foram cultivadas casa vegetação, solução nutritiva com três concentrações (100% NO3-: 0% NH4+, 75% 25% NH4+ 100% NH4+), salinidade. A reduziu a concentração nas folhas colmo, nos tratamentos 100:0 75:25. acumulou-se mais NaCl, colmo. Os teores aminoácidos livres totais não se...
The objectives of this study were to perform the physicochemical characterization chitosan, evaluate its effects on germination, early growth, root anatomy and cell cycle two maize hybrids. hybrids DKB 390 VTPRO (transgenic) used. DKB390 is from Monsanto, event number 89034, which expresses proteins Cry1A105 Cry2AB2. For physico-chemical following analyzes performed:, elemental analysis, total ash, infrared absorption spectroscopy, nuclear magnetic resonance, powder X-ray diffraction,...
The yield and cause effect relationships of green-ear production components hybrids cultivated in reduced spaced environments were investigated aiming to increase the green ear harvest, as well identify main characteristics that contribute most productivity. Four row spacings evaluated using three commercial hybrids. experiment lasted months evaluated: plant height (PH) insertion (EIH), leaf area (LA), stem diameter (SD), total number ears, yield, with straw without straw, ears (YES) (YEWS),...
Understanding how water stress impacts the growth and physiology of young bamboo plants is important to define management strategies successful field establishment species. In this study, Dendrocalamus asper were evaluated determine effects availability in initial phase physiological behavior species under these conditions. Four deficit conditions (0%, 25%, 50% 100% capacity) applied a completely randomized design. The grown pots tunnel-type greenhouse environment. At 7 30 days imposition...
