| The Azivash plant was cultivated at densities of 20, 27, 40 and 80 m-2 and three irrigation intervals of 6, 12 and 18 days with three replications using a randomized complete block design. Cultivation was considered in a row and row spacing of 25 cm was used. Plant spacing on the row was respectively 5, 10, 15 and 20 cm. At harvesting time when the plant height was about 50 cm, the components of plant height (cm), number of leaves per plant (number), new plant amount of yield (kg ha-1), number of branches per plant (number), leaf area index (leaf area), fresh weight of leaves and stems (kg ha-1), dry weight of leaves and stems, and total dry matter per hectare (kg ha-1) were determined. The results showed that both components of the irrigation and plant... |

| Abstract Various studies have been undertaken to evaluate the effect of polymer-based encapsulation on performance of plant growth promoting microorganism. However there is no systematic analysis about the performance of these microorganisms when encapsulated in a polymer-based matrix. Relevant published papers were retrieved by conducting searches in Google Scholar, Only Library, Science Direct, Springer Journal, Taylor & Francis and Wiley Online Library. An examination of 117 articles was carried out and of those only 11 satisfied our criteria for inclusion into the meta-analysis. From these articles, we selected 41 cases to be evaluated. We used as keywords “microcapsules”, “capsules”, “microorganisms”, “growth”, “promoting”, “germination”... |

| ABSTRACT In the present study, the potential of seaweed liquid fertilizer (SLF) of marine algae Enteromorpha intestinalis was evaluated for its effect on seed germination, yield, biochemical parameters and pigment characteristics of Glycine maxE. intestinalis was collected form Mandapam coast of Gulf of Mannar, Tamil Nadu, and the dried seaweeds were used for the preparation of SLF. G. max seeds were germinated with four different concentrations (20, 40, 60, and 100%) of SLF; its growth and yield parameters were evaluated and compared with chemical fertilizer and control. The morphological and bio-chemical parameters such as seed germination (100%), root (6.6cm) and shoot length (5.4 cm), carbohydrates (0.098 mg/g), protein (0.56 mg/g), pigment (0.444 mg/g... |

| The objective of the experiment was to identify the morphological alterations in corn genotypes in response to aluminum toxicity in the soil. A complete randomized block design with five replications was used. The a factorial scheme was composed of two corn genotypes (C525M - tolerant, and HS701B - sensitive) and two neutralization levels (0% and 100% of aluminum saturation). The evaluations were performed at six leaf and 10-11 leaf growth stages, emergence of the "stigma-style", and the physiological maturity. The presence of toxic aluminum didnt significantly reduce diameter and height of stem, leaf area, dry matter of aerial parts, total dry matter and yield. Stem diameter, leaf area, dry matter of root, dry matter of aerial parts, total dry matter and... |

| The γ-aminobutyric acid (Gaba) is a non-protein amino acid found in prokaryotes and eukaryotes. Its role in plant development has not been fully established. This study reports a quantification of the levels of endogenous Gaba, as well as investigation of its role in different stages of somatic embryogenesis in Acca sellowiana Berg. (Myrtaceae). Zygotic embryos were used as explants and they were inoculated into the culture medium contained different concentrations of Gaba (0,2, 4, 6, 8 and 10 µM). The highest concentrations of endogenous Gaba were detected between the third and nine days after inoculation, reaching the value of 12.77 µmol.g-1FW. High frequency of somatic embryogenesis was observed in response to 10 µM Gaba. This treatment also resulted in... |

| This study attempted to clarify the effects of dark, light and ethylene on plant growth and endogenous levels of indole-3-acetic acid (IAA), cytokinins and abscisic acid in Catasetum fimbriatum. Dark-incubation fully inhibited root and pseudobulb formation as well as leaf growth, but favored shoot elongation. The results of continuous and active growth in dark-incubated shoots (stolons) were induced by strong apical meristem sink activity and by the significantly increased levels of cytokinins in shoots. In fact, shoot length, cytokinin and IAA levels in dark-incubated shoots were about twice as great as for those grown under light conditions. Moreover, the total cytokinin level in shoots of C. fimbriatum under light conditions without ethylene was... |

| Avocado seeds present high size variability. Larger seeds, such those of the ‘Esther’ variety, are preferred when nurse seeds are used. Even though they are considered recalcitrant seeds, they are stored for propagation. The aim of this study was to evaluate the combined effect of three storage periods and three sizes of ‘Esther’ avocado seeds on vigor, in terms of electrolyte leakage, and seedling length and diameter. The experiment was conducted using a completely randomized factorial design. The factors were time in storage (10, 30 and 100 d at 5 °C and 80% relative humidity) and seed size (small, medium and large). Electrolyte leakage was evaluated as a measure of seed vigor, growth and later development of the... |

| ABSTRACT Although there are evidences that the proper supply of mineral nutrients to plants relieves water stress, little is known on the approach of how the drought affects the absorption and accumulation of nutrients by distinct sugar cane genotypes, or in different parts of a same plant. Thus, the objective of this study was to determine the content and accumulation of N, P and K in the aerial part of plant from three genotypes of sugar cane, submitted to three water potentials in the soil, and check the relationship of these variables with the tolerance of plants to prolonged drought. In order to access this objective, an experiment under greenhouse conditions, comprised by a fatorial 3 × 3, in a randomized block design, and four replicates was carried... |
