A field experiment was conducted at the research field of Sher-e- Bangla Agricultural University, Dhaka during the period from December 1, 2016 to January 11, 2017 to investigate the effect of gibberellic acid (GA3) on vegetative growth, morphological attributes and foliage (leaf) yield of coriander (Coriandrum sativum L.). The experimental treatments consisted of eight different doses of GA3 viz., 0 (distilled water spray), 5, 10, 15, 20, 25, 30 and 35 ppm. The variety Rosina (Pahuja Co., India) was used as planting material and different doses of GA3 were applied on the plants at 25 and 30 days after sowing. The experiment was laid out in Randomized Complete Block Design with three replications. GA3 had significant effect on vegetative growth, morphology, foliage yield and yield contributing characters of coriander. Plant height, number of leaves plant-1, leaf length, plant spread and single plant weight were found maximum from the application of GA3 at 20 ppm, which was closely followed by 25 ppm GA3. Application of GA3 at 20 ppm produced the highest weight of foliage m-2. A strong positive correlation of foliage yield was observed with plant height, number of leaves plant-1, leaf length, plant spread, single plant weight and weight of foliage m-2. Application of GA3 at 20 ppm gave maximum foliage yield (9.34 t ha-1) which was followed by GA3 at 15 ppm (8.46 t ha-1) and 25 ppm (8.06 t ha-1), and the minimum foliage yield was recorded from control (distilled water spray) (4.90 t ha-1). Application of GA3 at 20 ppm increased foliage yield over control by 47.54 %. A quadratic relationship between applied GA3 concentration and foliage yield was found; the regression equation was y = 4.87 + 0.375x – 0.009x2 from which it came up to be optimum dose of GA3 as 20.83 ppm.Res.

This study aimed at estimating the wood ash as a corrective and fertilizer in the safflower crop. This study was done with respect to the development, growth, and production of safflower in response to the wood ash doses applied to Oxisol of the Brazilian Cerrado biome. Adopting the completely randomized design and using five wood ash doses (0, 8, 16, 24, 32 g dm-3) and six replicates, the experiments were performed under greenhouse conditions. Each experimental unit included a 2 dm3 pot, filled with soil that had been incubated earlier for 30 days. The variables studied included soil pH, plant height (cm), stem diameter (mm), number of leaves (plant-1), SPAD index, internal and external diameters of the chapters (cm), number of chapters (plant-1), chapters dry mass (g pot-1), shoot dry mass (g pot-1), volume (cm3 pot-1) and root dry mass (g pot-1) Analysis of variance and subsequent regression test were performed for all the data using SISVAR software, at 5% probability for both. The variables internal and external diameter of the chapters and root volume showed no significant differences. The soil pH revealed a significant effect of the wood ash application tending towards linearity, as did the other vegetative variables of plant height, stem diameter, number of leaves and SPAD index. The productive constituents exhibited improved development when the wood ash was applied to the soil in doses of around 24 g dm-3 or more.

ABSTRACT Gladiolus is an important cut flower commercialized in Brazil, and the use of gibberellic acid (GA3) to cultivate it in a protected environment may promote the production of high quality flower spikes. This study aimed at evaluating the production of flower spikes and corms of gladiolus ('White Friendship' cultivar) submitted to high concentrations and application methods of gibberellic acid, in a protected environment. The experimental design was randomized blocks, in a 2 x 4 factorial arrangement, being two application methods (foliar spraying and corm soaking) and four concentrations (0 mg L-1, 250 mg L-1, 500 mg L-1 and 1,000 mg L-1) of gibberellic acid, with six replications and two plants per experimental unit. The following traits were evaluated: plant height, number of leaves per plant, marketable harvest point of flower spikes, number of florets per flower spike, flower panicle length, stem and floret diameter, corm perimeter, number of cormels per plant and production of corm fresh matter and leaf dry matter, flower spikes, corms and cormels. High concentrations of GA3 are not recommended for the production of flower spikes and corms of the gladiolus 'White Friendship' cultivar. The corm soaking application method anticipates the harvest of flower spikes and produces a higher number of cormels per plant. Regardless of the application method, the concentration of 550 mg L-1 of GA3 increases the cormel yield of the 'White Friendship' cultivar.

Transition To Flowering

Transition to flowering is described in gibberellic acid (GA) - treated and control plants of Helianthus annuus. Hormonal treatment accelerates reproductive development without reducing the number of leaves developed before flowering. Studies of [3H]thymidine incorporation in the apex show that a non-synthesizing summital group of cells, the central zone, is present in the vegetative as well as the transitional apex. During transition to the floral apex the size of the central zone is gradually diminished, as its peripheral and basal cells undergo synthetic activity and the apex develops a domed shape. In GA-treated shoots the order is changed so that development of a dome precedes activity in the central zone. Cells of the second tunica layer of the central zone are the last to incorporate thymidine. They are conspicuously enlarged and distinct before development of the inflorescence. It is suggested that this layer has a specialized role in flowering.

ABSTRACT The objective of this study was to evaluate the growth of crisp lettuce in hydroponic cultivation, following the nutrient film technique (NFT), using optimized mineral and organomineral nutrient solutions. The experiment was set in 8 x 3 factorial scheme, with treatments distributed in randomized blocks and split plots, with three replicates. The plots corresponded to eight nutrient solutions, of which four were mineral solutions with chemical composition suggested by Bernardes, Furlani, Castellane & Araújo and Ueda, and four were organomineral solutions, suggested by this research with chemical composition similar to those of the previously mentioned mineral solutions. The subplots corresponded to three varieties of crisp lettuce: Thaís, Vanda and Verônica. At 25 days after transplanting, the following parameters were evaluated: stem and crown diameter, root length, leaf area and number of leaves. For stem and crown diameters and number of leaves, the mineral solutions promoted the highest means. The mineral solution of Furlani and the organomineral solutions, except the modified solution of Castellane & Araújo, promoted the greatest root lengths. The smallest leaf area was obtained in the organomineral solution of Ueda. The cultivar Verônica had the highest root length and stem diameter.
