USO RACIONAL DE NUTRIENTES NO CULTIVO HIDROPÔNICO DE AMOR-PERFEITO  Milena Andrea Curitiba Pilla1; Lenita Lima Haber1; Hélio Grassi Filho2.1Departamento de Produção Vegetal – Horticultura, Faculdade de Ciencias Agronomicas, Universidade Estadual Paulista, Botucatu, SP, [email protected];  2Departamento de Recursos Naturais - Ciência do Solo, Faculdade de Ciencias Agronomicas, Universidade Estadual Paulista, Botucatu, SP  1 RESUMO O objetivo deste trabalho foi avaliar diferentes concentrações de solução nutritiva no cultivo hidropônico de Viola x wittrockiana Gams. O experimento foi conduzido em sistema hidropônico DFT, no delineamento experimental inteiramente casualizado, em esquema fatorial 5x4, com cinco concentrações de solução nutritiva (50, 75, 100, 125 e 150%) e quatro épocas de avaliação, contando cada tratamento, de três repetições de três plantas. Foram analisadas a altura de plantas, o comprimento da raiz, o número de folhas, as flores e botões florais e a massa fresca e seca da parte aérea e da raiz. Os resultados obtidos foram submetidos à análise de variância, teste de Tukey para épocas de avaliação e análise de regressão para concentrações da solução nutritiva. Foi observado um decréscimo no desenvolvimento da parte aérea e do sistema radicular com o aumento do número de dias de cultivo e, o maior número de botões florais ocorreu na terceira semana de cultivo. Observou-se, de maneira geral, uma redução na altura de plantas, no comprimento do sistema radicular, no número de folhas e na massa fresca e seca da parte aérea com o aumento da concentração de nutrientes na solução nutritiva. UNITERMOS: Viola x wittrockiana Gams, solução nutritiva, concentração salina.  PILLA, M.

RATIONAL NUTRIENT USE IN HYDROPONIC CULTIVATION OF “Viola x wittrockiana Gams”  2 ABSTRACT The objective of this work was to evaluate different concentrations of nutritional solution in the hydroponic cultivation of Viola x wittrockiana Gams. The experiment was conducted in DFT hydroponic system, in a completely randomized design with a 5x4 factorial scheme and five nutrient solution concentrations (50, 75, 100, 125 and 150%), four evaluation periods with three replications of three plants for each treatment. Plant height, root length, number of leaves, flowers and floral buttons; fresh and dry weight of shoot and root were determined. The results were submitted to variance analysis, Tukey’s test for evaluation periods and regression analysis for nutrient solution. A decrease in the development of the shoot and root was observed with an increase of the number of cultivation days; the greatest number of floral buttons occurred in the third week of cultivation. A reduction in the plant height, root system length, the number of leaves and the fresh and dry weight of shoot was observed generally with the increase of nutrient solution concentration. KEYWORDS: Viola x wittrockiana Gams, nutrient solution, saline concentration.

The purpose of the studies was to determine the effects of media containing composts from sewage sludge and potato pulp on the flowering and decorative value of 'Butterfly Yellow with Blotch' parviflorous pansy. In the experiment 14 potting media, including 12 media made of 4 composts, were tested. The percentage of compost mixed with sphagnum peat was 25%, 50% and 75%. The components of particular composts were as follows: I - municipal sewage sludge 70% and straw 30%; II - municipal sewage sludge 70% and sawdust 30%; III - municipal sewage sludge 35%, potato pulp 35% and straw 30%; IV - municipal sewage sludge 35%, potato pulp 35% and sawdust 30%. Two control potting media were used: 1 - sphagnum peat with Osmocote Exact Lo-Start at the dose 5 g×dm<sup>-3</sup> and 2 - sphagnum peat with Azofoska at the dose 2.5 g×dm<sup>-3</sup>. There was no top-dressing during cultivation. The pansies for whose cultivation a slow-release fertiliser was used turned out to have most flowers, but the plants cultivated in compost with peat at the ratio 1:1 had equally abundant flowering. At the generative stage, the pansies in control media were the most decorative and those growing in 25% of compost I, 75% of compost II and 50% of compost III and IV. On the basis of plant valuation scale, quality assessment and the abundance of flowering it was found that the media containing 50% of composts were optimal for pansy cultivation.

Triploid banana cultivar is the most desirable cultivar in banana industry because of its higher yield compared to its diploid cultivar.  The  triploid cultivar can be produced by crossing tetraploid with diploid cultivar.  However, tetraploid banana cultivar is rarely existed naturally.  Induced tetraploid of Pisang Rejang was produced using oryzalin. The present research was conducted to characterize tetraploid Pisang Rejang (Musa acuminata, AAAA genome) induced by in-vitro oryzalin treatment from diploid Pisang Rejang. Ploidy level, molecular and morphotaxonomic characters were observed.  Ploidy identification of induced Pisang Rejang was conducted using Flowcytometer.  Molecular characterization was done using RAPD and ISSR markers. Morphology characters were observed based on UPOV (2010). The results showed that tetraploid plants have similar genetic properties with their diploid controls as shown by genetic identity of 0.9901 – 0.9935. The tetraploids were differed from their diploid plants in plan habit and diameter of fruit.  The tetraploid plants produce fewer suckers, drooping leaves and broader fruits compared to its diploid control.

The purpose of this paper is to determinate the influence of salinity on the growth and development of pansies (Viola x wittrockiana Gams.). The objective of the present study was to examine the cultivation area selection and use of pansies related to the autumn and winter flowering aspects. A total of 40 pansy seedlings were included in the study and allocated to four groups of ten each. The experiment conducted four involved treatments: control (K), treatment with 3g/l NaCl (T1), treatment with 5g/l NaCl (T2), and treatment with 7 g/l NaCl (T3). Concentrated water was used for watering the seedlings observed during growth. Over the course of the eight-week experiment, the following quantitative and qualitative properties of the pansy seedlings were measured: height, number of leaves, number of flowers, diameter of flowers, length of leaves, width of leaves, as well as the vitality and decorativeness of the pansy seedlings. The results obtained show that pansies can tolerate increased amounts of salt (5 g/l and 7 g/l NaCl) with adverse effects on the growth, development, vitality and decorativeness of the plant.

This research was carried out to analyse the effect of diverse types of fertilisers on the morphological features of pansy seedlings (Viola x wittrockiana Gams.), as well as to decide on the most appropriate concentration of fertiliser in order to obtain the highest seedlings quality. Two different types of liquid fertilisers were used in this experiment - Magnicvet and Magnihortal with six treatments. Each treatment comprised 30 plants or a total of 180 plants in the experiment were used. 30 plants per treatment were measured, 50 days after planting into plastic containers. The following biometric parameters were analysed: plant height (mm), stem thickness (mm), number of branches and number of flower buds. Measurements of biometric parameters showed that the liquid mineral fertiliser Magnihortal with NPK 10-5-5 + micro elements is more appropriate as compared with the liquid mineral fertiliser Magnicvet with NPK 7-1-5 + micro elements concerning the reinforced nutrition and eventually the enhanced quality of Viola x wittrockiana Gams. seedlings. Treatment V (Magnihortal 0.3 %) showed the highest average height of seedlings, average stem thickness and average number of branches, while the treatment VI (Magnihortal 0.4 %) showed the highest average number of flower buds.
