Resumo
A demanda atual de plantas ornamentais e flores no Brasil ainda é muito baixa quando comparada aos valores consumidos em países do primeiro mundo. Enquanto um brasileiro gasta em média US$ 6,00/ano, um norueguês consome US$ 143,00/ano. O mercado de plantas ornamentais e flores no país vêm crescendo muito nos últimos anos. Para verificar o potencial de uso de recipientes biodegradáveis um experimento foi conduzido na área experimental do Departamento de Recursos Naturais/Ciências Florestais na Fazenda Experimental Lageado da Faculdade de Ciências Agronômicas da UNESP de Botucatu-SP. O experimento teve início em 09/08/04 e término no 22/09/04. Segundo os dados da estação metereológica da UNESP de Botucatu, SP, os meses de agosto e setembro apresentaram em ambiente externo temperatura mínima de 13,18ºC a 17,00ºC; temperatura máxima de 25,01ºC a 29,86ºC; temperatura média de 17,6ºC a 21,84ºC e umidade relativa de 45,38% a 46,53%, respectivamente. Inicialmente o experimento foi conduzido no interior de estufa (A) com controle de umidade relativa, que era coberta com tela de sombreamento de 50%. Para registro da temperatura no interior da estufa (A), foi usado termômetro de máxima e mínima do tipo capela (plástico). A estufa (B) tinha um agrofilme transparente de 150 micra para proteção das mudas, não havendo controle de temperatura e umidade relativa, foram utilizados termômetro de máxima e mínima do tipo capela (plástico) e higrômetro de leitura direta (plástico). Os recipientes usados para formação das mudas foram saquinhos plásticos de polietileno na cor preta (tradicionais) e tubetes biodegradáveis. Os saquinhos plásticos tinham 0,60 micra de espessura, nas dimensões de 10,00 cm de comprimento, 5,00 cm de diâmetro, correspondendo a 196,25 cm3 de volume sendo a parte interna completamente lisa...
The current demand of ornamental plants and flowers in Brazil is still very low when it is compared with the consumed values of development. While one Brazilian spends US$ 6,00 per year, one Norwegian consumes US$ 143,00. The market of ornamental plants and flowers in the country have been growing a lot in recent years. To verify the potencial of biodegradable containers an experiment was lead in the experimental area of the Department of Forest Sciences in Lageado Experimental Farm of the Agronomic Science College of UNESP in Botucatu-SP. The experiment have started in 09/08/04 and ended in 22/09/04. According to the metereológical station of the UNESP of Botucatu, SP, the months of August and September had presented in external environment minimum temperature of 13,18ºC to 17,00ºC; maximum temperature of 25,01ºC to 29,86ºC; average temperature of 17,6ºC to 21,84ºC and relative humidity of 45,38% to 46,53%, respectively. Initially the experiment was lead inner a greenhouse (A), that was covered with screen of shadow of 50%. For register of the temperature in the interior of the greenhouse (A), with 5 control of relative humidity, it was used thermometer of maximum and minimum of the type chapel (plastic) The greenhouse (B) had one agrofilm transparent of 150 micra for protection of the seedlings, not having temperature control and relative humidity, thermometer of maximum and minimum of the type chapel (plastic) and higrômeter of direct reading had been used (plastic).The containers used for the growth of the plants were small black bags of polyethylene (traditional ones) and biodegradable containers. The small black bags had 0,60 micra of thickness, in the dimensions of 10,0 cm of length and 5,0 cm of diameter, with a 196,25 cm3 volume, smooth in the internal wall...
