Trocas gasosas e produtividade de tomateiro com diferentes hastes por planta
The objective was to evaluate the effect of the number of stems per plant in the gas exchange index, in the productivity and in the harvest precocity of Italian tomatoes. It was used a randomized block design in a factorial scheme 2 x 5, with four replicates. The first factor constituted of two cultivars of Italian tomatoes (“Giuliana” and “Tyna”) and the second by the number of stems per plant. At 78 days, it was evaluated the gas exchanges and production parameters of the cultivars. There was no statistical difference between the cultivars for the gas exchange indexes, however, the cultivar “Giuliana” was more productive. With relation to the conduction types, the highest values of the CO2 liquid assimilation rate were observed for the conduction type 3, however int did not result in meaningful results in productivity. The removal from the main stem retards the crop
期刊介绍:
The Iheringia, Série Botânica is a publication edited by the Museu de Ciências Naturais, Fundação Zoobotânica do Rio Grande do Sul, since 1958. The name Iheringia is actually a tribute to Hermann von Ihering (a German researcher who became a Brazilian citizen) and his important studies in the Natural Sciences.The journal has the mission of publishing articles, reviews and original scientific notes that cover diverse areas in Botany, and may be written in Portuguese, Spanish and English.
The journal is widely available in both international and national scientific community. The issues are published and distributed twice a year to 118 national institutions and 152 international institutions. The distribution is either free of charge or by exchange.
