“…Also, according to these authors, the reduction of chlorophyll in response to environmental stresses depends on the genotype of the plant, and this may have influenced the results of the present study, since three varieties of basil were used. Drought can reduce chlorophyll content in species not tolerant to water deficit (Corrêa et al, 1987).…”

Basil (Ocimum basilicum L.) is a medicinal species used in several areas, such as food, medicines and cosmetics, and the understanding of its physiological behavior under environmental conditions is of paramount importance for the improvement of cultivation methods. The objective of this study was to evaluate the influence of different water availability under physiological, biochemical and metabolic characteristics, in three distinct genotypes: 'Alfavaca basilicão', 'Gennaro de menta' and 'Grecco à palla', during two different phenological stages (vegetative and reproductive). It was found that the water deficit promotes physiological changes to tolerate water stress, and the studied genotypes have different routes to achieve this physiological tolerance, which culminates in a distinct accumulation of metabolites in plants, and can be considered interesting if the final product is the production of essential oils.

“…Resulta da interação de outros fatores, tais como demanda evaporativa da atmosfera, estado hídrico do solo, densidade de plantio, sistema de cultivo e processos fisiológicos (ABRAMS et al, 1992;SILVA, 1999). Processos fisiológicos, tais como crescimento celular e fotossíntese, além da produtividade, são fortemente influenciados pelo potencial hídrico e seus componentes (CORRÊA et al, 1987e SILVA, 1999.…”

A despeito de ser o berço das espécies do gênero Hevea, o Brasil contribuiu, em 2001, com apenas 1,5% da produção mundial de 7,132 milhões de toneladas e consumiu em torno de 3,5% de um total de 7,03 milhões de toneladas da demanda mundial de borracha. Os clones mais produtivos são os orientais RRIM 600, PB 235 e PR 255, com produção em torno de 1. ABSTRACT SAZONAL PRODUCTION AND LATEX CHARACTERISTICS IN RUBBER TREE (HEVEA BRASILIENSIS MUELL. ARG.) CLONES IN LAVRAS, STATE OF MINAS GERAIS, BRAZILIn spite of being the cradle of the species of the genus Hevea, Brazil contributed, in 2001, with only 1.5% of the world production of 7.132 million tons and it consumed around 3.5% of a total of 7.03 million tons of the world demand. The most productive clones are the orientals RRIM 600, PB 235 and PR 255, with production around 1,500 kg of dry rubber/ha/year. The cultivation of those clones in different regions in Brazil shows adaptation to several climatic patterns. The aim of this work was to evaluate the productive behavior of clones of rubber tree, associated to seasonal climatic and physiologic factors in relation to the latex production in Lavras, State of Minas Gerais, Brazil. The research was conducted in the experimental area of Biology Department of Federal University of Lavras, sector of Plant Physiology, between June 2001 and July 2003. The plant water relations and nutritional factors were appropriate to the productive period. The productivity of clone RRIM 600 was higher than the others and presented positive correlation to the environmental factors during the experimental period. The nutritional factors of the latex and the obstruction index showed significant correlation to the production.
