Comportamento do potencial de água na folha em tangerina murcote submetidas a diferentes lâminas de irrigação.

Abstract

“Murcot”tangerine was irrigated in a statistical design of four spray irrigated treatments and one not irrigated control. It was evaluated the plant behaviour with respect to leaf water potential at non, from August to November, during the years of 1994 and 1995. The treatment with 100% of pan evaporation water depth control and treatment with no irrigation, were evaluated with respect to all day long leaf water potential during the months of May, July, September and October of 1995. It was verified leaf potential values during 1995 greater than those in 1994, and the values decrease from sunrise to noon, with tendence for increasing after noon.
