1 ABSTRACT

 

In this study we examined if the irrigation depths (8, 11 and 14 mm), applied daily, splitted in two frequencies (two and four times a day) affect the seedling quality of Calophyllum brasiliense Cambess. (Guanandi) at nursery and initial development after planting in pot. The 11 mm irrigation depth produces the same amount of seedlings with suitable root systems for planting as the 14 mm irrigation depth and save 21% of water. The 11 mm irrigation depth, splitted in two times a day, compared to 14 mm irrigation depth, produces higher or equal morphological development, which continues after planting.

 

Keywords: Calophyllum brasiliense, irrigation depth, irrigation frequency, forest nurseries

É POSSÍVEL ECONOMIZAR ÁGUA SEM PERDER A QUALIDADE NA PRODUÇÃO DE MUDAS DE GUANANDI?

 

 

2 RESUMO

 

Neste estudo examinamos se as lâminas de irrigação (8, 11 e 14 mm), aplicadas diariamente, divididas em duas frequências (duas e quatro vezes ao dia) afetam a qualidade de mudas de Calophyllum brasiliense Cambess. (Guanandi) no viveiro e o desenvolvimento inicial após o plantio em vaso. A lâmina de irrigação 11 mm produz a mesma quantidade de mudas com sistemas radiculares aptos ao plantio que a lâmina de 14 mm e economiza 21% de água. A lâmina de irrigação 11 mm, dividida em duas vezes ao dia, comparada à lâmina de 14 mm, produz maior ou igual desenvolvimento morfológico, que se mantém após o plantio.

 

Palavras-chave: Calophyllum brasiliense, lâmina de irrigação, frequência de irrigação, viveiros florestais
