Influence of the irrigation in the growth Schinus terebinthifolius seedlings
Keywords:
Aroeira vermelha, Water depth, Morphologic featuresAbstract
Aiming to evaluate the development of seedlings of Schinus terebinthifolius under different irrigation depth, an experiment was installed in a greenhouse. The experimental design used was randomized block consisting of 4 treatments with 3 blocks. The irrigation depths evaluated were 8, 10, 12 and 14 mm daily, respectively T1, T2, T3 and T4. Seedling production was performed in tubes with 280 cm ³ filled with pine bark basis substrate and fertilizer. The development of the seedlings, were evaluated by the following characteristics: height of aerial part (APA), diameter at breast height (D),dried mass weight of roots (PMSR), dried mass weight of aerial part (PMSPA), total dried mass (MST) and relation (h/d). The treatment T3 presented the best results in relation to the appraised variables, followed by T2. The Schinus terebenthifolius needs a daily sheet of water of around 10 mm, which is smaller than other pioneer species.
