This work aimed to determine the photosynthetically active radiation (PAR) incidence at the berry leveI at east (E) and west (W) direction in a Syrah vineyard growing in a tropical semiarid area of Brazil. During the first semester of 20 IO microclimate measurements were performed in a Syrah vineyard in order to quantify incident PAR on the wall of grapevine rows with northsouth orientation in two treatments of leaf removal and shoot trimming: TI - control (according to farm management) and T2 - no leaf remova I and shoot trimming at 35 days after pruning - DAP (berries lead-shot size stage). The TI treatment was characterized by leaf removal in two different occasions (35 DAP - berries lead-shot size stage and 45 DAP - berries pea-sized stage) and by shoot trimming occurred at 53 DAP (beginning of berry touch stage). The results showed that the ratio between the photosynthetically active radiation and the solar global radiation incident at the top of Syrah vineyard was around 40%. The clusters located on the grape walls facing east are more exposed to the photosynthetically active solar radiation than that ones on grape walls facing west. The practice of leaf removal and shoot trimming lead different values of photosynthetically active solar radiation at the berry. |
