Turgor pressure (pp) is a component of total water potential (pw) associated with cellular expansion and plant structural maintenance. In this paper, leaf and fruit pp of passion fruit were monitored using the Wiltmeter® and Turgormeter, respectively. Results are discussed considering environmental variations in savannas of Piauí, Brazil. A completely randomized factorial design was used with three measurement times a day (6, 13 and 16 h), in 3 periods of the year (mean relative humidity varying from 33 to 84%) and 18 replicates. Fruit pp was evaluated on the day of harvest and during post-harvest period (6, 12 and 18 days after harvest). The measurements in different times of the year affected the leaf pp. The lowest pp values were observed when relative air humidity (RH) dropped to 33% (high vapor pressure deficit). Higher leaf pp values were found at 6 h and when RH was 66%. The highest fruit pp values occurred on the day of harvest, with a reduction of 74% associated with a decrease of 23% in fruit weight after 18 days. The Wiltmeter® and Turgormeter are efficient at measuring and monitoring leaf/fruit turgor pressure and could be valuable alternative for post-harvest and plant water relation studies. |
