Ripeness index, fresh weights and humidity of the organs of olive tree growth under irrigation or rain-fed conditions.

Parameter	Irrigation (IR)	Water-Stressed (WS)
Ripeness index	0.50 ± 0.03	0.50 ± 0.02
Fruit weights (g)	2.32 ± 0.13	0.83 ± 0.03 *
Stone weights (g)	0.68 ± 0.03	0.43 ± 0.01 *
Pulp weights (g)	1.64 ± 0.12	0.39 ± 0.03 *
Seed weights (g)	0.05 ± 0.01	0.05 ± 0.01
Humidity of fruits (%)	55.00 ± 3.03	42.42 ± 0.07 *
Humidity of leaves (%)	48.18 ± 0.05	35.05 ± 0.30 *
Humidity of stems (%)	45.56 ± 1.02	37.11 ± 0.04 *
Humidity of roots (%)	42.44 ± 0.89	34.05 ± 1.39 *

The fruit weight was the fresh weight of the whole olive fruit. The stone weight was the fresh weight of the olive fruit without pulp. The pulp weight was obtained as the difference between the fruit weight and stone weight. The seed weight was determined by cutting the stone, extracting the seed and weighing it. Values are means ± standard error of the mean. For comparisons between the irrigation and water stress conditions, values followed by * are significantly different (p < 0.05).
