The main difference is that the subjects are categorized differently, the morphological characteristics are different, the growth habit is different, specific as follows:
One, the subjects are categorized differently
1, olive
Olea europaea, is twisted flower order, mignonette, mignonette, mignonette species plants.
2, olive
Olive, is the Sapindaceae, olive family, olive genus, olive species plants.
Two, different morphological characteristics
1, olive
Evergreen small trees, up to 10 meters high; bark gray. Branches gray or gray-brown, nearly cylindrical, scattered round lenticels, branchlets angular, densely covered with silver-gray scales, slightly compressed at the nodes. Leaf blade leathery, lanceolate, sometimes oblong-elliptic or ovate, panicles axillary or terminal, ovary globose, glabrous, style short. Fruit ellipsoid, 1.6-2.5 cm long, 1-2 cm in diameter, blue-black at maturity. Flowering April-May, fruiting June-September.
2. Olive
Tree, 10-25(-35) m tall, with stipules, present only at bud time, attached to branches near the base of the petiole. Leaflets 3-6 pairs, papery to leathery, lanceolate or elliptic (to ovate), glabrous or with scattered bristles on abaxial nerves, abaxial surface very finely warty; apex acuminate to cuspidate-acuminate. Inflorescences axillary, slightly tomentose to glabrous; male inflorescences thyrses, many-flowered, fruit ovoid to fusiform, suborbicular in cross-section, yellowish-green at maturity; exocarp thick, wrinkled when dry; pyrenes acuminate, rounded to hexagonal in cross-section, flowering in Apr-May, fruit ripening Oct-Dec.
Three, different growth habits
1, olive oil
Olive oil on its growth of the soil has no special requirements, as long as the PH value of 6.5-8.0 between, the soil is loose and permeable, either in siliceous soil or in calcareous soil can grow. However, studies have shown that the best olive oil comes from the fruit of the olive tree in calcium-rich, fertile soils.
2, olive
The soil adaptability is wider, river banks, hills and mountains, red and yellow loam, gravelly soil can be cultivated, as long as the soil layer is deep and well-drained can grow well.
