Ziziphus spina-christi, known as the Christ's thorn jujube, is an evergreen tree or plant native to the Levant, East Africa, and Mesopotamia. [3] Fruit and leaves from the tree were used in preparing ancient Egyptian foods, in cultural practices, and in skincare routines - especially with qasil powder derived from the Ziziphus spina-christi tree leaves.
Ziziphus mauritiana, also known as Indian jujube, [2] Indian plum, [2] Chinese date, [2] Chinee apple, [2] ber [2] and dunks [2] is a tropical fruit tree species belonging to the family Rhamnaceae. It is often confused with the closely related Chinese jujube ( Z. jujuba ), but whereas Z. jujuba prefers temperate climates, Z. mauritiana is ...

It is often confused with the closely related Indian jujube, Z ...
Ziziphus / ˈ z ɪ z ɪ f ə s / [3] is a genus of spiny shrubs and small trees in the buckthorn family, Rhamnaceae.It includes 68 species native to tropical and subtropical Africa, Eurasia, and Australia and tropical South America. [1]
PAI may go negative if a tree loses volume due to damage or disease. Periodic annual increment is commonly used instead of current annual increment as a basis for computing growth per cent . Growth per cent indicates the rate of increase with relation to the wood capital required for its production, this is usually based on a single year's growth.
Ziziphus oenopolia, commonly known as the jackal jujube, small-fruited jujube or wild jujube, is a flowering plant with a broad distribution through tropical and subtropical Asia and Australasia. In India, it is mostly found in the deciduous forests of the southern part of the country.
When stocking, a tree's basal area is measured. The basal area is a cross-sectional area of the stump taken about 4.5 feet (1.4 m) above the ground. [7] The equation for calculating the basal area of trees in a stand is Basal Area = 0.005454 DBH 2, where DBH is the diameter of the tree at the aforementioned measuring height. [7]
Agronomic studies often focus on the above-ground part of plant biomass, and consider crop growth rates rather than individual plant growth rates. Nonetheless there is a strong corollary between the two approaches. More specifically, the ULR as discussed above shows up in crop growth analysis as well, as: = . = .
