Arabicum Batang Tunggal

ABT. It means Arabicum Batang Tunggal. From now and future, ABT is the answer for an ideal form of the potential missed a lot of adenium’s grower.

Single Trunk Arabicum (ABT) are mainly high with branches at the top. Secondary branching is not started from the lowest internodes near the caudex, but are typically far above 30cm from the caudex. A naturally high form. Very harmonious with the figure of "a real tree", which features a large high figure. This form is very contradictory to the multi-branches style, which commonly seems on Arabicum style before, widened with much branches around the caudex.

Is a high single trunk arabicum can be considered as ABT? Of course not, because, several types of adenium Arabicum which propagated through cuttings and grafting are also generally have the same form. Arabicum cutting is of course not the ABT, it’s well known as cutting + cultivar’s name, example ; RCN cutting, BG Cutting, etc.

ABT’S CHARACTERISTIC

Root

The main characteristics of the roots of adenium Arabicum is spread and not easy to swell like most Adenium Obesum, somalense and (probably) adenium Swazicum and Boehmianum. With the above characters of the roots mentioned above, ABT will have a large number of roots that do not exceed the caudex size. It’s very different from the roots of another hybrids that are generally exceeds the amount of caudex shape.

Caudex

Caudex growth in ABT is not widely as commonly Arabicum. ABT’s caudex tend to follow the entire volume increases (magnitude) of the tree. This Caudex increasingly faded so that it looks blend with the main stem on the top.

Trunk / stem.
There’s only one stem or trunk on ABT. The length of the trunk is very varied, from about 10cm, 20cm or more. The length of main stem was measured from the distance between caudex with the primary branch (usually split into two or three branches). In the perpendicular form, the main stem are good at ABT pursed up, differences in corm diameter with bottom of a narrow branch. Getting to the top stem diameter smaller.
So far there is no limit on the length of main trunk surely. In development, looked thin at a young age, but according to the development time will be enlarged stem. In order not to look skinny or inclined, the height growth and stem diameter should be compact..

Branches and branching
The definition of branches and branching are stems grew from the main stem that does not approach the main stem caudex. In a perpendicular form, the sprout of general branching outbreaks into two or three at a point adjacent to grow. Branching angle on V (rupture of two) are usually narrower than the three branches broken. Character’s of Arabicum’s stem is stiff and vigorous, the more rigid and lacking in vigor, the better they will be made for ABT.
Comparison between ABT with multibranch arabicum is on the branches. Multibranches Arabicum generally have a lot of primary branching. This model makes the shape of Arabicum caudex grow shorter and wider.
Primary branches are branches that grow from the main stem, in this case could be categorized as growing from caudek. More and more primary branches, making the overall dimensions of trees is also widened. In the form of ABT, the primary branches do not exist, because as a succulent plant, it had been the main stem will turn into like caudex.
Secondary branching is generally referred to as a child branch, is a branch that has a point to grow about 10cm or more above the caudex. This branch also called second-degree branching.Tertiary branch is the branch that has points growing on secondary branch.

Leaves and foliage.
Arabicum leaves and foliage divided into two different types of hairy and shiny types. ABT does not distinguish these kinds. Hairy leaf varieties are commonly have faster in germinate than another (shiny leaves). During the growth of main stems, leaves prevented wherever possible loss is minimized, because the loss cleared till the level of (dormant) will make the trunk look skinny and hard to grow. If this happens and then ABT grow normally, the conical form of the stem upwards it will be difficult to achieve.

Flower

Flower’s shape and color of adenium Arabicum has much in common. Some hobbies prefers dense branching with a dense leaf and foliages, while a few hobbies prefer an easy-flowering varieties. Though pointing at adenium Arabicum, ABT is not a hybrid name. However, in the further development of ABT is very possible to be a part of a cultivar name or hybrid.
