TLDR
In this article, the vessel elements of secondary xylem in branches of columnar and normal apple trees were studied by isolation method and micrographs, and the lengths and diameters were measured and the type of side wall (reticulate or pitted).Abstract:
The vessel elements of secondary xylem in branches of columnar and normal apple trees were studied by isolation method and micrograph. The lengths and diameters were measured and the type of side wall (reticulate or pitted) was noted. Most of the perforation plates were simple. Normal apples had more abnormal vessel element cells than columnar apples. The average diameter of the xylem vessel elements of columnar apples was 43.27 µm, which was significantly greater than that of normal apples (32.64 µm). The lengths of the vessel elements did not differ significantly between columnar and normal apples. The results provided a theoretical basis for explaining the early flowering and fruiting of columnar apple trees and their higher fruit yield.read more

Mapping Co , a gene controlling the columnar phenotype of apple, with molecular markers
TL;DR: Using bulked segregant analysis combined with several DNA molecular marker techniques to screen the F1 progeny of Spur Fuji × Telamon, 9 new DNA markers linked to the Co gene were identified, enabling early selection in progenies where Co is difficult to identify.
Comparison of Leaf Structure and Chloroplast Ultrastructure Between Columnar and Standard Apples
TL;DR: The results showed that the size of palisade tissue cells within the same layer of columnar apple was different and its array was irregular, and there were more wrinkles on the surface of the upper epidermal cells ofColumnar apple and the bulges of epidersmal cells were higher compared with standard apple.
