Abstract
In Turkey, P. mahaleb L. is the most commonly used rootstock for sweet cherry.
This study was carried out on some Mahaleb types possessing different degrees of vigor (old and young trees) to determine the relation between vigor and the width and length of the phloem sieve tube elements.
This study was carried out on some Mahaleb types possessing different degrees of vigor (old and young trees) to determine the relation between vigor and the width and length of the phloem sieve tube elements.
The range of variation for the width of sieve tubes was 8.29 ± 0.17 μm for Mahaleb type Kem.4, and 13.96 ± 0.20 μm for Mahaleb seedling Af.5. Variation in length of sieve tubes in old trees of the same Mahaleb types was 128.78 ± 5.45 μm and 182.38 ± 6.29 μm, respectively.
In young trees, width ranged from 11.08 ±0.31 μm for Mahaleb line Kem.18 to 14.37 ± 0.36 μm for Kem.7 and lengths from 144.13 ± 5.41 μm for type Af.2 to 184.29 ± 6.41 μm for Af.10. We found that there was a direct relationship between vigor and the size of sieve tube elements in wood of old trees, but no correlation was found in young trees.
