Micropropagation in wild pear (Pyrus syricca)
Scientia Horticulturae, 1997Abstract Some factors which affect the in vitro propagation of wild pear ( Pyrus syrica ) were studied. Successful shoot proliferation was obtained on Murashige and Skoog medium supplemented with 1.5–2.0 mg 1 −1 benzyl adenine. Shoot height decreased to 1.8–1.6 cm and 1.3 cm with benzyl adenine (1.5–2.0 mg 1 −1 ) and zeatin (1.0–2.0 mg 1 −1 ...

Interspecificity of Scab Fungus Isolated from Wild Syrian Pear (Pyrus syriaca)
Plant Disease, 2023Scab on pear is caused by two pathogens, Venturia pyrina on European pear and V. nashicola on Asian pear. Five races of V. pyrina and seven races of V. nashicola have been reported thus far and pathological specialization occurs in both species. Among them, the five race isolates of V. pyrina were previously found from wild Syrian pear. In this study,

A wild pear native to calcareous soils that has a possible application as a pear rootstock
Journal of Plant Nutrition, 2000Abstract Pyrus amygdaliformis Vill. is native to many if not all soils in Greece, including those which are calcareous. Where it grows in the wild, the CaCO3 content in soils ranges from less than 1 to more than 35%. The pH of the soil ranged from 7.30 to 8.25 for six samples examined.

In vitro shoot regeneration from leaves of wild pear
Plant Cell, Tissue and Organ Culture, 1999Shoot regeneration was obtained from leaves of in vitro cultures of wild pear genotypes. The highest regeneration rates, ranging from 40% to 64%, depending on the genotype, were obtained using leaves wounded by three cuts transversely to the mid-rib, a Quoirin and Lepoivre macro-salt composition, 250 mg l-1 cefotaxime and maintaining the explants in ...
