Pollen Tube Growth and Self-Compatibility in Almond.
Although pollen tube growth has been an important criterion for self-compatibility evaluation in almond, there is not a clear-cut separation between positive and negative growth of pollen tubes in the different genotypes. The examination of pollen tube growth after selfing almond seedlings has allowed establishing different levels of compatibility, but not a clear-cut separation between self-co...
متن کاملpollen tube growth track and determination of compatibility in almond
almond is one of the most important species of genus prunus. most almond cultivars and genotypes are self-incompatible and some of others are cross-incompatible. in this study compatibility and frequency pollen tube penetrate in the ovary were performed in three groups. the first group included the genotype a9.7 as female parent and tuono with genotypes a230, a10.11, a8.39 as male parents, the ...
متن کاملSelf-incompatibility in the Iranian Almond Cultivar ‘Mamaei’ Using Pollen Tube Growth, Fruit Set and PCR Technique
Self-incompatibility has been studied by using controlled pollination, pollen tube growth and PCR methods in the Iranian almond ‘Mamaei.’. Pollen tube growth and fruit set following self and cross-pollination treatments were evaluated. The percentage of initial and final fruit set was determined for each treatment at 30 and 60 days after controlled pollination. Pollen germination and pollen ...
متن کاملIons and Pollen Tube Growth
Ions play a crucial role in the control of pollen tube growth. In this review we focus on four that seem especially important: calcium (Ca2+), protons (H+), potassium (K+), and chloride (Cl–). Ca2+ in the extracellular medium is essential for growth; it forms a steep intracellular tip-focused gradient, and exhibits a prominent extracellular tip-directed Ca2+ influx. pH is also essential for gro...
