Effects of Copper and Leadon Pollen Germination Traits in Almond Cultivars
There is minimal information about the effect of heavy metals such as lead and copper on pollen grains and pollen tubes of fruit trees. Fruit set of these plants are affected by different environmental, biological, physical and chemical factors. If one of these factors be abnormal, pollination, fertilization and fruit set and orchard yield will decrease. In polluted cities, this phenomenon is a...
متن کاملThe Study of Morphological Traits and Identification of Self-incompatibility Alleles in Almond Cultivars and Genotypes
The evaluation of an almond collection using morphological variables and identification of self-incompatibility genotype is useful for selecting pollinizers and for the design of crossing in almond breeding programs. In this study, important morphological traits and self-incompatibilities in 71 almond cultivars and genotypes were studied. Simple and multiplex specific PCR analyses were used in...
متن کاملMolecular characterization of five new S alleles associated with self- incompatibility in local Spanish almond cultivars
Almond is a highly heterozygous species with a high number of S-alleles controlling its gametophytic self-incompatibility system (GSI). In this work we have analysed Spanish local almond cultivars for S-RNase allele diversity. By cloning and sequencing five new S-RNase alleles were identified: S31 (804 bp) in 'Pou de Felanitx' and 'Totsol', S32 (855 bp) in 'Taiatona', S33 (1165 bp) in 'Pou d'Es...
متن کاملInfuence of pollen source and pollination Time on Furit set of Ferragness Self-incompatibility Almond
Different experiments have showed that interruption in pollination is an important problem in most almond orchards.Asmost of the almond cultivars are self-incompatible,pollination cannot be performed desirably and as a result a failure in almond yield is occurred.Thus under this circumstance,determination of selective cultivars compatibility and choosing appropriate pollinizers are so important...
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 ...
