Pollen tube study in relation to haploid production in wheat maize crosses
2010
Bhatt, Usha | Khanna, V.K.
In the wide crossing there are many factors that affect the success of fertilization. These include pre as well as post fertilization factors. In wheat x maize crosses similar barriers were also reported. Data were recorded for pollen tube abnormalities and embryo formation frequency for 29 wheat F1's. Pollen tube abnormality was one of the pre fertilization barriers. Pollen tube growth in wrong direction, bursting, swelling, twisting and coiling of pollen tubes was some of the most common abnormalities. A highly negative correlation coefficient was found between pollen tube growth and embryo formation frequency.
