Why emasculation is done in cotton?
Crop Improvement :: Emasculation. Cotton is an often cross pollinated crop. Pollen is shed directly on the stigma when the anthers open and hence self pollination is the rule. In cotton, the stigma is receptive for 7 hours while the pollen viability is upto 24 hours.
Why is emasculate done in the morning?
Emasculation: Emasculation is done before the anthesis of flower but the stigma has become receptive. Stigma receptivity is at the peak during morning hours. Emasculation is to be done in the evening hours before the anthers are dehisce and stigma is likely to become fully receptive.

How do I stop crossing naturally?
Xanthopoulos & Kechagia (2000) found that out-crossings for 2, 10 and 15 m distance were 2.8%, 0.3% and 0.1%, respectively. Sen and Cicek (2003) reported similar results. Both researches revealed that distances >10 m between cotton plants can effectively prevent natural crossing.
