Class Xii Biology Project To Perform Emasculation Bagging And Tagging The pollen should be dusted on the surface of the stigma. cover the pollinated flower immediately with a polythene bag and label it with the name of the seed parent. also read: artifical hybridization. artificial pollination. for any information on biology experiments in cbse class 12, keep visiting byju’s website or download byju’s app for. Comment. i. after emasculation, the flower is covered with small bags to prevent pollination with undesired pollen grains. ii. these bags are made up of polyethene, paper, muslin cloth or parchment paper. iii. the bags are punctured or made perforation so as to provide aeration to the flowers. iv. the flower of male parents are also protected.
To Study Controlled Pollinationвђ Emasculation Tagging And Bagging Procedure to controlled pollination emasculation tagging and bagging: choose a flower bud and open it to extract the stamens. this is referred to as emasculation. it is the female parent vine, so make a note of it. the plant is then wrapped in a plastic bag to keep unwanted pollen from pollinating it. || to study controlled pollination– emasculation, tagging and bagging || class 12 ||#class12 #biology #practical #cbse #spotting this channel helps you to pr. Aim: to perform emasculation, bagging and tagging for controlled pollination principle : conventional plant breeding programmes involve bringing under human control reproductive processes that lead to seed and fruit formation. for this controlled pollination is desirable using male and female parent having desired traits. To perform emasculation, bagging, tagging, re bagging for the study of controlled pollination. materials required: plants with large bisexual flower, scissors, tweezers, brush, polythene bags, paper clips, tags. procedure: emasculation select a flower in bud condition where antheses has not occurred. open the bud carefully and remove the.
