Show PULI NATION OF CORN COHN contamination NATION OF SILKS BY FOREIGN POLLEN AVOIDED tamel to la covered while still immature an and d before anthers have protruded with ten pound t ol 01 ulu silks from vagrant pollen la is almost alm at certain to occur when the silks have grown to 10 a length of five or six inches within the sack back the ear Is usually in the best condition for pollination since by that time most of tho the silks have grown out the first silks to appear are those from the basal kernels and so BO on progressively outward the tip silks being the last to develop in natural wind pollination of corn the pollen Is blowing about the field for a period of a week or ten days during which time the drifting pollen falls on the successive silks as they appear in artificial pollination it if but a 0 single application of the pollen Is made naturally nati I 1 I 1 11 11 I 1 11 I 1 I 1 I 1 I 1 I 1 I 1 11 I 1 manner of sacking tassel and for pollination only those silks will be pollin abed which happen to be developed and receptive at the time the consequence la Is a nubbin ear for this reason the same ear Is usually gone over by the pollinator two or tareo times in order to secure the successful pollination of the greatest possible number of silks in the method devised by the writer it is believed that a greater number of silks can bo be reached in one pollination and that the danger of contamination from foreign pollen Is practically eliminated the pollen is applied to the silks by means of a common insect powder gun or spring blower the blower to Is filled with anthers and pollen from the sack taken from the tassel the latter being bent over and rapped sharply to secure the shaking off of the loose anthers and pollen in the sack the pollen la Is of course mixed with tho the mass of empty anthers from which it has haa been shed no special care however need bo be taken to get the pollen separated from the anthers but having the nose of the blower cut down to a length of half an inch any anthers which may in ay chance to clog the nozzle c can a n easily bo ba pushed out with a pin As a matter of fact forthe for tho most part tho the blast expels pollen and anthers together without difficulty |
