| description | In Bolivia, potato planting is done twice a year, the spring planting being the most important. This planting is made from October through November in non-irrigated lands in the highlands and bigh valleys, and the second planting of early potatoes is made from April to September in irrigated valleys Since potato seed degenerate rapidly in the valiers as the result of virus diseases, the seed for these plantings comes from higher elevations and the high plains. However, potatoes for the early plantings baivested in the higher elevations are still dormant, and these seed potatoes upon planting remain in the ground a long time and the germination is very irregular To overcome this difficulty, a study has been made to see if it is possible to break the dormancy of seed potatoes with ethylene chlorobydvin, and the combined action of beat from the sun, temperature and bumidity.
The use of ethylene chlorohydrin as a gas, inmersing the potatoes, and mo-istening the seed with water solutions of 6 and 10 percent, induced early pronting of Andean potatoes. Inmersion and moistening were most effective
Exposme of potatoes to sunshine for a period of three weeks induced early spronting, compared to the check stored at 12-15 degrees C. and 55 percent bumidity which are the conditions under which potatoes are stored in Cochabaniba
When potatoes exposed to sunshine for one, two and three weeks were tored in a basement at 14-15 C. and 98 percent bumidity, all spronted at the same time as the checks stored under the same conditions since the start of the experiment. This may indicate that the humidity is an important factor in breaking dormancy. since the lots of potatoes with different periods of sunshine as compared with the check, did not show any differences. |
