There are reports that seed priming helps in improving the yield and quality of various crops significantly. However, many of researchers do not agree with this. Kindly share your experience in this regard.
Dear Dr Dr FAROOQ Khan
In unfavorable conditions, seed priming that enhances rooting can create a better seedling establishment and improve the vegetative growth and yield. However, under favorable growth conditions, seed priming probably is not significant. Based on my experiences, seed priming is affected by the number of irrigation, water temperature and leaching.
Priming is believed to be an effective technique that increases germination, plant growth and improve yield of several vegetables and crops . Primed seeds have great potential to grow under stressful conditions. It has strong resistance against disease and insect attack by applying the coating of fungicides, bactericides and nematicides . Primed seeds have much growth potential and give more production as compared to non-primed seeds. It showed that more yield and uniformity as compare to non-primed seeds....
@Farooq, I think under stress condition seed priming is very useful for suitable metabolic reactions in seeds which improve seed germination growth and yield. But under normal situation, it may enhance the carbohydrate, lipid or amino acid metabolism as claimed but the effect is not always significant.
Dear Dr FAROOQ Khan
Seed priming is a controlled hydration technique in which seeds are soaked in water or low osmotic potential solution to a point where germination related metabolic activities begin in the seeds but radical emergence does not occur.
It is off course an effective method of increasing yield indirectly as it improves germination..The benefits of seed priming are enlisted below-
1) It decreases the time to germination.
2)Increase the rate of germination.
3)Crops can compete more effectively with weeds.
4)Eliminate or greatly reduce the amount of seed-borne fungi.
5)Emerges from the soil at most faster rate and uniformly.
6) Improves seed performance at stress conditions.
So, It can be easily concluded that this method is very effective for enhancing yield indirectly through the above mentioned points.
Sir, there are several factors driving the success of the priming. May it be the content of the solutions or the retention of the primers. It will give good result, if all the factors are optimized properly before applying to a broad scale, as the results deviate from one genotype to other and obviously there are non human influences too.
