Seed Priming Methods: Application in Field Crops and Future Perspectives

Abstract

To reach in good plant stand, the life cycle of plants is faced with different critical stages such as uneven seed germination, poor and early seedling growth which ultimately results in low crop yield. It is well known that seed priming enhances germination, reduces seedling emergence time, and improves yield and yield contributing characters of plants. Seed priming is a physiological technique of seed hydration and drying to improve the metabolic process prior to germination to fasten the germination, seedling growth, and crop yield under normal, as well as different biotic and abiotic stress conditions. Many researchers have done a lot of research on seed priming in field crops to enhance the final yield. However, different priming methods and their application in field crops are poorly described. Therefore, this review paper discusses seed priming and its different methods and their application in field crops as well as future perspectives of seed priming.

SEED PRIMING AND EXOGENOUS APPLICATION OF SALICYLIC ACID ENHANCE GROWTH AND PRODUCTIVITY OF OKRA (Abelmoschus esculentus L.) BY REGULATING PHOTOSYNTHETIC ATTRIBUTES

“…In this era, different pretreatment application techniques are widely being used on the emergence and establishment of seedlings. Seed priming is one of the most widely used techniques that promote seed germination, enhance morphological parameters, and improve plant growth and development under non-stress as well as in stress conditions (Muhei, 2018;Rhaman et al, 2020Rhaman et al, , 2021a. Therefore, the present study was conducted on the evaluation of the effects of seed priming and exogenous application SA on the okra plant.…”

“…Recently, many studies have been reported that seed priming is a promising technique that enhances seed germination and fastens plant growth under normal and as well as in stress conditions by regulating different physiological processes (Muhei, 2018;Hasanuzzaman & Fotopoulos 2019;Rhaman et al, 2020). Similarly, many reports showed that supplementation of SA enhances the growth and yield of many plant species by regulating photosynthetic attributes (Tahjib-Ul-Arif et al, 2018;Gul et al, 2020).…”

Seed Priming with Phytohormones: An Effective Approach for the Mitigation of Abiotic Stress

“…Different physiological and non-physiological techniques are available for enhancing seed germination as well as alleviating abiotic stresses. Seed priming is a low-cost and effective physiological and biochemical process that stimulates seed germination, enhances morphological parameters, and improves plant growth and development under abiotic stress [ 7 , 8 , 9 , 10 , 11 ].…”

“…Seed priming with hormone solutions is referred to as hormonal priming, and hormonal seed priming plays an important role in seed metabolism [ 9 ]. Currently, hormonal seed priming is a commonly used technique to improve seed germination, seedling growth, and crop yield in adverse conditions [ 19 , 20 , 21 ].…”

Seed Hydropriming Technique in Cereal Crops: A Review

“…Poor soil and high soil temperature will be posed within the alarming climate change in future and seed quality will be a need to be influenced by seed priming (Sivasubramaniam et al, 2011). Hydro priming relies on only soaking of seeds in pure water followed by re-drying to original moisture content prior to sowing making it a low cost and environmentally friendly technique (Rhaman et al, 2020). Uncontrolled water uptake by the seeds during hydro priming is the main limiting factor of hydro priming which results unequal degree of hydration leading to asynchronous metabolic activation within the seeds (Mc Donald, 2000).…”
