“…Boron priming induced an obvious decrease in panicle sterility and consequently improved the number of grains per inflorescence [91]. Binang et al [97] also demonstrated that priming had a significant effect on the number of tillers, number of fertile panicles, and consequently grain yield of new NERICA rice varieties. Promising yield improvement has also been reported for maize [85,98], onion [99], okra [100], and sugar beet [73].…”

Seed priming is a pre-sowing treatment which leads to a physiological state that enables seed to germinate more efficiently. The majority of seed treatments are based on seed imbibition allowing the seeds to go through the first reversible stage of germination but do not allow radical protrusion through the seed coat. Seeds keeping their desiccation tolerance are then dehydrated and can be stored until final sowing. During subsequent germination, primed seeds exhibit a faster and more synchronized germination and young seedlings are often more vigorous and resistant to abiotic stresses than seedlings obtained from unprimed seeds. Priming often involves soaking seed in predetermined amounts of water or limitation of the imbibition time. The imbibition rate could be somehow controlled by osmotic agents such as PEG and referred as osmopriming. Halopriming implies the use of specific salts while "hormopriming" relies on the use of plant growth regulators. Some physical treatments UV, cold or heat,.. also provide germination improvement thus suggesting that priming effects are not necessarily related to seed imbibition. " better understanding of the metabolic events taking place during the priming treatment and the subsequent germination should help to use this simple and cheap technology in a more efficient way.

Hydropriming is one of the presoaking, seed priming technique that allows seeds to imbibe water and go through the first stage of germination but does not allow radicle appearance. After water imbibition, seeds are dried to their original weight. This technique is used to help crops overcome environment stress. This study aims to assess the morphological traits of farmer's seeds for developing priming treatments so as to develop appropriate methods to maximize the effect of hydropriming. We collected farmer's samples of rice sowing seeds grown indifferent regions of Ugandan. For each sample, distribution of the seed density in percentages was calculated. Secondly, germination tests as per seed density levels and as per farmer's seed samples were conducted for deciding appropriate priming treatment. Finally, wooden boxes experiment was conducted to confirm priming effects. As the result, it was observed that the difference in seed density levels affects the quality of farmer's seeds, as observed in the case of NERICA4. If the radicle appears during soaking period, the newly developed radicle dies during the seed drying process in the hydropriming treatment. Seed germination was observed after 24 h of sowing at room temperature, even at a seed density level of 1.17, which is vigorous for germination. Consequently, farmer's seeds were soaked for 24 h to promote water absorption and activate metabolic pathways and to avoid germination failure when seeds are dried to their initial weight. After hydropriming treatment, plant growth was improved. Alternatively, significant difference was not observed in the mean emergence time between hydroprimed and unprimed seeds. These results suggest that priming the seeds by soaking for 24 h and drying to their initial weight considerably affects initial growth after emergence under dry soil condition.

“…Seed priming is one of the techniques to obtain higher yield of rice by producing quality seedlings. Priming is a method that might improve seed performance under the stress conditions such as drought or freshly harvested or aged seeds which might fail to germinate (Binang et al, 2012).…”

The experiment was carried out in the Seed Laboratory of Bangladesh Agricultural Development Corporation (BADC), Gazipur during June to July 2014 to investigate the effects of different priming methods on seed germination and the seedling growth of some rice (Oryza sativa L.) varieties. Four rice varieties: 1) Nerica, 2) BRRI dhan51, 3) BRRI dhan41 and 4) BRRI dhan49; and six priming treatments: 1) On-farm Priming, 2) Hardening, 3) Hydro-priming, 4) Osmo-hardening, 5) Vitamin C Priming and 6) Control were used in the experiment. The experiment was laid out in a completely randomized design (CRD). The treatments were replicated three times. The germination percentage and seedling growth parameters differed significantly among the priming treatments. For germination, Nerica variety showed poor performance, whereas the other varieties were found superior. Among the priming treatments, Vitamin C priming and Osmo-hardening were found superior. In case of interaction, germination was increased with Vitamin C priming and Osmo-hardening in Nerica. For seedling growth parameters, particularly vigor index, shoot and root lengths, BRRI dhan41 and BRRI dhan51 were found superior. The priming treatment Vitamin C and Osmo-hardening performed better than others. Seedling vigor index was increased with Vitamin C priming and Osmo-hardening in Nerica variety. Shoot length at 15th day was influenced by hydro-priming in Nerica. Root length at 10th day was significantly increased with hardening in BRRI dhan41. Vitamin C priming and Osmo-hardening could therefore, be used for improving germination and seedling growth of Nerica. The Agriculturists 2018; 16(1) 34-43
