“…These findings are in agreement with previous reports (Ahmadi et al, 2007;Ghassemi-Golezaniki et al, 2008a). Several researchers reported the positive effect of hydropriming on seedling emergence rate, seedling establishment, early vigor, and the faster development of the seedling (Kibite and Harker, 1991). Priming with PEG-6000 resulted in the highest number of plants per square meter at late sowing in both wheat varieties.…”

This study was conducted to determine the effects of some priming treatments on seed germination properties, grain yield, and several agromorphological characteristics of bread wheat. Two commonly grown bread wheat varieties, namely Adana-99 and Pandas, were selected for experimentation conducted during the 2007-08 and 2008-09 growing periods. The seeds of the Adana-99 and Pandas wheat varieties were primed with the following: (1) distilled water, (2) 100 ppm indole-3-acetic acid (IAA), ( 3) 2.5% potassium chloride (KCl), (4) 1% potassium dihydrogen phosphate (KH 2 PO 4 ), (5) 10% polyethylene glycol (PEG-6000), or (6) gibberellic acid (GA 3 , used only for field experiments). Nonprimed seeds were used as the control group. First 1000 mL of priming media was prepared for each priming treatment, and seeds of both varieties were rinsed in the solution for 12 h at room temperature. Germination percentage at two different temperatures (10 °C and 20 °C), coleoptile length, seedling emergence percentage, and seedling growth rate were evaluated under laboratory conditions. Primed seeds of both varieties were sown on two different dates under field conditions to evaluate certain agromorphological characteristics. PEG, IAA, and distilled water treatments increased seed germination percentage, seedling emergence percentage, and seedling growth rate. PEG, KCl, and hydropriming treatments increased grain yield compared to the control. Among the different priming agents used in the study, PEG, KCl, and hydropriming were the most effective treatments to attain higher germination percentage and grain yield.

“…Good germination and emergence are the key to controlling stand establishment. Kibite and Harker (1991) reported that seed hydration of wheat, barley and oats seeds improved the uniformity of seedling emergence. Harris et al (1999) found that hydropriming enhanced seedling establishment and early vigor of upland rice, maize and chickpea, resulting in faster development, earlier flowering and maturity and higher yields.…”

Early emergence and stand establishment of cowpea are considered to be the most important yield-contributing factors in rainfed areas. Laboratory tests and afield experiment were conducted in RCB design in 2011 at a research farm in Ramhormoz, Iran, to evaluate the effects of hydropriming (8, 12 and 16 hours duration) and halo priming (solutions of 1.5% KNO 3 and 0.8% NaCl) on seedling vigor and field establishment of cowpea. Analysis of variance of laboratory data showed that hydropriming significantly improved germination rate, seed vigor index, and seedling dry weights. However, germination percentage for seeds primed with KNO 3 and non-primed seeds were statistically similar, but higher than those for NaCl priming. Overall, hydropriming treatment was comparatively superior in the laboratory tests. Invigoration of cowpea seeds by hydropriming and NaCl priming resulted in higher seedling emergence and establishment in the field, compared to control and seed priming with KNO 3 . Seedling emergence rate was also enhanced by priming seeds with water, suggesting that hydropriming is a simple, low cost and environmentally friendly technique for improving seed and seedling vigor of cowpea.

Good germination of rice is considered critical for the plant life cycle. A laboratory experiment was conducted in IAAS, Lamjung campus, Sundarbazar to study the effect of different priming methods in rice. The experiment was done in completely randomized design using 12 treatments replicated thrice. The treatments consisted; Control (No priming), Hydro priming (soaking of seeds in distilled water for 72 hrs), PEG6000 - 5% and 10%, CaCl2 – 0.5% and 1%, KCl – 2% and 4%, KNO3 – 1% and 2% and NaCl – 1.8% and 3.6% where seeds were soaked for 12 hours followed by 12 hours drying. Both hydro priming and PEG improved germination energy, germination index, germination speed, radical length, and plumule length. The effect due to varied doses were not observed in the priming substances except PEG 6000, where PEG6000 – 5% was better as compared to PEG – 10% in overall observations.
