“…This is characterized by higher seedling growth moisture content, dry matter and pigment accumulation, and high photosynthetic rates. This agreed with the results obtained by Huang (2005) Magnesium, calcium, potassium, zinc, sodium, and iron as well a host of phytochemicals such as resins, flavonoids, carbohydrates, phenols, phlorotannins, glycosides, and alkaloids are an important source of human diets, and their lowconcentration in food can cause serious health problems (Srinivasan, 2006). From this study, it was observed that priming with inorganic salts such as KNO improves the accumulation of 3 these mineral ions and phytochemical constituents of fruits of Abelmoshus esculentus than unprimed.…”

Seed priming is a promising technique that can improve the growth and yield of plants under optimum conditions. The specific priming duration and concentration required for adequate vegetative growth, yield quality, and phytochemical accumulation of Abelmoshus esculentus need clarification. This study was evaluated under screen house conditions, using a completely randomized design (CRD) approach. The seeds of Abelmoshus esculentus were subjected to priming with potassium nitrate for 6 and 12 h duration at a concentration of 0.5 and 1.00 mM while unprimed seeds served as the control. The results revealed that the primed seeds showed improved vegetative growth, yield components, and phytochemical constituents compared to the unprimed control seeds. This observation was irrespective of the priming duration and concentration of potassium nitrate used. Moreover, seeds primed for a 6 h duration at 1 mM were significantly higher in yield, fruit mineral, and phytochemical constituents compared to other treatments. At 12 h priming duration, seeds primed in 0.5 mM of potassium nitrate had higher growth and yield than at 1 mM. Priming with inorganic salts such as KNO3 induces faster growth and maximum crop yield of Abelmoshus esculentus. Priming for a short duration (6 h) 3 and at high concentration is sufficient to enhance the growth process and increased yield of Abelmoshus esculentus and has practical implications in the production of Abelmoshus esculentus .

“…Unlike in the US treatment, watermelon seeds did not respond to water soaking even at the longest duration (60 min). This is probably because this 60-min period was not long enough to overcome the mechanical resistance imposed by the hard thick seed coats of these seeds (Zheng et al, 2007). Extending the duration of water treatment should be tried to see if germination rate could be further enhanced.…”

A laboratory experiment was conducted to determine the effect of ultrasound (US) treatment on seed germination of chickpea, wheat, pepper and watermelon. All tests were carried out at 40 kHz in a water bath ultrasonic device varying two factors, treatment duration (5, 10, 15, 30, 45 or 60 min) and germination temperature (15 or 20 • C). Parallel tests were run in which seeds were soaked in water without sonication in order to eliminate the effect of water from US test results. The effects of US on seed germination varied between crops and were more obvious on germination speed, expressed as germination rate index (GRI), rather than on germination percentage (GP). In particular, US treatment significantly increased the GRI of chickpeas, wheat and watermelon, resulting in a maximum increase of 133% (at 45 min), 95% (30 min) and 45% (5 min), respectively, above control seeds. The beneficial effects of US on the GRI of these crops were observed at both 15 and 20 • C, suggesting that US treatment offers a practical priming method to overcome the slow germination that may occur at low temperatures. Water-soaking treatment improved the GP of both chickpea and pepper seeds by 59 and 24%, respectively, compared to the control but neither water nor US had any positive effect on pepper GRI. Post-treatment measurement of moisture content of these seeds produced variable results depending on crop species and US treatment duration. Results of this research indicated that US treatment effectively enhanced speed of germination of chickpea, wheat and watermelon seeds. This increase in speed of germination may improve early field establishment of these crops in the semiarid Mediterranean region and thus needs further investigation. The US technique may also be very useful for plant propagators in nurseries to achieve fast seedling establishment of watermelon.
