The present work was conducted to find out the role of seed priming on wheat germination. The study was carried out in the Central Laboratory of Centre for plant Sciences & Biodiversity (CPS&B), University of Swat, Pakistan. Three wheat genotypes (HU-12, HU-17, and HU-20) and two check cultivars (Inqilab-91 and Chakwal-50) were studied. Seven priming media were employed which included Urea 1% and 0.5%; Distilled water (dH2O), diammonium phosphate (DAP) 0.5% and 1%; single super phosphate (SSP) 1% and 0.5% with priming duration 18 and 36 h. The priming media (PM), genotypes (gen) and priming duration (PD) significantly affected germination percentage, germination rate index, root diameter, root length and shoot length. Seeds primed with dH2O for 18 h performed well for all the studied attributes followed by Urea 0.5%, Urea 1% and DAP 0.5%. Similarly, the wheat genotypes HU-20 and HU-12 performed well for all the studied attributes followed by HU-17, Inqilab-91 and Chakwal-50 respectively. Further, PD of 18 h was observed to be more appropriate when compared to 36 h priming duration. The genotype HU12, HU17 and Inq91 performed better regarding root fresh weight in both controlled and stress conditions. The genotype HU12, HU17 and HU20 performed well for chlorophyll a, chlorophyll b, total chlorophyll and proline content in both controlled and stress conditions when compared to check cultivars. Further, a less relative decrease in chlorophyll content and an increase in proline content indicated that priming with urea 0.5% for 18 h duration has enhanced the osmotic tolerance of the studied wheat genotypes.

Seed Technologies to Help Reduce Risks and Improve Carrot Crop Performance

Every season you plant a crop, there are risks. Weather, poor germination, insects, disease, and nutrient deficiencies are just a few of the risks that may run through your mind before you plant your next carrot crop. To reduce your risks, why not consider utilizing seed technologies that help improve your crop performance starting with your seed? The following are a three seed technology…

More Seed Priming Tips: Spinach

Seed priming has changed how I plant many of my garden seeds. Seeds are precious and expensive so taking steps to improve germination makes sense. It also gets our garden plants growing faster. Be sure to read a previous blog post on seed priming which gives techniques for 12 different vegetables.

Seed Priming Tips for Vegetable Gardeners

The same website, GrowVeg.com, provided instructions for seed priming of spinach seeds. They’re finicky for me when I direct sow them. Though spinach seeds will germinate at soil temperatures as low as 35 degrees F, the optimal temperature range for germination is 65-75 degrees F. During the winter months here in USDA Zone 10b, the soil temperature typically does not reach those temperatures.

Spinach seeds do germinate when I direct sow, but germination percentage is suboptimal and slow. Sometimes I grow starts in a sunny kitchen window. So here are the instructions from Growing Spinach in Spring for seed priming spinach seeds.

To improve my germination luck, I prime spinach seeds a few days before planting them. This process involves soaking the seeds in room temperature water overnight, then letting them dry at room temperature for a day or two. When spinach seeds are primed in this way, the first stage of germination takes place under warm, clean conditions, so the seeds are much faster to sprout after they are planted in the garden.

I followed the same instructions for radish seeds, since their optimal germination temperature range is 65-85 degrees F. I planted the spinach and the radish seeds on April 12 and six days later they had germinated and poked through the soil. Today, before the sun warmed the soil the temperature was 60 degrees F. at 1-3 inches—still below the optimal range.

Conclusions: 1. Seed priming spinach seeds hastened germination from a typical 6-14 days at optimal soil temperatures to 6 days at suboptimal temperatures. 2. Seed priming radish seeds may not have speeded germination significantly since typical days to germination at optimal temperatures are 4-10 days. I probably won’t prime them again but just plant a few more than I usually do.

Looking forward to this.

Thinning Beets

Beet micro-greens—really just the yield from thinning my beets. Unless you plant mono-germ beets, each seedball/fruit will produce two to four seedlings, which of course won’t work.

Germination was better than usual this year for the six rows of twenty beet seeds each. I used a recommended seed priming technique that might explain the approximately 85% germination. There were a few still popping through the soil today. Here are the steps from Grow Veg:

Beet seeds have thick, wrinkled seed coats that soften when “washed” in several changes of water. Place seeds in a jar, cover them with room temperature water, and drain off and replace the water every 30 minutes. After six changes of water, many of the natural germination inhibitors present in the seed coats are removed. Drain the primed beet seeds on paper towels overnight, and plant the next day. Primed beet seeds emerge in 4 to 5 days, compared to 7 to 12 days for dry seeds.

Thinning beets can be tedious but sharp scIssors help. I select the sturdiest in the seed clump and snip the others with scissors. Sitting on a little garden bench, I snipped away and now have some micro-greens for a salad.

And this is what I’ll be waiting for.

Seed Priming Tips for Vegetable Gardeners

I came across this post on seed priming written by my favorite garden writer, Barbara Pleasant and knew I would share it with readers. You can find the GrowVeg link below.

We all want our seeds to germinate promptly and successfully. Purchased seeds are expensive and we don’t want to replant when there are failures. We lose days of the growing season and frankly, it’s disheartening, especially for beginning gardeners.

These are some of the seeds that Barbara Pleasant provides instructions for seed priming.

Seed Priming Tips for Vegetable Gardeners

I had been a vegetable gardener for years when I discovered the difference seed priming can make with vegetable seeds that are slow or erratic sprouters. In my first try, I watched with amazement as parsnip seedlings from primed seeds popped up like little soldiers. A different technique resulted in beet seeds that emerged with the speed of radishes, while a third method gave me spinach seedlings less than a week after planting. Everyone should know these tricks! Read more

After all, isn’t this the goal?
