How can you assure that all or each and every seed you use are all alive and not dormant or dead?

Question

I conducted an investigatory project concerning the growth of pechay (Wild Cabbage) and mung bean. I planted them on three different soil types (loam, clay, and sand). Some grew but some didn't. How do I know that they didn't grow because the soil does not support it and not just because it was dead/dormant in the first place?

Answer 1

You are very unlikely to get 100% germination. What you do with the seeds is sprout them in ideal conditions to find the germination rate.

However in your experiment it doesn't really matter. You are comparing the three soil types. As long as you planted enough to make a decent sample the comparison should be valid. So if you only planted two or three that won't be enough. 10 or 20 and the results will be more valid.

Answer 2

First test your germination rate. Take 100 seeds wrap them in 7 or so layers of paper towel and rubber band it together then fill a large glass 1/2 full of water set the paper towels upright and set in a room temperature DARK place wait 5 to 7 days checking the watter level daily unwrap and count how many sprouted if 75 sprout you know that 3/4 of your crop will at leased germinate

Answer 3

Start the seeds layered between wet paper towels placed in a open sandwich bag. When the seeds germinate, transplant them into the soils. I would plant at least 3 per soil type. That way, if one seedling is damaged you will be able to see this when others still grow.

Answer 4

A dormant seed is alive,as evidenced by skill of the undeniable fact that it keeps to respire, albeit at a a lot decrease fee than regularly. Dormancy comes from the Latin be conscious which skill "to sleep". that's a topic of extremely low metabolic fee and suspension of advance and progression. situations required to interrupt dormancy selection between plant species. some seeds germinate as quickly as they're in a suitable environment. Others stay dormant till a particular environmental cue motives them to interrupt dormancy.
