Broad bean seeds germinate in cotton soaked in a jar. Talking about the characteristics of root and bud growth of broad bean.

Research reason: All kinds of plants can take root, sprout, grow leaves and bear fruits, but what do they develop in the soil? So I did an experiment.

Research methods: observation.

Research process:

Equipment: some broad beans, water, bowls and cotton.

Method: Fill the bowl with water for one day, then put cotton on the bottom of the bowl and broad beans on the cotton, and wait for the next day's observation.

Record:

The next day, the broad beans absorbed enough water one by one, and the seed coat was not as rough as before, but smooth and some had cracks.

On the third day, the cracked one has grown a little root, but the one that didn't crack yesterday also opened the cherry mouth, which shocked me. The seed coat of broad beans is so thick, how did they crack it?

On the fourth day, the roots of broad beans grew a lot. I guess, if we put them on the May Day holiday for a few more days, maybe the sprouts of broad beans will pop up at once!

Research experience:

I go to see my broad beans many times a day. Although sometimes I can't see the change, I believe it must be growing, but I can't see it. I can't help but sigh: life is like this, always growing unconsciously!
