Germination experiment　light-favoured seed　 light-inhibited seed

experiment content and purpose

Seed does not sprout even though sown (´・ω・`)
Would you like to have that? If germination temperature and watering are appropriate
light-favoured seeds It may be caused by light-inhibited seeds.

 

Effects of light-favoured seeds and light-inhibited seeds

There are two types of species that prefer light to germinate and those that dislike light.

If it is a light-favoured seed, sow the seeds from the top and lightly apply soil

If it is a light-inhibited seed, bury the seeds 1 to 2 cm and then apply soil

It is good with .

But ... is it true? (; ･`д･´)

As such, are there really any differences between the growth of light- and light-sensitive seeds due to light?

I tried an experiment.

 

 

Experimental overview

 

Germination experiment light-favoured seed Effect experiment of light-inhibited seed

 

One of the seeds of the radish of a light tolerant seed
The other is to block the light with aluminum foil and check if there is a difference in growth between each species.

What you have prepared

1. Aluminum foil (for blocking light)
2. radish seeds
3. a container containing kitchen paper. (Place a seed here and observe.)

Emergence experiment light-favoured seeds Effects of light-inhibited seeds

 

In this experiment, we will investigate whether there is a difference in growth between the light application of the light and light-sensitive seeds.

 

First, prepare the radish seeds and put them in a container covered with kitchen paper.

One is for light to come in, the other is wrapped in aluminum foil so that the light will come on.

 

I sprayed water over the lid and left it for 3 days.

 

3 days later

Mum! ! (・ ∀ ・)

It is a great seed of the light-inhibited seed!

The seeds of those who did not hit well had germinated.

 

 

 

 

Experimental results

The seeds of radish of a light tolerant seed do not germinate if exposed to light,

All three seeds germinated in the absence of light.

 

Experimental results from future home garden

light-favoured seeds and light-inhibited seeds were found to grow faster if they were treated according to the lightness of the species(｀・ω・´)

From now on, let's go and see how to sow the species.
