So I grew some radish seeds in a petri-dish using two different biochars. Is it correct to conclude that the seed number 2 is healthier than number 1?
Can anybody help me to understand the growth of fine hairs and root length.
Thank you
If you found similar results for all replications, the answer is yes. however, still at lest you need to take root measurements and the weights of the seedlings etc and then compare the two mediums statistically.
Ghazaleh Chegini - I also agree with Janhvi Pandey that number 2 looks more healthy than no. 1. Not only because of length of root but good development of fine hairs. which showing the biochar material 2 is more porous than biochar material 1. and its more suitable for healthy dispersal of plant root systems.

Am I right in interpreting that you grew two seedlings in the same petri dish with two different treatments (biochar type) ? In which case, how can you tell seedling 2 has healthier roots than Seedling 1, and not interpret it another way ie:
Seedling 2 is actually investing more resources in roots that exploit the better conditions that seedling 1 exists in? or:
Seedling 1 was delayed to some degree by biochar 1, but is not less healthy, just 12/24/36 h behind seedling 2? or:
Seedling 2 had greater seed resources (weighed more) than seedling 1, so was always going to grow faster/bigger/longer roots than seedling 1. This competitive advantage means seedling 1 will lose resources by being grown in the same petri dish.
I appreciate you have simply given us a picture to comment on, but your experimental design may need to be altered if you wish to properly compare the influence of biochar on root growth without the other potentially confounding factors of seed competition.
I think yes, seed No.2 seems healthier than No.1 according to growth parameters in root length and root hair no.
Dear Ghazaleh,
Yes, the seedling 2 has better root parameters. The first question is whether shoot 2 is okay too. The next question is whether you want to decide which of the two biachars is better. The decision must be based on statistical parameters.
Best regards, BS
