Seed Germination Study in Cardamine

Seed Germination Study started on 6/09/2023 &7/09/2023 by Cubists, Lakshmy from Thrissur kerala,Dr.Nagarjuna from Sikkim & myself from Kozhikode Kerala .

Seed Germination study in Cardamine .
I had collected some cardamine seeds on 31/08/2023 from Homelab Cherukkad, Kozhikode .
I got 25 seeds from a single seed pod .

Inspired by today’s chatshaala session@⁨Shraddha CUBE⁩ @⁨~Smit Lokhande⁩ @⁨shalinisharma⁩ @⁨~gangakr⁩ @⁨Chithra Mam⁩ @⁨Batul Ma’am⁩
I made a set up for seed germination study in Cardamine. I took two bottle lids, washed and sanitized them, and placed a piece of cotton cloth on each lid. The cotton cloth had been washed and ironed beforehand. Then, I added 10 Cardamine seeds to each lid and placed them in a plastic box &Kept near the window . Any suggestions? @⁨Abhijeet CUBE⁩ @⁨Rechel CUBE⁩ @⁨Charvi DSC⁩ &others

Objective: To check the seed dormancy in
Cardamine seeds .
Hypothesis :Cardamine seeds not have any seed dormancy🙃
Expectation :All seeds will germinate within 7-8 days.
Methodology:
Prepare Materials:*
Collected two bottle Caps.
Washed and sanitized the bottle lids.
Obtained two pieces of cotton cloth, which were previously washed and ironed.
Seed Placement:
Placed one piece of cotton cloth on each bottle lid.
Added 10 Cardamine seeds to each cotton-covered lid.
Container Setup:
Arranged the lids with seeds inside a plastic box.
placed the plastic box near a window to provide sun light.
Watering Schedule:
Watered the seeds twice daily.
Morning watering at 10 am.

Lakshmy’ Seed Germination setup; Lakshmy got something interesting :confetti_ball::confetti_ball::confetti_ball::confetti_ball: @04872621705 @lakshmy

Inspired from @⁨Abhijeet CUBE⁩ @⁨Theertha⁩ I have made a setup to find seed germination of cardamine seeds. I have some cardamine seeds that I collected from the month of July. Now it is one month passed it turned to brown in colour. I think the seeds become dormant.
I need to find out does this seeds germinate or not.
Date: 7/9/2023
Time:3pm
Place: Mampilly, Thrissur, Kerala

Objective:
A) To find out the seed germination percentage of brown cardamine seeds.
B) To find out brown seeds have any seed dormancy.

Hypothesis:10% seeds germinate within 1 week of time.

Material needed: Two lids of plastic bottles,
Tissue paper, water, Medicine bottle lid for measuring water.

Methedology:Take two lids of plastic bottle and place layer of tissue paper on it. After add 20 cardamine seeds in it. Then add 20 ml water :sweat_drops: in each of the setups. Lable it as A & B. Then place it near the window.

Previously My cardamine plants facing an issue. There is some signs of infection .

  1. The fruits are drooping
  2. Newly forming fruits are bending
  3. Leaves are curling
  4. New flower buds are not forming.
    Date:4/8/2023
    Place:Mampilly, Thrissur, Kerala

There is some white coloured growth could be able to find out. But cannot exactly find out exactly what is the organism.

Due to the disease I pluck adult plants away. Now in the grow bag new cardamine seedlings are started growing. 6/9/2023, 11:18am, Mampilly, Thrissur, Kerala

Summary

Dr.Nagarjuna’s work
Date :7/09/2023





No signs of germination in them sir… declaring them to be non viable… I’m still having that setup… although I went out of station in between… it was maintained moist… expecting any fungal growth in those setup… In search of new set of Cardamine seeds around… orelse will go with Mustard seeds… if any cubists want to test anything specific about germination, may convey me…

These is what I found in the recording of CUBE National meet 2021. Photo showing different colors of seeds including green ,yellow & brown .

Cardamine with seeds pot having different colored seeds .

Seeds germination experiment by @shalini ma’am & arunima .What I understood is that ,Breaking of Seed dormancy using cold treatment .1)Control : 15 seeds are in two Petriplate ,tap water used .2)15 seeds are in two Petriplate kept in refrigerater for 3 days (4°C) & observed . Result : 100% germination in 8 days .https://www.youtube.com/live/Ybzr3_fYm64?si=mwGz8DoYyEogFn60.

Summary made by @shalinisharma98

1) Lakshmy’s set-up

:sparkles: Design:- She has taken bottle cap and placed layers (4-5) of tissue paper over that cap and then, seeds have been placed over it, where moisture has been maintained in the setup by using water.

:sparkles: Seeds collection was done in starting of July 2023 (before national meet).

:sparkles: Setup was put on 7th Sep 2023.

:sparkles: She has two setup A and B, each with 20 cardamine seeds.

:sparkles: Result:- Seeds of setup A has been germinated 100% in 17 days while seeds of setup B has been germinated 100% in 33 days.

2) Theertha’s set-up

:sparkles: Design:- She has taken bottle cap and placed one layer of cotton cloth over that cap and then, seeds have been placed over it, where moisture has been maintained in the setup by using water.

:sparkles: Seeds were freshly harvested for an experiment.
:sparkles: Setup was put on 6th Sep 2023.

:sparkles: She has two setup A and B, each with 10 cardamine seeds.

:sparkles: Result:- In Setup A, seeds were not germinated till 42 days, so this setup has been kept in refrigerator for 3 days and after that this has been taken out at kept at room temperature. Hence, 100% germination has been seen on 47th day.

While In Setup B, no cold treatment has been given, this has been left at room temperature and 100% germination has been seen on 62nd day.

Summary of seed germination study: Homelab, Cherukkad, Kozhikode

I started seed germination study in cardamine on 6/09/2023.

Collected seed from a single plant in two different days 31/08/2023 & 2/09/2023.

I took two bottle lids, washed and sanitized them, and placed a piece of cotton cloth on each lid. The cotton cloth had been washed and ironed beforehand. Then, I added 10 Cardamine seeds to each lid and placed them in a plastic box &Kept near the window.

Objective: To check the seed dormancy in
Cardamine seeds .

Hypothesis :Cardamine seeds not have any seed dormancy🙃

Expectation :All seeds will germinate within 7-8 days.

Methodology:

Prepare Materials:*

Collected two bottle Caps.
Washed and sanitized the bottle lids.
Obtained two pieces of cotton cloth, which were previously washed and ironed.
Seed Placement:
Placed one piece of cotton cloth on each bottle lid.
Added 10 Cardamine seeds to each cotton-covered lid.

Container Setup:
Arranged the lids with seeds inside a plastic box.
placed the plastic box near a window to provide sun light.
Watering Schedule:
Watered the seeds twice daily.
Morning watering at 10 am.
Evening watering at 5 pm.
(Those days raining in my place, so somedays I watered only once in a day ).

18/10/2023

I followed the protocol in the month of September,later I discontinued watering.(forgot some days)

Date:28/10/2023

Later in 42th day I kept Setup A in refrigerator for three days (43,44,45) and later transferred in the room near to setup B . Parallely on 42 th day onwards I started to watering in Setup B

100% Germination in Setup A
Date :23/10/2023

No Germination in Setup B
Date: 23/10/2023

Setup:A
24/10/2023

Setup:A
100% Germination in setup A in 47th day .

Setup B
0% seed germination in 47 th day .
10% Seed germination in 53th Day
100% Germination in 63th day .

Setup :B

25/10/2023

30/10/2023

1/11/2023

5/11/2023

Conclusion:
Cold water treatment cause 100% Germination in cardamine .
Or cardamine having seed dormancy ranges from 47 to 62 days .

Whiteboard screenshots:



Improvement required: Celebration of Goofups

1)I have used one layered cotton cloth instead of that I can use 2-3 layer .That can hold water for long time & make setup moistened.

Watering can be followed without any delay :neutral_face:

[22/07, 10:57 am] Theertha: Breaking News: Controversy Over Cardamine Seed Germination Resolved

There are many opinions regarding Cardamine seed germination, especially about old versus fresh seeds. When I used old seeds, it took 4-7days to achieve a germination rate of 50% or higher.Repeated for 3times

But when I tried once with fresh seeds, it took 15 days. I have not repeated that experiment.

Initially, I hypothesized that fresh Cardamine seeds will take 15 days to germinate, but this hypothesis was happily falsified.
Instead, I observed seed germination on the 7th day:
*6.6% on the 8th day 33% on the 9th day, and 50% on the 10th day.*:partying_face::partying_face:
[22/07, 11:07 am] Priti CUBE: Note that
The older data was for 80% and 100% germination on 10 th day for new and old seeds respectively

Cardamine germination experiment : 27/6/17
