Observation diary about seed germination Part 1

After lunch, my mother said to me with a smile: "Yaya, do you want to see how seeds germinate?" "I want to." !" I said excitedly. Then, my mother went to the kitchen to get some soybeans and black beans, took them to the balcony, put them in a box, poured some water in the small box, and placed them in the corner of the balcony. Mom said, "Yaya, let's see it tomorrow." Let’s do it.”

The next morning, I got up from bed early. I ran to the balcony and saw that the soybeans and black beans were no longer as wrinkled as they were yesterday, but were bulging, like little fat ones, with a bit of fragrance. After observing, I changed the water for the soybeans and black beans and put them back in their original places.

After lunch on the third day, my mother said: "Come and see, there are new changes!" I heard it and ran over in a hurry, ah! Some beans have sprouted. My mother said: "Yaya, let's get some beans and plant them!" I happily planted beans with my mother. My mother said: "When planting, the buds have to be upward to grow." Then she inserted the beans into the soil of the flower pot.

Today is already the fourth day. After lunch, I went to the balcony to look at the sprouts. Today's bean sprouts are so beautiful, some look like little mice with a big tail; some look like little tadpoles; and some are still naked "little fat guys". So cute!

It was sunny on Sunday, November 12th

At noon today, I found that the soybeans had grown small leaves, a pair of fluffy leaves , like a small cattail fan, standing out from the cotyledons. The cotyledons seemed to have shrunk and shriveled a lot. I later learned that the cotyledons shrunk and shriveled because the leaves had grown out. The cotyledons need to provide nutrients to the leaves so that the small leaves can grow smoothly. grow. I was very happy when I saw the soybeans growing leaves. I quickly took out a ruler and measured it, what a boy! It used to be only 1 centimeter, but now it is almost 16 centimeters. I stroked it gently and thought: Soybean, soybean, grow up quickly. I will watch you and accompany you to grow up.

After a few days of observation and checking a lot of information about seeds through the computer, I learned that when a seed germinates, the radicle first emerges from the cotyledons, grows into a rhizome, then the cotyledons open, and then grows out. Xiaoya’s. The cotyledons of some seeds do not store much nutrients. After being unearthed, photosynthesis is required to produce nutrients for the initial growth of the plant.

It was sunny on Wednesday, July 6th

As soon as school was over, I soaked a few mung beans given to me by the teacher in water. When I was young, the mung beans were already full of water, and they were round and full, as if they were about to burst. However, some mung beans were small, like malnourished children. I found a paper cup, poked a few holes with a toothpick, put a soaked napkin on it, and then covered the mouth of the cup with the towel so that Beanie Babies could breathe fresh air.

The sky was sunny on Friday, July 8th

I couldn’t wait to see the mung beans early this morning. Some have sprouted about 2 centimeters of buds; some have taken off their green coats, revealing their white and smooth bodies; some have just cracked a small slit! They are all eager to go to the outside world to see how beautiful it is!

The sky was cloudy on July 10th.

Today I went to see mung beans again. I saw the mung beans scrambling to grow upwards. Some of them were already very big, about 10 centimeters long, like weightlifters. They all lifted up the gauze. They were really called Hercules. Some of them grew two pieces. The young leaves are like a pair of small scissors, and some green sprouts are entangled with each other, as if a pair of close friends are talking quietly! There are also a few green sprouts that are the shortest. They lower their heads, as if they are afraid that their companions will laugh at them. How interesting!

Through this observation, I gained a lot of knowledge and experienced the joy of life. Observation diary about seed germination Part 4

Sunny day of X month X, 20xx

This morning, I found that the soybean seeds had grown small roots. That was what the teacher did for us. When the teacher gave it to us, it was still a small soybean with a diameter of less than 1 cm. It was flat. Now it has grown very short roots and almost invisible fibrous roots.

There are a few soybeans that have taken off their outer "clothes", and a few soybeans that are taking off their "clothes". The soybean seeds that have taken off their clothes are like a small green balloon. The root of the seed is segmented one by one, and there are several small protruding edges on the edge of the root, which are its fibrous roots; its cotyledons are like a flat feather pat, green and with some luster, whether it is It's extremely peaceful when viewed up close or from a distance. The germination period of soybeans may surprise you. Generally, it takes 1-2 weeks for seeds to germinate, but for soybean seeds, as long as they are in a suitable growing environment, it can take as long as 4-5 days or as short as only 1-2 days.

I put soybean seeds in the living room, which not only facilitates my observation, but also adds a little green to the home. No wonder our whole family loves it! Observation diary about seed germination Part 5

Today, the 120 seeds I originally planted sprouted. At that time, I used 60 soybean seeds and 60 mung bean seeds.

I first used two pots, one for soybeans and one for mung beans. I put a little soil in the pot where I was going to plant soybeans, pressed the 60 soybean seeds on top of the soil one by one, and covered it with several layers of soil. Next, water it again. With the experience of growing soybeans, I then planted 60 mung beans.

I watered them every day. After a week, some soybeans and mung beans had green spots. After another week, these soybeans and mung beans grew a little taller. I have been watering them and they are now a few centimeters tall.

I think we can find a germination rate. Germination rate = number of germinated seeds/total number of seeds*100%. So, for these two types of seeds, I require a germination rate for each.

The germination rate of soybeans: It is known that 60 soybeans were planted and 36 germinated.

Germination rate of soybean = 36/60*100%

= 3/5*100%

= 60%

Mung bean The germination rate: It is known that 60 seeds were planted and 24 seeds germinated.

The germination rate of mung beans = 24/60*100%

= 4/10*100%

= 40%

Look , I also made a table:

Category Test total number of seeds (grains) Number of germinated seeds (grains) Germination rate soybeans 603660% mung beans 602440%

Sunny day, X-month, X-day, 20xx

No watering! I quickly watered it, but it was too late. One bean sprout died, and another bean sprout luckily survived. It turns out that watering is also a task! When I looked the next day, the bean sprouts were already two centimeters long! I am delighted to see the results of my careful cultivation, not to mention how happy I am!

Wow! You don’t know if you don’t look, just take a look and jump! My bean sprouts have grown green leaves, of course! The bud stems have also grown a lot, and when measured, they are already seven centimeters high! Ha ha ha ha! The breeding results of my dignified "Cheng Botanist" are pretty good!

A few days later, my mung bean sprouts grew more leaves, emerald green, which made me jump three feet high and dance.

I put the bean sprouts in a cup with a little water. My dad said that if you put a little water, it will grow. Two days have passed, and the bean sprouts have indeed grown very luxuriantly, but there is a lot less water. Some more buds have grown on the leaves of my bean sprouts, maybe they are about to grow leaves again. Finally, I filled the cup with water and let them grow happily!

One hot summer afternoon, I felt really cool eating iced watermelon. My mother beside me told me that she often threw watermelon seeds into flower pots when she was a child. , green seedlings will grow in the cracks in the soil in the yard in a few days. I found it very interesting and planned to give it a try.

It was cloudy on Wednesday, August 18th

I found a flower pot with half a pot of soil, dug a few small holes, put the washed watermelon seeds in, and covered them. Apply a thin layer of soil and water the seeds.

I put the flower pot in the shade of the balcony and thought to myself: Let the baby watermelon sprout quickly.

Saturday, August 21st, it was cloudy and turned to showers

Three days later, a watermelon seed sprouted, and a little green bud poked out from the black shell. He raised his head as if he was saying happily: Hello, little master, I am the little watermelon baby you take good care of.

Thunderstorm on Tuesday, August 24th

I couldn’t wait to see the baby watermelon seeds early this morning, and found that several watermelon seeds had their little heads sticking out, and the one that sprouted the earliest The watermelon seeds are the tallest and have two small green buds close together. Through this watermelon seed germination, I understand that the seeds do not need sunlight before they germinate, but need the right temperature and humidity. My mother said, wait until the watermelon seeds have grown. The green seedlings can be exposed to the sun. The mystery of science is really magical. Observation diary about seed germination Part 8

Today, my mother planted mushroom seeds in the flower bed in the yard. The seeds of shiitake mushrooms are black and oval in shape, looking like small sesame seeds.

Monday, September 24th was sunny

This morning I ran out early to see if the mushrooms had sprouted. Unexpectedly, the mushrooms were like a sleepy child, hiding In the arms of Mother Mud, she refused to come out.

Tuesday, September 25 Sunny

Today I saw many small buds emerging from the flower bed, so I watered them a little. Their roots are white and transparent, with two small yellow leaves on them. They are closely together like a pair of brothers and sisters who will never be separated.

Wednesday, September 26th was cloudy

I was particularly happy this morning because the leaves of my mushroom vegetables turned green, and the first son also split into two halves and turned into Loving type.

Thursday, September 27th Rain

It was raining heavily today. At school, I was anxiously wondering: Will the seedlings be okay? When I got home in the evening, I found that the seedlings were fine and had grown a lot of leaves.

……

I love my mushroom dish!
