8月14日,湖南省植物園開(kāi)展了2024年科普教育基地“科創(chuàng)筑夢(mèng)”聯(lián)合行動(dòng)——發(fā)現(xiàn)基礎(chǔ)科學(xué)之美?雜交水稻的第一場(chǎng)科學(xué)體驗(yàn)活動(dòng),主題為“水稻的遺傳與雜交”,20多名中小學(xué)生、家長(zhǎng)現(xiàn)場(chǎng)感受著種子的力量。
在活動(dòng)體驗(yàn)過(guò)程中,大家在指導(dǎo)老師的帶領(lǐng)下,首先觀察花的形態(tài)結(jié)構(gòu),并進(jìn)行了解剖研究。隨后使用工具模擬花卉授粉實(shí)驗(yàn),探究水稻雜交育種技術(shù)。
在完成基礎(chǔ)實(shí)驗(yàn)后,用扭扭棒模擬基因型,進(jìn)行基因配對(duì)實(shí)驗(yàn),揭秘遺傳、變異發(fā)生過(guò)程及雜交優(yōu)勢(shì)產(chǎn)生原因,體驗(yàn)中國(guó)雜交水稻從無(wú)到有、從有到高產(chǎn)、從高產(chǎn)到適應(yīng)性強(qiáng)背后的科學(xué)故事。(來(lái)源:新湖南)
On August 14, Hunan Provincial Botanical Garden carried out the joint action of "Science Creation and Dream Building" for 2024 science education bases—Discovering the Beauty of Basic Science-Hybrid Rice's First Science Experience. The theme is "Rice genetics and hybridization". More than 20 elementary and middle school students and parents were on hand to experience the power of seeds.
During the activity experience, the group, led by the instructor, first observed the morphological structure of the flower and conducted anatomical studies. The tools were then used to simulate flower pollination experiments and to explore rice cross-breeding techniques.
After completing the basic experiment, they performed a gene pairing experiment using a twister to simulate genotypes. Uncovering the process of inheritance, the occurrence of variation and the reasons for the creation of hybridization advantages. They experience the scientific story behind China's hybrid rice from scratch, from availability to high yield, and from high yield to adaptability. (翻譯:萬(wàn)姍姍)
