…Swiss pastor J. Senebier (1724-1809) proved that CO2 is necessary for the generation of O2 , and Swiss N.T. de Saussure (1767-1845) proved that organic matter is synthesized from CO2 and H2O when light is irradiated on the green parts of a plant. A little later, German plant physiologist and agronomist J. von Sachs (1832-97) conducted a wide range of physiological research on plants, including photosynthesis, and compiled it to become the founder of plant and crop physiology. In relation to photosynthesis, research results that cannot be overlooked in the fields of genetics and breeding are the works of the Englishman C. Darwin (1809-82), especially "On the Origin of Species" and "Variations of Domestic Animals and Plants," and the Austrian G.J. Mendel's (1822-84) "Experiments on Plant Hybridization" using peas as materials. …

...In 1840, the German J. F. von Liebig proposed the inorganic nutrition theory, which stated that plants grow with water, carbon dioxide, and several inorganic salts. In 1860, Julius von Sachs (1832-97) grew plants using hydroponics and demonstrated that plants needed nitrogen, phosphorus, potassium, sulfur, calcium, magnesium, and iron. Furthermore, by 1954, the 20th century had turned to the necessity of trace elements such as copper, zinc, manganese, boron, molybdenum, and chlorine.

…スイス人牧師スヌビエJ.Senebier(1724‐1809)はO2が発生するにはCO2の存在が必要であるとし,スイス人ソシュールN.T.de Saussure(1767‐1845)は植物の緑色部分に光を照射すると,CO2とH2Oから有機物が合成されることを証明した。それよりしばらく後の,ドイツ人植物生理学者さらに農学者ともいうにふさわしいザックスJ.von Sachs(1832‐97)は,光合成を含めて,広く植物の全般にわたる生理学研究を行い,それを取りまとめた植物・作物生理学の祖述者となった。光合成の研究に対して遺伝・育種分野で見落とすことのできない研究成果は,イギリス人C.ダーウィン(1809‐82)の諸業績,とくに《種の起原》《飼養動植物の変異》やオーストリア人G.J.メンデル(1822‐84)のエンドウを材料とした〈植物雑種の研究〉である。…
