Historia Plantarum was first translated into Latin by Theodorus Gaza; the translation was published in 1483.
A germination rate experiment. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...

When the plant is grown from cuttings, the first harvest can take place 6–8 months after planting. Often, the fruits are not produced in the first year, and the yield is generally low during the first few years. By year two, it produces around 300 pods, by year three around 400–500. A good tree can yield 1,000 or more pods. [16]
Even so, botany was greatly stimulated by the appearance of the first "modern" textbook, Matthias Schleiden's (1804–1881) Grundzüge der Wissenschaftlichen Botanik, published in English in 1849 as Principles of Scientific Botany. [94] By 1850, an invigorated organic chemistry had revealed the structure of many plant constituents. [95]

In 1893 over 90,000 seeds were supplied to planters throughout Ceylon, in 1900 there was approximately 405 hectares (1,001 acres) of rubber being cultivated and by 1923 there was over 180,085 hectares ...
