Thomas Andrew Knight

Born 12 Aug 1759; died 11 May 1838 at age 78.British horticulturalist who initiated the field of fruit breeding, experimental horticulture while also studying plant physiology with botanical experiments. He made studies on the movement of sap in plants, the nature of the cambium, and phototropism in tendrils. To investigate the geotropism of roots and stems, he invented a machine, rotating to simulate gravity with centrifugal force in either horizontal or vertical position. In each case, he found the roots grew outwards and the stems inwards towards the centre. Forty years before Mendel, he studied the effects of pollen in the garden pea on seed characters. In horticulture, he investigated controlled environmental culture (greenhouses), plant nutrition, fertilization, and pest control.«
