摘要： The invention relates to a plant cultivation method for modifying at least one agricultural property of a cultivated plant where the agricultural property is susceptible to modification by irradiating at least part of the plant with light comprising the steps of (a) providing at least one light source emitting a first spectrum comprising a wavelength of 300 to 900 nm; (b) subjecting said first spectrum to a partial or full conversion to obtain a second spectrum comprising a wavelength of 680 to 900 nm by means of at least one color converter wherein the obtained second spectrum has higher intensities of light at wavelengths of 680 to 900 nm compared to the first spectrum; and (c) irradiating at least part of the cultivated plant with the second spectrum obtained in step (b); wherein the at least one color converter comprises in a polymeric matrix material at least one terrylene diimide compound of formula (I) wherein the variables are as defined in the claims and the description. The present invention also relates to the use of said terrylene diimide compound of formula (I) in a color converter for providing horticulture light comprising a wavelength in the range from 680 to 900 nm.
