Abstract

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a national stage application (under 35 U.S.C. § 371) of PCT/EP2020/057427, filed Mar. 18, 2020, which claims benefit of European Application No. 19164699.1, filed Mar. 22, 2019, both of which are incorporated herein by reference in their entirety. The present invention relates to a 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 enriched in far-red light (680 to 900 nm). The light enriched in far-red is obtained by converting light comprising a wavelength of 300 to 900 nm to light comprising a wavelength of 680 to 900 nm by means of a color converter comprising a terrylene diamide compound in a polymeric matrix material. The present invention also relates to the use of a terrylene diimide compound in a color converter for providing horticultural light comprising a wavelength of 680 to 900 nm. TECHNICAL BACKGROUND Plants need light energy for their growth and development. Important physiological processes such as photosynthesis, photomorphogenesis, photoperiodism and phototropism are based on the interaction between plants and light. Photosynthesis means the conversion of light energy into chemical energy. This is a completely distinct process from photomorphogenesis, photoperiodism and phototropism. Photomorphogenesis means the response of plants to light in the form of altered plant growth and development, photoperiodism means the response of plants to the length of day or night, and phototropism means growth of a plant toward or away from a light source. Plants use different kinds of photoreceptors to sense, evaluate and respond to light quality, quantity and direction. The photoreceptors are characterized by the wavelength of light that they perceive. For photosynthesis, plants mainly use light in the wavelength range from about 400 to 700 nm, which is called the photosynthetically active radiation (PAR), especially the blue (300 to less than 500 nm) and red (570 to less than 680 nm) wavelength range. Blue light is essential for photosynthesis and stomatal movement, and thus biomass production. Red light is essential for photosynthesis and thus biomass production. PAR radiation is perceived mainly by chlorophylls a and b and carotenoids. Responses that are not related to photosynthesis, i.e. photomorphogenetic, photoperiodic and phototropic responses, allow the plant to adjust to their environment and optimize growth. Light having wavelengths in the red (570 to less than 680 nm) and in the far-red (680 to 900 nm) part of the electromagnetic spectrum is effective in inducing a photomorphogenetic and photoperiodic response in plants. The response is mediated by photoreceptors among which the phytochrome photosystem plays an important role. The phytochrome photosystem exists in two interconvertable forms, a red light absorbing form Pr and a far-red absorbing form Pfr. The Pr form has a peak absorption at about 660 nm which, for example, is found in full sun conditions, the Pfr form of phytochrome has a peak absorption at about 730 nm which, for example, is indicative of shade. On absorbing red light, the biologically inactive Pr form converts into the biologically active Pfr form. Exposure to far-red light largely converts the Pfr form back to the biological inactive Pr form. Exposure during an extended period of uninterrupted darkness also converts the Pfr form to the inactive Pr form. Once the plants are exposed to light, both phytochrome forms are present because the absorption spectra of the Pr form and the Pfr form overlap. Both forms have also weak absorption in the blue wavelength range (300 to less than 500 nm). The phytochromes mediate a variety of photomorphological and photoperiodic responses including plant growth and development, flowering induction, plant health, concentration of plant substances, seed germination, de-etiolation, shade avoidance, circadian rhythm, etc. The responses mediated by the phytochromes are usually related to the sensing of the red (R) to far-red (FR) ratio (R/FR). Direct sunlight is rich in a red component, whereas light reflected from neighboring vegetation is depleted in red light and rich in far red light. This far-red-enriched light causes a decrease of the active Pfr form and induces plant photomorphogenetic responses such as stem elongation and leaf expansion to prevent overtopping by neighboring plants. In some situations, the elongation response is desired but in the production of ornamental flowers, often it is not. This far-red-enriched light also induces early flowering. Low fluences of red light can increase the plant resistances against diseases. For instance in tomatoes, red light can help against fungi. A growing world population makes it increasingly necessary to produce more food and, in addition, to cultivate crops even in climatically unfavourable
