Abstract
Official abstract text for this publication.
Compositions and methods of protecting plants from cold damage are provided. In particular, the invention provides compositions comprising plant-based nano- and/or micron-sized particles which, when applied to plants or plant parts such as buds, form a non-hydrophilic deposit or film with low thermal conductivity, thereby conferring protection against damage from ice nucleation and cold stress.
First claim
Opening claim text (preview).
We claim: 1. A method of preventing or limiting ice nucleation on buds of a plant, comprising the steps of selecting a plant having a plurality of buds or bud sites, wherein the plant is in a growth stage preceding a fruit set stage; spraying onto the plant an aqueous composition which includes at least one of cellulose nanocrystals (CNC) and cellulose nanofibers (CNF) extracted from wood biomass, and at least one surfactant; wherein the step of spraying is performed so as to adhere the at least one material onto the buds or bud sites of the plant forming a hydrophobic deposit such that ice nucleation is prevented or limited, and wherein said spraying is performed prior to or during the plant being exposed to freezing temperatures. 2. The method of claim 1 , wherein the at least one material is deposited on at least about 10% of the bud surface. 3. The method of claim 1 , wherein the plant is selected from the group consisting of fruit trees, vegetable crops and ornamentals. 4. The method of claim 1 , wherein the step of spraying is performed at a temperature that is below 0° C.
