[Problem] The present invention seeks to provide a composition for plants that is highly safe and that contributes to early harvesting, increasing yield, and increasing added value of crops. Specifically, the present invention provides a yeast extract that, by addition to a foliar surface spray or to soil or water, provides an effect of promoting growth, an effect of root lengthening, an effect of improved taste, and an effect of increased amino acid content of a plant. A substance obtained from yeast that is edible and considered to be safe is preferred as the yeast extract. [Means for Solving the Problem] A yeast extract having a peptide content of 5 wt % or more and an RNA content of 5 wt % or more is sprayed onto or provided as fertilizer to a plant. The yeast extract is preferably derived from, which is edible and considered to be safe.

[Problem] To provide a phospholipid &#x3b1;-linolenic acid composition of consistent quality and having a stable supply of source material, with focus on Torula yeast, which is edible and recognized as safe, in order to resolve issues with omega 3 sources. [Means for Solving the Problem] As a result of intensive study to resolve the above-noted issues, the inventors of the present invention have discovered that a phospholipid &#x3b1;-linolenic acid composition can be obtained using residue of yeast extract extracted from Torula yeast (), for example, which is currently produced in large quantities for application in foods, and so arrived at the present invention.
