本発明においてコリンまたはコリン塩を処理する方法と
しては、稲の種子消毒後の催芽の際にコリンまたはコリ
ン塩で処理する方法が採られる。In the present invention, a method for treating rice seeds with choline or choline salts is a method of treating rice seeds with choline or choline salts during germination after disinfection.
具体的には稲の種子を消毒した後、コリンまたはコリン
塩の水溶液に稲の種子を浸漬し、加温して催芽する方法
が採られる。なお、催芽後水洗するのが好ましい。Specifically, after disinfecting rice seeds, the rice seeds are immersed in an aqueous solution of choline or choline salt, and germinated by heating. Note that it is preferable to wash the seeds with water after germination.
本発明に於いて、コリン塩とは例えば塩漬塩、リン酸塩
、ボＩＪ ＩＪン酸塩、硫酸塩、硝酸塩、ケイ酸塩、炭
酸塩等の無機塩、酢酸塩、クエン酸塩、乳酸塩、Ｌ（−
１−）酒石酸塩等の有機酸塩を意味する。In the present invention, choline salts include salt salts, phosphates, inorganic salts such as phosphates, sulfates, nitrates, silicates, carbonates, acetates, citrates, and lactic acid. Salt, L(-
1-) Means an organic acid salt such as tartrate.
これらのコリンまたはコリン塩は例えば粉末、水溶剤、
乳濁液、水性または油性懸濁液の様な通常の公知の任意
の形状に製剤したものが使用される。These choline or choline salts can be prepared, for example, in powder form, aqueous solution,
Any conventionally known formulations such as emulsions, aqueous or oily suspensions can be used.
本発明方法に詔いて、催芽時の水溶液内のコリンまたは

であり、好ましくは５００〜２ 、０００ ｐｐｍ
である。また本発明方法を実施する場合の温度は通常
の稲の種子の催芽温度が採用される。また本発明方法に
おけるコリンまたはコリン塩の処理時間は処理温度にも
よるが、一般的には１２時間から４８時間、好ましくは
２４時間から４２時間である。In accordance with the method of the present invention, the concentration of choline or choline salt in the aqueous solution during germination is generally 300-3. OOOppm
and preferably 500 to 2,000 ppm
It is. Further, the temperature at which the method of the present invention is carried out is the normal germination temperature of rice seeds. Further, the treatment time for choline or choline salt in the method of the present invention depends on the treatment temperature, but is generally from 12 hours to 48 hours, preferably from 24 hours to 42 hours.
〔発明の効果〕
本発明方法により処理した稲の種子を播種することによ

ことが可能である。[Effects of the Invention] By sowing rice seeds treated according to the method of the present invention, it is possible to raise seedlings with excellent root growth and suppress the plant height of the seedlings, so that seedlings with cold resistance can be produced. It is possible to obtain this, and it is also possible to grow healthier rice.
実施例により本発明を更に詳しく説明する。 The present invention will be explained in more detail with reference to Examples.
実施例 １
水稲の種子（品種、日本晴）４ｇを室温（１６℃）で４

０℃で２４時間浸漬して催芽した。得られた催芽種子を
３回水洗した。Example 1 4g of paddy rice seeds (variety: Nipponbare) were grown at room temperature (16°C).
8 hours, 20 ml of an aqueous solution containing 0.1 g of benlate T
After soaking in water, the rice seeds were taken out from the benlate aqueous solution, and then soaked in an 11,000 pp aqueous solution of choline chloride for 30 minutes.
Germination was carried out by soaking at 0°C for 24 hours. The obtained germinated seeds were washed with water three times.
