Abstract
a)該種子を1以上のバインダー及び1以上の活性成分を含むコーティング組成物でコーティングすること、及びb)該種子を液体中で濡らすこと、ここで該液体は、発芽を誘発するのに十分な量の水を含み、該水の量は、該種子の発芽の前に種子により実質的に全ての水が吸収されるような量である、を含む、前記方法に関する。
【選択図】図1
Description
種子と該種子を濡らす浸透性の物質との間の接触はなく、該種子は該処理の後に乾燥される必要がある。この文献は、発芽を誘発するために必要な水の全てが基本的に種子の発芽の前に吸収されるべきであることを明示的に教示しているわけではない。さらに、この文献は、該種子を濡らす前に該種子をコーティングすることを教示していない。
発芽していない種子を用意すること、及び
a)該種子を1以上のバインダー及び1以上の活性成分を含むコーティング組成物でコーティングすること、及び
b)発芽を誘発するのに十分な量の水の中で該種子を濡らすこと、ここで該水の量は、該種子の発芽の前に種子により実質的に全ての水が吸収されるような量である、
前記方法に向けられる。
第一の実施例のために、品種コシヒカリのオリザジャポニカの種子が使用された。該種子は、回転ディスクを有する30cmの回転式コ−タ−においてコーティングされた。バッチサイズは575gであった。フィルムコーティング配合物Disco AG red L200(Incotecから市販入手可能)、水及びGaucho(商標)70 WP(バイエルから市販入手可能)から10:15:12.6の重量比で混合物が製造された。該混合物は、Gaucho(商標)の投与量が12.6g/kg種子であるような投与量において、コーティングマシンに適用された。次に種子のバッチは、2時間、35℃において種子乾燥器で乾燥された。得られる水分含有量はオーブンプロトコル(130℃において4時間)で測定され、総濡れた種子重量に基づいて11.5重量%であった。
ここでWwaはグラムで表わされた添加されるべき水の重量であり、MC1は重量%で表わされた、該種子の最初の水分含有量であり、MC2は重量%で表わされた該種子の目標とする水分含有量であり、Wsはグラムで表わされた最初の種子重量(即ち、濡らす段階の前の種子の重量)である。
第二の実施例のために、オリザインディカ種子品種OMCS2000が使用された。種子は回転ディスクを有する30cmの回転式コーター中でコーティングされた。バッチサイズは、575gであった。フィルムコーティング配合物Disco AG red L200(Incotecから市販入手可能)、水及びCruiser(商標)70 WP(Syngentaから市販入手可能)から10:20:16の重量比で混合物が製造された。混合物は、Cruiser(商標)の投与量が16g/kg種子であるような投与量でコーティングマシンに適用された。次に種子のバッチは、2時間、35℃において種子乾燥器で乾燥された。得られる水分含有量はオーブンプロトコル(130℃において4時間)で測定され、総濡れた種子重量に基づいて9.5重量%であった。
第三の実施例のために、品種43A56のOSR(セイヨウアブラナ)の種子が使用された。該種子は、回転ディスクを有する30cmの回転式コーター中でコーティングされた。バッチサイズは、500gであった。フィルムコーティング配合物Disco Agroblue L204(Incotecから市販入手可能)及びCruiser(商標)OSR(Syngentaから市販入手可能)から10:17.2の重量比で混合物が製造された。混合物は、Cruiser(商標)の投与量が17.2 g/kg種子であるような投与量においてコーティングマシンに適用された。次に種子のバッチは、0.5時間、35℃において種子乾燥器で乾燥された。得られる水分含有量はオーブンプロトコル(130℃において4時間)で測定され、総濡れた種子重量に基づいて5.03重量%であった。
