Description
本発明は、オオバの出蕾抑制方法およびイチゴの休眠抑制方法に関する。 TECHNICAL FIELD The present invention relates to a method for suppressing the emergence of psyllium and a method for suppressing dormancy of strawberries.
オオバは、日照時間が短くなると出蕾して花をつける。そのため、日照時間が短くなる冬季においても、収穫可能な葉を継続して形成させて、葉の収量を増加させるためには、出蕾を抑制する必要がある。また、イチゴは、冬季に休眠状態となり、生育が停止する。そのため、冬季に葉の展開を促進して株あたりの光合成量を増加させ、果実収量の増加を図るためには、休眠を抑制して覚醒状態を維持させる必要がある。 The plant will come and flower when the sunshine hours are short. For this reason, even in winter when the sunshine hours are short, it is necessary to suppress drought in order to continuously form harvestable leaves and increase leaf yield. Strawberries become dormant in winter and stop growing. Therefore, in order to promote leaf development in winter to increase the amount of photosynthesis per strain and increase fruit yield, it is necessary to suppress dormancy and maintain an arousal state.
従来、オオバの出蕾を抑制する方法、またはイチゴの休眠を抑制する方法として、電照栽培が行われている。前記電照栽培には、従来、白熱灯または蛍光灯が使用されている（非特許文献１および２参照）。 Conventionally, electric cultivation has been carried out as a method for suppressing the emergence of psyllium or a method for suppressing dormancy of strawberries. Conventionally, an incandescent lamp or a fluorescent lamp is used for the electric cultivation (see Non-Patent Documents 1 and 2).
しかし、前記従来の電照栽培には、例えば、病害防除効果、生育促進効果、害虫抑制効果、品質向上効果など、収量増加において必要なその他の効果はない。そのため、前記従来の電照栽培においては、電照とは別に、病害防除などのための薬剤、設備および作業が必要であり、コストがかかる上に効率が悪いという問題がある。前記病害防除効果などを備えつつ、さらにオオバの出蕾抑制効果またはイチゴの休眠抑制効果を得ることができる技術があれば、コストを減らし、かつ、より効率よく栽培でき、さらなる収量の増加を図ることができる。また、前記従来の電照栽培では、オオバにおいて、細胞間の接着および固化、ならびに細胞壁の硬化を担うリグニンの蓄積を促進することができないという問題がある。 However, the conventional electric cultivation does not have other effects necessary for increasing the yield, such as a disease control effect, a growth promotion effect, a pest control effect, and a quality improvement effect. Therefore, the conventional electric cultivation requires a chemical, equipment and work for disease control and the like separately from the electric lighting, and there is a problem that it is costly and inefficient. If there is a technology that can obtain the effect of controlling the emergence of psyllium or the effect of suppressing the dormancy of strawberries while having the above-mentioned disease control effect, etc., it is possible to reduce costs and cultivate more efficiently, and further increase the yield. be able to. In addition, in the conventional electric cultivation, there is a problem that the accumulation of lignin responsible for cell-cell adhesion and solidification and cell wall hardening cannot be promoted.
なお、前記の問題は、本発明者が検討し、見出したものである。 The above problems have been studied and found by the present inventors.
そこで、本発明は、病害防除効果、生育促進効果、害虫抑制効果および品質向上効果を備えつつ、出蕾抑制効果を得ることが可能なオオバの出蕾抑制方法、ならびに、病害防除効果、生育促進効果、害虫抑制効果および品質向上効果を備えつつ、休眠抑制効果を得ることが可能なイチゴの休眠抑制方法を提供することを目的とする。さらに、本発明は、オオバのリグニンの蓄積を促進することが可能なオオバのリグニン蓄積促進方法を提供することを目的とする。 Therefore, the present invention provides a method for controlling the emergence of psyllium which can provide a pail control effect, a pest control effect, a growth promotion, and a disease control effect, a growth promotion effect, a pest control effect and a quality improvement effect. It aims at providing the dormancy suppression method of the strawberry which can obtain a dormancy suppression effect while providing an effect, a pest suppression effect, and a quality improvement effect. Furthermore, an object of the present invention is to provide a method for promoting the accumulation of psyllium lignin that can promote the accumulation of psyllium lignin.
前記目的を達成するために、本発明のオオバの出蕾抑制方法は、オオバに緑色光を照射して、前記オオバの出蕾を抑制することを特徴とする。 In order to achieve the above object, the method for suppressing the occurrence of buckwheat according to the present invention is characterized in that the sunflower is irradiated with green light to suppress the output of the buckwheat.

次に、本発明のオオバのリグニン蓄積促進方法について説明する。 Next, the method for promoting lignin accumulation of psyllium according to the present invention will be described.
前述のように、本発明のオオバのリグニン蓄積促進方法は、オオバに緑色光を照射することを特徴とする。 As described above, the method for promoting the accumulation of psyllium lignin according to the present invention is characterized by irradiating greens with green light.

本発明者は、研究の結果、オオバのリグニンの蓄積の促進が、斑点病発生及び水分減少の少なくとも一方の抑制に繋がることを見出した。リグニン蓄積により、オオバの細胞間の接着が強まり、細胞壁が強化される。そして、細胞壁が強化されることにより、斑点病の感染が抑制され、また、水分の減少が抑制されると推察される。 As a result of research, the present inventor has found that promotion of the accumulation of psyllium lignin leads to suppression of at least one of the occurrence of spot disease and water loss. Accumulation of lignin strengthens the adhesion between the cells of Psyllium and strengthens the cell wall. And it is guessed that the infection of a spot disease is suppressed and the reduction | decrease of a water | moisture content is suppressed by strengthening a cell wall.
斑点病が発生したオオバは、商品として出荷できず、収穫後、廃棄処分される。また、収穫時には斑点病が発病していなくても、流通段階で発病することがあり、その場合、市場、店頭または消費者等からクレームが生じるおそれがある。また、水分が減少したオオバは、萎れが出るため、商品価値が下がってしまう。したがって、オオバの斑点病の発生を抑制すること、および、収穫後の水分減少を防ぐことは、オオバの栽培にとって重要な課題である。 The plantains with spot disease cannot be shipped as commodities and are discarded after harvesting. Moreover, even if spot disease does not occur at the time of harvest, it may occur in the distribution stage, and in that case, there is a risk that a complaint will be generated from the market, storefront, consumer, or the like. In addition, barley with reduced moisture is wilted, resulting in a decline in commercial value. Therefore, it is an important issue for the cultivation of grasshoppers to suppress the occurrence of leaf spot disease and to prevent water loss after harvesting.

The dormancy suppression effect by light irradiation was measured. The irradiation light intensity was 0.2 to 0.4 μmol / m 2 / s. As the green light source, a green LED bulb and a green LED rope light were used. With respect to the green LED bulb, a row of green LED bulbs arranged in one vertical row and a row of two rows arranged in two rows were provided in the irradiation area.

In a vinyl greenhouse, we planted the evergreen (Kohoku native species) on May 28, 2011, with an irradiation light intensity of 0.4 to 1.1 μmol / m 2 / s and an irradiation time of 1 to 2 hours. Light was radiated every day until the end of December 2011, and fertilizer was investigated. A green LED was used for the green light irradiation.
また、比較例として、緑色ＬＥＤに代えて、白熱灯を使用し、白熱灯では照射光強度を０．５〜１．１μｍｏｌ／ｍ２／ｓとした以外は同様にして、出蕾を調査した。 In addition, as a comparative example, an incandescent lamp was used instead of the green LED, and the incandescent lamp was examined in the same manner except that the irradiation light intensity was changed to 0.5 to 1.1 μmol / m 2 / s. .
その結果、緑色光を照射した区域では、５月末の定植から１２月上旬まで出蕾は見られなかった。また、緑色光を照射した区域において、一部（植物体の陰になり照度が低くなる場所）で、日長の最も短くなる１２月中旬（冬至）に出蕾が見られたが、これらの現象は白熱灯でも見られたことから、緑色光は白熱灯と同等以上の出蕾抑制効果があることがわかった。 As a result, in the area irradiated with green light, no buds were seen from the end of May to the beginning of December. In addition, in the area irradiated with green light, in some areas (the place where the illuminance is low due to the shade of the plant body), we found out in mid-December (winter solstice) when the day length was the shortest. Since the phenomenon was also observed with incandescent lamps, green light was found to have an output suppression effect equivalent to or better than incandescent lamps.

In a vinyl greenhouse, with an irradiation light intensity of 0.4 to 1.1 μmol / m 2 / s and an irradiation time of 1 to 2 hours, green light is emitted every day from May 28, 2011 to the end of December 2011. We studied the effects of green light irradiation on the lignin accumulation in the grasshopper. In this example, the number of samples was n = 5.
平成２３年９月２７日に前記オオバを採取し、改良Ｗｉｅｓｎｅｒ試薬（フロログリシノール飽和溶液／５％ＨＣｌ）を各３ｍｌ滴下し染色した。その後、オオバの葉片をシャーレに入れ、染色３０分後の染色強度を、葉脈全体が染色された場合は「染色濃」とし、１／２程度染色された場合は「染色中」とし、１／４程度染色された場合は「染色薄」とし、染色が見られない場合は「染色なし」として、４段階で評価した。 On September 27, 2011, the plant was collected, and 3 ml of each improved Wiesner reagent (saturated phloroglicinol solution / 5% HCl) was dropped and stained. After that, put the leaves of the donkey into a petri dish, and the staining intensity after 30 minutes of staining is set as “stained” when the whole vein is stained, “stained” when stained about ½, In the case of about 4 staining, "dyeing was thin", and when no staining was observed, "no staining" was evaluated in 4 stages.
また、比較例として、緑色ＬＥＤに代えて、白熱灯および赤色ＬＥＤを使用し、白熱灯では照射光強度を０．５〜１．１μｍｏｌ／ｍ２／ｓとし、赤色ＬＥＤでは照射光強度を２．７〜６．３μｍｏｌ／ｍ２／ｓとした以外は同様にして、オオバのリグニン蓄積量を調べた。 In addition, as a comparative example, incandescent lamps and red LEDs are used instead of green LEDs. Incandescent lamps have an irradiation light intensity of 0.5 to 1.1 μmol / m 2 / s, and red LEDs have an irradiation light intensity of 2 The amount of accumulated lignin in psyllium was examined in the same manner except that the amount was 0.7 to 6.3 μmol / m 2 / s.
その結果を、図５に示す。図５に示すように、白熱灯照射および赤色ＬＥＤ照射の場合、「染色中」の割合が全体の２０％にとどまり、また、「染色濃」の結果は見られなかったのに対し、緑色ＬＥＤ照射の場合、「染色濃」が２０％、「染色中」が４０％見られた。また、図６に、緑色ＬＥＤ照射のオオバおよび白熱灯照射のオオバのリグニン染色結果の写真を示す。図６において、右側が緑色ＬＥＤ照射のオオバのリグニン染色結果を示す写真であり、左側が白熱灯照射のオオバのリグニン染色結果を示す写真である。図６において、ＡおよびＡ´で示す領域は、染色が見られた領域である。図６に示すように、白熱灯照射のオオバよりも、緑色ＬＥＤ照射のオオバの方が、染色された領域が広かった。これにより、緑色光をオオバに照射することで、リグニンの蓄積が促進されることがわかった。 The result is shown in FIG. As shown in FIG. 5, in the case of incandescent lamp irradiation and red LED irradiation, the ratio of “dyeing” remained at 20% of the whole, and the result of “dyeing dark” was not seen, whereas the green LED In the case of irradiation, 20% “stained” and 40% “staining” were observed. Moreover, the photograph of the lignin dyeing | staining result of a green LED irradiation and the incandescent lamp irradiation is shown in FIG. In FIG. 6, the right side is a photograph showing the result of green LED-irradiated mackerel lignin staining, and the left side is a photograph showing the incandescent lamp-irradiated mackerel lignin staining result. In FIG. 6, areas indicated by A and A ′ are areas where staining is observed. As shown in FIG. 6, the stained area was larger for the green LED irradiated overs than the incandescent irradiated overs. Thus, it was found that the accumulation of lignin was promoted by irradiating green grass with green light.
