    Photosynthetic activities of the sago palm (Metroxylon sagu Rottb.) were studied to find out its sensitivity to changes in ambient air temperature. The minimum ambient air temperature designed for the experiment was 25–29 °C, while the higher end was 29–33 °C. Several photosynthetic parameters were studied to support our analysis in sago photosynthetic activity, including diurnal leaf gas exchange, assimilation rate vs. CO2 concentration, leaf greenness, leaf chlorophyll content, and photosynthetic rate vs. irradiance. We found that sago palm photosynthetic activity tends to be more sensitive to minimum than to maximum ambient air temperature. The plants exposed to higher air temperatures had dark green leaf color associated with higher rates of diurnal photosynthesis, chlorophyll content, and rubisco limited photosynthetic activity. They also exhibited higher trend in optimum irradiance absorption level. Consequently, maximum light energy dissipation occurred at higher temperatures.

  14. Evaluating sago palm (Metroxylon sagu Rottb.) photosynthetic performance in waterlogged conditions: utilizing pulse-amplitude-modulated (PAM) fluorometry as a waterlogging stress indicator Reviewed

    Photosynthetic performance of sago palm (Metroxylon sagu Rottb.) was evaluated in normal and waterlogged conditions. Net assimilation rate (AN), light response curve of net assimilation rate (AN/I) and pulse-amplitude modulation fluorescence vs. irradiance (PAM/I), leaf water potential, leaf chlorophyll content and leaflet area were measured. AN was higher in a particular period of waterlogging than in the normal condition. However, prolonged waterlogging (more than two months) negatively affected sago palm photosynthetic capacity. This was indicated by reduction in several photosynthetic parameters such as AN, maximum value of AN obtained at maximum irradiance (AN ( I max)), quantum yield at zero to 200 µmol m−2 s−1 irradiance (ϕ( I o_ I 200)), asymptotic photosynthetic efficiency (αo), and maximum electron transport rate (ETRmax). The plants experiencing waterlogging produced high qNmax and NPQmax values. Prolonged waterlogging period also caused significant reduction in leaf water potential (ψleaf) and photosynthetic pigments content. Normal soil conditions with a sufficient amount of water are preferable in order for the plant to generate higher photosynthetic capacity and facilitate stable sago production.

    Salt stress is becoming a serious problem in food production field. To find sources of salt tolerance, we screened 74 accessions of adzuki bean (Vigna angularis) and 145 accessions of cross-compatible wild relatives (seven species). We performed the primary screening in soil culture and the secondary screening in hydroponic culture, and identified JP205833 of V. riukiuensis (strain 'Tojinbaka') and JP107879 of V. nakashimae (strain 'Ukushima') as the valuable source of salt tolerance. We found these two strains had different salt tolerance mechanism, where 'Ukushima' prevented Na+ accumulation in leaves by filtering Na+ in roots and stems, while 'Tojinbaka' accumulated Na+ throughout the whole plant body. We also found 'Tojinbaka' and 'Ukushima' could retain photosynthesis even under salt stress. In addition, 'Ukushima' and especially 'Tojinbaka' showed even better growth in a salt-damaged field in Fukushima, Japan where soybean cultivar 'Tachinagaha' could not survive. Since both salt tolerant strains are cross-compatible with adzuki bean, our results will facilitate developing salt tolerant cultivar by introducing two different mechanisms of salt tolerance.

    &lt;p&gt;In order to develop a high-yielding culture method for wheat we examined the effects of a higher top to basal nitrogen dressing ratio (HTBD) on the growth and yield of the new lodging tolerant variety "Satonosora" for two years. The reduced basal dressing accompanied with increased top dressing, increased the leaf area index (LAI) after jointing stage, and maintained a high net assimilation rate (NAR) during the late ripening period resulting in increased dry matter production. On the other hand, smaller stem number due to reduced basal dressing and plentiful nitrogen top dressing at the jointing stage were considered to alleviate competition of assimilate and nitrogen among stems and improved stem survival rate, resulting in both larger panicle number and panicle size. High NAR during the late ripening period might also increase the 1000 grain weight. As a result of the increased dry matter production and yield components, a HTBD increased the yield of wheat by 15 - 50%. On the other hand, some problems hindering practical use were clarified; delay of maturation, decline in the apparent quality, excess grain protein content, and acceleration of soil acidification.

    Photosynthetic activities of the sago palm (Metroxylon sagu Rottb.) were studied to find out its sensitivity to changes in ambient air temperature. The minimum ambient air temperature designed for the experiment was 25–29 °C, while the higher end was 29–33 °C. Several photosynthetic parameters were studied to support our analysis in sago photosynthetic activity, including diurnal leaf gas exchange, assimilation rate vs. CO2 concentration, leaf greenness, leaf chlorophyll content, and photosynthetic rate vs. irradiance. We found that sago palm photosynthetic activity tends to be more sensitive to minimum than to maximum ambient air temperature. The plants exposed to higher air temperatures had dark green leaf color associated with higher rates of diurnal photosynthesis, chlorophyll content, and rubisco limited photosynthetic activity. They also exhibited higher trend in optimum irradiance absorption level. Consequently, maximum light energy dissipation occurred at higher temperatures.

    Photosynthetic performance of sago palm (Metroxylon sagu Rottb.) was evaluated in normal and waterlogged conditions. Net assimilation rate (AN), light response curve of net assimilation rate (AN/I) and pulse-amplitude modulation fluorescence vs. irradiance (PAM/I), leaf water potential, leaf chlorophyll content and leaflet area were measured. AN was higher in a particular period of waterlogging than in the normal condition. However, prolonged waterlogging (more than two months) negatively affected sago palm photosynthetic capacity. This was indicated by reduction in several photosynthetic parameters such as AN, maximum value of AN obtained at maximum irradiance (AN ( I max)), quantum yield at zero to 200 µmol m−2 s−1 irradiance (ϕ( I o_ I 200)), asymptotic photosynthetic efficiency (αo), and maximum electron transport rate (ETRmax). The plants experiencing waterlogging produced high qNmax and NPQmax values. Prolonged waterlogging period also caused significant reduction in leaf water potential (ψleaf) and photosynthetic pigments content. Normal soil conditions with a sufficient amount of water are preferable in order for the plant to generate higher photosynthetic capacity and facilitate stable sago production.

    Salt stress is becoming a serious problem in food production field. To find sources of salt tolerance, we screened 74 accessions of adzuki bean (Vigna angularis) and 145 accessions of cross-compatible wild relatives (seven species). We performed the primary screening in soil culture and the secondary screening in hydroponic culture, and identified JP205833 of V. riukiuensis (strain ‘Tojinbaka’) and JP107879 of V. nakashimae (strain ‘Ukushima’) as the valuable source of salt tolerance. We found these two strains had different salt tolerance mechanism, where ‘Ukushima’ prevented Na+ accumulation in leaves by filtering Na+ in roots and stems, while ‘Tojinbaka’ accumulated Na+ throughout the whole plant body. We also found ‘Tojinbaka’ and ‘Ukushima’ could retain photosynthesis even under salt stress. In addition, ‘Ukushima’ and especially ‘Tojinbaka’ showed even better growth in a salt-damaged field in Fukushima, Japan where soybean cultivar ‘Tachinagaha’ could not survive. Since both salt tolerant strains are cross-compatible with adzuki bean, our results will facilitate developing salt tolerant cultivar by introducing two different mechanisms of salt tolerance.

    本学実験圃場内の水田土壌を用いて、酸性土壌条件をつくり出すための方法、並びに指示薬を用いて視覚的に土壌pHの変化を調査する方法を検討するとともに、土壌pHに対する日本型イネ品種の生育反応の差異を調査比較し、以下の結果を得た。
    1.土壌の酸性化とアルミニウム含量
    (1)土壌酸性化の検討
    埴壌土水田土壌(pH5.94)に硫酸(36N)を添加し、pHの変化を調査したところ、土壌100gのpH変化は次のような指数式で表せることが明らかになった。
    y=5.834e^<-1.889x> R^2=0.922
    (2)人工酸性土壌のアルミニウム含量
    上記の方法でpH3.90〜5.94の範囲で5段階のphが異なる土壌を設定し、yUANの方法により置換性アルミニウムを測定したところ、pH5.94では検出されず、pH3.90では11.85mg/100gの置換性アルミニウムが検出された。
    2.ブロムフェノールブルーによる土壌pHの観察
    通常ブロムフェノールブルーは0.1gを20mlのエタノールに溶解した後に100mlに調製するが、イネの発芽趣旨は極僅かでもエタノールを含む培地では生長が著しく阻害された。そこで、エタノールを用いずにブロムフェノールブルーを調製し、土壌に混入したところ、土壌は十分に染色され、pHの違いがはっきりと観察された。
    3.土壌pHに対する日本型イネの生育反応の品種間差
    日本型イネ10品種を用いて、上記のphの範囲における草丈、最長根長、地上部・地下部乾物重を調査したところ、pHに対する核形質の反応から次の3グループに分類できた。
    ・対アルミニウム性小:地上部・地下部とも生育阻害が小さい(ツクバハタモチ)
    ・対アルミニウム性中:地上部のみ生育が阻害される(コシヒカリ、ヤマヒカリ)
    ・対アルミニウム性大:地上部・地下部とも生育が阻害される(越路早生、他)

    イネの葉身構造変化を伴わずに,光合成機能を高め得る施肥法の開発を指向し,一時的に高濃度の窒素肥料を施用した場合の影響を調査した.その結果,2300ppmN,12時間の処理によって,葉身の薄化拡大を伴わないで葉面積当たり窒素含有量を高め得ることが明らかになった.一方,この処理による各部位の乾物重当たり窒素含有量の変化を調査したところ,葉身部に比較して葉鞘+茎部においてその増大が大きいことが,また,根部では他の部位に比べて増大程度が小さいことが明らかになった.そして,この処理を移植直前に行った苗を移植したところ,小肥条件において移植後約2〜3週間の純同化率,相対生長率が高まり,有効化する低次分げつの発生が促進され,穂数の増加を通じた1株穎花数の増加によって増収につながることが明確になった.さらに,本処理の効果は品種によって異なり,比葉面積が本来的に小さい品種において,処理による葉面積当たり窒素含有量の増大程度が大きく,移植後の生育促進効果が大きいことが明らかになった.他方,一時的な高培養液濃度条件下において,品種の違いによる窒素吸収の差異を窒素形態別に調査したところ,NH_4^+吸収量には統計的に有意な品種間差は認められなかった.それに対して,NO_3^-吸収量には明確な品種間差が認められること,また,その差異はインド型,日本型という生態型の別とは対応関係がないことが明らかになった.

    アンモニア処理による麦稈の消化率の増加は、その柔細胞壁や厚壁細胞壁の内腔表面を覆う膜状構造の脆弱化や細胞壁内部への機械的損傷による、ルーメン微生物の飼料片への付着助長と密接に関連していることを明らかにした。この強固な膜状構造は木材の仮導管細胞壁に認められるwarts layerとは形状的に異なることから、個々の細胞が枯死する時に生活残渣とおぼしき堆積物が細胞壁内腔く覆ったものであることを電顕法で明らかにした。また、アンモニア処理稈ATAg染色による呈色性の低下を認め、無処理ならびにアンモニア処理稈からの水ならびにメタノール抽出区分の成分組成やIR分析から、ヘミセルロース側鎖に置換するアセチル基の解離などによる構造の単純化が呈色反応試薬に対するsensitivityの増加をもたらしているとし、アンモニア処理による構造性多糖の溶解と消化性改善効果との関係を否定した。アンモニア処理稈と無処理稈への粉体X線回折において、アンモニア処理によるセルロース結晶化度の低下(約20%程度)が認められた。これまで、水酸化ナトリウム処理やアンモニア処理によるセルロース結晶性への影響は認めておらず、本研究において初めて、その作用機作として解明された。さらに細胞壁の保水性や膨潤性の増大(アルカリ加水分解による効果)も観察された。両処理稈から抽出した磨砕リグニンの物理化学的特性と組織細胞壁のVis/UV顕微分光解析を行い、その作用効果は、主として、リグニン末端アルデヒド基への求核反応によること、平均分子量、フェノール性水酸基、メトキシル基などの基本骨格への影響はきわめて微小であることを明らかにした。
    以上のことから、ルーメン微生物の飼料片への付着助長、セルロースの非結晶領域の拡大や細胞壁の膨潤性の増大とがアンモニア処理による大麦稈の消化性改善と密接に関連していることを明らかにした。
