>>Plantarray監(jiān)測(cè)系統(tǒng)的主要優(yōu)點(diǎn)<<


生理學(xué)特征的監(jiān)測(cè)和數(shù)據(jù)高通量分析,如生長速率、蒸騰速率、水分利用率、氣孔導(dǎo)度等特征;

連續(xù)控制不同的土壤和水分環(huán)境(如干旱、鹽分或化學(xué)物質(zhì));

理想的實(shí)驗(yàn)平臺(tái):

? 全自動(dòng)? 均一檢測(cè)
適用于不同類型植物精確測(cè)量
? 非破壞性? 實(shí)現(xiàn)隨機(jī)分組實(shí)驗(yàn)設(shè)計(jì)

3-4周的實(shí)驗(yàn)相當(dāng)于4-6個(gè)月的人工工作;

操作簡單,維護(hù)費(fèi)用幾可忽略;

靈活的設(shè)計(jì)能夠滿足任何溫室中不同方面的科學(xué)研究需求。

實(shí)時(shí)統(tǒng)計(jì)分析-為了數(shù)據(jù)的可靠快速分析,提供多階乘ANOVA或配對(duì)T檢驗(yàn);

實(shí)驗(yàn)?zāi)康?在實(shí)驗(yàn)運(yùn)行中為了確保處理的效果可以獲取最優(yōu)化的實(shí)驗(yàn)參數(shù);

快速定量選擇-提供植物對(duì)于不同環(huán)境需求生理反應(yīng)的評(píng)級(jí)和評(píng)分的簡況;

復(fù)雜實(shí)驗(yàn)通過簡要圖像呈現(xiàn)生理參數(shù)與環(huán)境條件的空間和時(shí)間關(guān)系,顯示趨勢(shì)、異常和比率。

非生物逆境脅迫研究,比如:干旱、淹水、營養(yǎng)、有毒物質(zhì)等脅迫研究;

在農(nóng)作物、蔬菜、樹木、藥用植物、燃料作物等方面的育種研究;

根系的土壤穿透力、水通量研究;

生物激素與養(yǎng)分研究;

生理生態(tài)學(xué)研究等。
