>>Plantarray監(jiān)測系統(tǒng)的主要優(yōu)點<<


生理學特征的監(jiān)測和數(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、鹽分或化學物質(zhì));

理想的實驗平臺:

? 全自動? 均一檢測
適用于不同類型植物精確測量
? 非破壞性? 實現(xiàn)隨機分組實驗設計

3-4周的實驗相當于4-6個月的人工工作;

操作簡單,維護費用幾可忽略;

靈活的設計能夠滿足任何溫室中不同方面的科學研究需求。

實時統(tǒng)計分析-為了數(shù)據(jù)的可靠快速分析,提供多階乘ANOVA或配對T檢驗;

實驗目的-在實驗運行中為了確保處理的效果可以獲取最優(yōu)化的實驗參數(shù);

快速定量選擇-提供植物對于不同環(huán)境需求生理反應的評級和評分的簡況;

復雜實驗通過簡要圖像呈現(xiàn)生理參數(shù)與環(huán)境條件的空間和時間關系,顯示趨勢、異常和比率。


>>Plantarray監(jiān)測系統(tǒng)應用領域<<


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)學研究等。
