Plantarray植物高通量生理學特征監(jiān)測系統(tǒng)

一套高通量、以植物生理學為基礎(chǔ)的高精度表型系統(tǒng)，可以完成整個植物生長周期中不同環(huán)境下的SPAC因子的測量。

以色列Plant-DiTech公司的Plantarray監(jiān)測系統(tǒng)是一套高通量，以植物生理學為基礎(chǔ)的高精度表型系統(tǒng)，可以完成整個植物生長周期中不同環(huán)境下的SPAC（Soil-Plant-Atmosphere Continuum， 土壤植物大氣連續(xù)體）因子的測量。連續(xù)不間斷的獲取陣列內(nèi)所有植物的監(jiān)測數(shù)據(jù)，實時監(jiān)控和及時調(diào)整每個培養(yǎng)容器中的土壤條件，包含土壤水分、鹽分。

>>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：

? 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(shè)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(guān)系，顯示趨勢、異常和比率。

>>Plantarray監(jiān)測系統(tǒng)應用領(lǐng)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。
