The influence of the coherence of far-red (730 nm) light on the functional activity of plants was studied. Blackberry explants cultivated in vitro on an artificial nutrient medium served as a biological model. The explants were irradiated with light beams with different spatial and temporal coherence. The average cell size D was taken as the discrimination threshold for the coherence length L_{coh} and the correlation radius r_{cor}. The results of irradiation were judged by the length and number of shoots formed on each explant. The greatest photoinduced effect was observed when the conditions L_{coh}, r_{cor}>D were fulfilled, i.e., when the cell fit completely in the coherence volume of the light wave field. Significant differences in growth parameters were also observed in the variants of the experiment with a constant frequency spectrum of radiation (fixed L_{coh}), but different r_{cor}. It is concluded that the correlation properties of radiation affect photoregulatory processes.
研究了远红光（730nm）的相干性对植物功能活性的影响。在人工营养培养基上体外培养的黑莓外植体用作生物学模型。用具有不同空间和时间相干性的光束照射外植体。将平均细胞大小D作为相干长度Lcoh和相关半径rcor的判别阈值。通过每个外植体上形成的芽的长度和数量来判断照射结果。当满足Lcoh、rcor>D的条件时，即当细胞完全处于光波场的相干体积中时，观察到最大的光诱导效应。在辐射频谱恒定（固定Lcoh）但rcor不同的实验变体中，也观察到生长参数的显著差异。得出的结论是，辐射的相关特性影响光调节过程。
