B Somatic embryos had no obvious suspensors.

体细胞胚具明显的极性。

This is because that the solvent polarity affects ICT process in two ways: on the one hand, the ICT state is better solvated in more polar solvent, which favors the ICT process; whereas on the other hand, the rates of non-radiative decay and intersystem crossing of the ICT state are increased, which unfavors the ICT process.

这是因为溶剂极性增大，一方面ICT态被更好地溶剂化，ICT过程活化能降低，有利于ICT过程的发生；另一方面ICT态非辐射跃迁和系间窜跃速率增大，导致ICT荧光猝灭。

When photon acts as the medium of electric field, the photon will be polarized and called photonic polaron.
