最近的研究激发了人们对自然发生的电场和相关现象可能的生物学意义的更广泛兴趣。Murr 1 - 3表明，高强度电场似乎抑制草幼苗的发育;然而，他指出，早期的工作者，特别是Jorgensen和Priestley 4，Shibusawa和Shibata 5，观察到在电场条件下植物生长的增加，尽管Lund 6强调了在这个问题的早期工作中经常出现相互矛盾的结果。空气电离的生理效应已经被许多工作者研究过了。Kruegeret等人8报道，暴露于正或负电离空气中可使燕麦种子更快发芽，随后生长和干重增加;将幼苗置于955 V的正或负电场中30 cm，也可观察到生长略有增加;然而，在这些实验中，种子容器接地以防止表面电荷积累。目前的通信将注意力引向萌发种子对诱导静电荷的响应的极性的明显依赖性。
RECENT investigations have stimulated wider interest in the possible biological significance of naturally occurring electric fields and related phenomena. Murr1–3has shown that high intensity electric fields appear to inhibit development in grass seedlings; he points out, however, that earlier workers, notably Jorgensen and Priestley4, and Shibusawa and Shibata5, observed increases in plant growth under electric field conditions, although the frequent occurrence of contradictory results in much of the early work on this subject has been emphasized by Lund6. The physiological effects of air ionization have been studied by a number of workers7. Kruegeret al.8report that exposure to positively or negatively ionized air produced more rapid germination inAvena sativaseeds with subsequent increases in growth and dry weight; slight increases in growth were also noted with seedlings placed in positive or negative electric fields of 955 V over 30 cm; in these experiments, however, the seed containers were grounded to prevent the accumulation of surface charge. The present communication directs attention to an apparent dependence on polarity of the response of germinating seeds to induced electrostatic charges.
