Swelling of and cytoplasmic streaming within the grain, germination pore expansion, and pollen tube emergence, in that order, constitute the normal germination pattern of Impatiens holstii pollen grains. This normal sequence of events becomes manifest when the pollen grains are placed on water-agar, barbituric acid-agar, and on barbital-agar media whereas this sequence of events is interfered with when the pollen grains are incubated on amytal-agar or on seconal-agar media. Evidence is presented which demonstrates that the normal sequence of events which make up the normal germination pattern of Impatiens holstii pollen grains can be separated from each other by varying the concentrations of the oxybarbiturates amytal and seconal used. Evidence is also presented which indicates that the actions of barbituric acid and the oxybarbiturates barbital, amytal, and seconal on Impatiens holstii pollen germination behaviour correlate well with certain aspects of the pharmacological literature concerning the actions of these organic compounds on the central nervous system (CNS).
籽粒肿胀、细胞质流动、萌发孔扩张以及花粉管伸出,按此顺序构成了霍氏凤仙花花粉粒的正常萌发模式。当花粉粒置于水琼脂、巴比妥酸琼脂和巴比妥琼脂培养基上时,这一正常事件序列就会显现出来,而当花粉粒在异戊巴比妥琼脂或速可眠琼脂培养基上培养时,这一事件序列就会受到干扰。有证据表明,通过改变所使用的氧巴比妥类药物异戊巴比妥和速可眠的浓度,可以将构成霍氏凤仙花花粉粒正常萌发模式的正常事件序列彼此分开。还有证据表明,巴比妥酸以及氧巴比妥类药物巴比妥、异戊巴比妥和速可眠对霍氏凤仙花花粉萌发行为的作用,与药理学文献中有关这些有机化合物对中枢神经系统(CNS)作用的某些方面密切相关。
