Abstract

Fennel is considered as a very important spice crop with powerful therapeutic potential. An improvement in this valuable crop, selected physical mutagen (Gamma irradiation) on the seeds with five selective doses viz., 50, 100, 150, 200 and 250 Gy for break genetic consistency in narrow genetic base in Fennel crop, remunerative phenomenon of syncytes was seen in some cases, where complete chromatin was transmitted to the recipient PMC, that generates dimorphic pollen grain. Such pollen grain with varying genetic content plays a significant role in the emergence of intraspecific polyploidization of species. A curious biological process which is often observed in microsporogenesis of higher plants like, development of syncytes, cytomixis between plant cells and due to this the creation of big pollen has evolutionary relevance. The cytomictic behaviour of Foeniculum vulgare Mill. has been reported in this experiment.

茴香植物小孢子发生过程中伽马辐射诱导细胞混合的后果（Foeniculum vulgare Mill.）

摘要

茴香被认为是一种非常重要的香料作物，具有强大的治疗潜力。对这种宝贵作物的改进，在种子上选择物理诱变剂（伽马辐照），采用五种选择性剂量，即 50、100、150、200 和 250 Gy，以打破茴香作物狭窄遗传基础的遗传一致性，合胞体的报酬现象在某些情况下，完整的染色质被传递到受体 PMC，从而产生二态性花粉粒。这种具有不同遗传内容的花粉粒在物种内多倍化的出现中发挥着重要作用。在高等植物的小孢子发生中经常观察到一种奇怪的生物过程，例如合胞体的发育、植物细胞之间的细胞混合，因此大花粉的产生具有进化相关性。茴香的细胞分裂行为。已在该实验中报道过。
