Abstract

Ficus tikoua is one of a special species in genus Ficus, Moraceae, which characterized by its creeping vine structures. Generally, there are two different types of plants in the species: the commonly mistakenly known 'Male Ficus' which is edible, and the other hypothetical 'Female Ficus', which are not edible. It is difficult to distinguish them through the outer appearance like through stems characters or leaves shapes. Botanically, these two are corresponding to the 'normal inflorescence' syconia and 'gall flowers inflorescence' syconia. Currently, most studies confined to the former one, while the characteristics of the latter, as well as the differences between the two has not yet been reported. In this experiment, leaf epidermis microscopic characteristics (number of stoma, pore size, existence of cystoliths) were observed and compared between the two. The results showed that: 'male and female inflorescence' has larger stoma (average size of 39.55 m long and 29.13 m wide) but has a smaller density (2420/mm2); In addition, two strains both have obvious linear stalactitic structure with 17.10 m in width. The cell size has little difference between the two. Obvious anatomical differences were observed in the fruit: 'male and female inflorescence' has a clear structure for stamens and pistils, but the quantities of pistils with lateral stigma and fused bracts are much higher than stamens. The 'gall Flower' plants have no obvious typical inflorescence structure, a uniform rod protruding epidermis, and occasionally lateral style, a slender, but with not obvious ovary. These results could provide basic information for the understanding of these wild fruit resources.
