Thekey differencebetween dichogamy and herkogamy is thatdichogamy refers to sequentialhermaphroditism, while herkogamy refers to the interference between male and female functions in plants.
Dichogamy and herkogamy are two phenomena that depict adaptations shown by plants forsexual reproduction. However, we can also observe dichogamy in animals. They refer to the developmental procedures of the male and female sex.

What is Dichogamy?
Dichogamy is a type of sequential hermaphroditism that takes place in fish, gastropods and plants. Sequential hermaphroditism is the process where an organism changes sex at one point of the lifetime. Thus, in this context, the organism produces the male and female gametes at different points of their life. This takes place during the reproductive cycle.
In animals, dichogamy can be of two forms.Protandryis the form in which a male turns into a female.Protogynyis the process where a female turns into a male. Here, a switch between functional organisms takes place. Moreover, in plants, dichogamy is the phenomenon where the two sexes develop at different time-lapses. However, as a whole, both male and female flowers may open up at any time. Similar to animals, the protandrous flowers develop the male parts first followed by female parts. Furthermore, protogynous flowers develop the female parts first followed by males.
What is Herkogamy?
Herkogamy is a phenomenon shown by angiosperms. The main function of herkogamy is to reduce the sexual interference between male and female function. It interferes between anther and stigma function. Moreover, herkgamy provides a spatial separation of the anther and the stigma.
有两种常见的Herkogamy形式。他们接近Herkogamy并逆转Herkogamy。接近Herkogamy是将污名放在花药上方的现象。这使得授粉剂可以首先与污名接触,然后是花药。它允许自我受益。另一方面,逆转赫尔科加米是将污名放在花药下方的布置。此外,授粉剂首先驻留在花药上,其次是污名。
What is the Difference Between Dichogamy and Herkogamy?
The key difference between dichogamy and herkogamy relies on the fact that dichogamy can be seen in both plants and animals, while herkogamy is only seen in plants. Furthermore, dichogamy refers to the sequential hermaphroditism where there is a sequential development of the male and female sex. In contrast, herkogamy refers to the interference between the male and female gametes of angiosperms.

概括– Dichogamy vs Herkogamy
二分法和Herkogamy主要是被子植物显示的改编。换句话说,这些概念围绕着被子植物中有性繁殖的概念。但是,我们也可以观察到动物中的二分法。Dichogamy解释了顺序雌雄同体的发展。相比之下,Herkogamy解释了植物中男配子(花药)和女配子(污名)的发展。它们具有不同的形式,可以进一步解释发展序列。因此,这是二分法和Herkogamy之间差异的摘要。
