Today I will be talking about whether cloves are self-pollinating & cross-pollinating. And secondly I will discuss the use of transgenic plants in agriculture.
First of all, what is the difference between self-pollinating plants and cross-pollinating plants?
Self-pollination occurs when plants are able to pollinate themselves. These plants are usually genetically Homozygous. So this is either AA or bb. Self-pollinated plants are considered as “pure line variety” in reproduction while cross-pollinated plants are not a pure line. Cross pollination occurs when pollen of one plants fertilizes the ovule of another plant.
Cloves are considered to be self-pollinating plants in Indonesia. However the clove tree has little flowers which are attractive to bees and other insects, these are responsible for the pollination. This makes cloves also a cross-pollinated plant.
The use of transgenic plants in agriculture.
I personally am of opinion that there is nothing wrong with the use of transgenic plants. Most people around the world are scared for the unknown, and the benefits of transgenic plants are unclear to most consumers. Cross-breeding has occurred many times in history and it is not something completely new to us humans. However next to the positive aspects of for instance: Better yields, disease tolerant crops and taste/looks. I understand the fear of losing biodiversity and variety.
