pure water
no impurities,,so that cannot disturb the result of the experiment
The conclusion of an experiment on pollen germination would typically summarize the findings related to how different factors or variables impact the germination process, such as temperature, pH levels, or nutrient availability. It may also highlight any patterns or trends observed in the data, discuss any unexpected results, and offer insights into the conditions that promote or inhibit pollen germination.
A Stamen- to release pollen A Stigma- to receive pollen
Pollen germination and growth can be controlled by manipulating environmental factors such as temperature, humidity, and light. Chemical treatments, such as hormones or inhibitors, can also be used to regulate pollen germination and growth. Additionally, genetic manipulation can be employed to develop transgenic plants with desired pollen germination and growth characteristics.
Pollen tube germination is the process by which a pollen grain, upon landing on a compatible stigma, develops a tube that extends down the style toward the ovule in the ovary. This tube carries sperm cells from the pollen grain to fertilize the ovule, leading to seed formation. The germination process involves the hydration of the pollen grain and the growth of the tube, which is guided by chemical signals from the ovule. Successful germination is crucial for plant reproduction.
The low germination of CMS (Cytoplasmic Male Sterility) pollen can be due to various reasons such as genetic factors, environmental conditions, or improper development of the pollen grains. It can also be influenced by factors like temperature, humidity, nutrient availability, and the age of the pollen grains. Additionally, disruptions in mitochondrial function or cytoplasmic genes can also contribute to low germination rates in CMS pollen.

this is because premature pollen grain do not contain the sperm cell for fertilization. only the generative nucleus in mature pollen grain will divide mitosisly to form sperm cell for fertilization

It allows landing of pollen grains and germination of compatible pollen grains only.
Germination of the pollen grain typically occurs on the stigma of the carpel (female reproductive organ) in flowering plants. The pollen grain produces a pollen tube through which the male gametes travel to fertilize the ovule.
