I have seen this plant in the paderu forest region and the inflorescences with various shpaes and sizes.
An Inflorescence is a group or cluster of flowers arranged on a stem or twig of a plant.inflorescence may be present on axial or terminal positions of the plant.size ,shape & no.of flowers on inflorescence vary from plant to plant. Types of inflorescence : Recemose, Cymose,& Special type.Catkin is the special type of inflorescence. It is only present in Amentiferae members.The fruiting stage of an inflorescence is known as infructescence.
Inflorescence: Spikelets arranged on a common branching system (panicle, raceme, spike).
As pointed out above ibfloresecnces is is cluster of flowers and there are many types,You need to sprcify which typr of infloresence you are inyterested to seek a suitable answer
Thank you Prof. Bir Bahadur for your kind response, I have seen different shape and size of cluster or inflorescences on the same plant ( visibility is not clear in the picture), My doubt is why this much variations are occur, is it due to environmental or other reasons.
Your quetions is unclear specify the type of infloresence so that comments can be madec like hypanthodium of Fig, cyathium of Euporbia etc
I do not know what a species is on this picture, but certainly you can see there are problems with inforescence development. In my opinion there is a flowering reversion case. Some parts of inflorescences have a different architecture; there are formed a vegetative parts instead flowers one.
There is no clarity in your question and where is the infloresrsence?????
I have taken this photograph during my collection of fresh water algal forms.in Paderu. I am thinking this inflorecences is dirrerent from normal types of inflorences.
It is gradient of growth regulators which makes inflorescence on a vegetative shoot and turns it intofloral apex
Prof Ashwani Kumar is right, Yes this happens in mant species foue example Leonotis of Lamiaceae,Aftwer all flower is a modified shoot.!!!!
Thanks Prof Bir Bahadur you have vast experience and thanks to you for supporting my contention.
Hi Geddada,
1. Different plant species can have different type of inflorescences (see attached picture).
2. Variations in the sizes (and other characterics) of inflorescences were reported. Please see the attached paper #1. Variations can even occur within a inflorescence ("intra-inflorescence"). See the attached paper #2.
3. The variations (such as sizes) were hypothesized as the results from the completion of resources (see the two papers). The variations not only affect pollination from pollinators (ex. large flowers usually attract more pollinators). It also has the impact on the populations of the pollinators depending on those fruits for propagate. See the first paper about the impact of variations of fig plant inflorescences on their pollinator 'fig wasps'.
Thank you Dr.Yuan-Yeu Yau for your kind information along with relevant publications
Hi Geddada,
Except environment factors, mutations of genes controlling the inflorescence architectures are also an important factor. In the attached paper, it describes that two important inflorescence architecture, 'S' and 'AN', in the Nightshade (Solanaceae) species. The loss of either gene delays flower formation, resulting in additional branching. Independently arisen alleles of 's' account for inflorescence variation among domesticated tomatoes, and an stimulates branching in pepper plants that normally have solitary flowers.
