Pollination System and ex Situ Fruit Set in Ceropegia juncea Wight (Apocynaceae)-an Endemic Species of India

Pollination in the species of Ceropegia juncea Wight (Apocynaceae: Ceropegiae) in Southern India is discussed based on observation from ex situ grown plants. The study confirmed pollinators are small, mostly female Dipteran flies, ca 3 mm long, which carry pollinaria on the proboscis. The most important factors for an insect to effect pollination appear to be the appropriate overall size, mouth...

A Set of 20 New SSR Markers Developed and Evaluated in Mandevilla Lindl.

Mandevilla is an ornamental crop with a bright future worldwide because of its high commercial acceptance and added value. However, as with most ornamental species, there are few molecular tools to support cultivar breeding and innovation. In this work, we report the development and analysis of 20 new Simple Sequence Repeat (SSR) markers in Mandevilla. Microsatellites were isolated from two enr...

Seedless Fruit Production by Hormonal Regulation of Fruit Set

Seed and fruit development are intimately related processes controlled by internal signals and environmental cues. The absence of seeds is usually appreciated by consumers and producers because it increases fruit quality and fruit shelf-life. One method to produce seedless fruit is to develop plants able to produce fruits independently from pollination and fertilization of the ovules. The onset...

Vessels in Some Apocynaceae

In the present investigation vessels of 24 species of the family Apocynaceae have been studied. Lot of variation exist in the size and shape of vessels, number of perforation plates and intervascular thickening of walls in the taxa of Apocynaceae.
