Variability in vegetative and reproductive traits: Pulsatilla alpina apiifolia low form. The flowers of this species have many anthers and many ovules in a polycarpellary apocarpus ovary.

Potentilla aff atrosanguinea velvet red ex Tibet OUT. Due to small size of its populations, very few 0. The Apharwat population, besides having small population size and small number of reproductive individuals with most of those bearing only one flower each, was frequently visited by herbivores throughout the growing season damaging the flowers, leaves and the fruits.


Robson reported it during a visit to Kashmir in from above Gulmarg and near Thajewas above Sonamarg.

Factors controlling fruit set in hermaphrodite plants: Carpels usually2. Potential impacts of global elevated CO 2 concentrations on plants. Users of the data do not require specific permission from the authors or the publisher.

The number of deposited pollen grains as well as the aquilegka of germinated pollens starts increasing thereafter.

The aim of the Journal is to promote wildlife research and conservation action worldwide at no cost to authors, no subscription or membership cost, and no hidden cost, on a regular basis without compromising on ethics, standards and pre-requisites of scientific publications. Demography and extinction in small populations. Nomenclature and Classification Nomenclature and Classification.

Details of some important contributors. Click the names to see pictures of the plants. No seeds were formed either under apomictic or autogamous conditions Fig. Fruiting failure and limited recruitment in remnant populations of the hawkmoth-pollinated tree Oxyanthus pyriformis subsp.

The highest number 2. The slight disparity in the percent fruit set in different treatments may be a result of the damage and removal of pollen reward although the all important nectar rewards were still unaltered. In order to record the extent of variation in different traits across the studied populations, 10 randomly-selected, healthy individuals were tagged and examined weekly throughout the growing season to record the onset and duration of various vegetative phenophases sprouting, seed germinationsexual phases bud formation, anthesis, pattern of anthesisflowering period, type of dichogamy, etc.


International Journal of Botany Volume 6 4: I disagree with the inclusion of the ‘Snow Columbine’ as a ‘Red List’ species either within India or Internationally it would only be included as. The biology and ecology of endemic and widespread plants: Endemic angiosperms of Kashmir: The initiation of receptivity and its longevity was also recorded.

The seed formation starts from the month of July and continues up to September. The frequency of visitation increased with an increase in the number of flowering individuals and the number of flowers in a population. Hence the stigma receptivity gradually increases from nialis day of anthesis and reaches its peak on the 2nd day of anthesis. Related observations Show all. User specific search options User. Nevertheless, it needs to be emphasized that Kashmir Himalaya constitutes only 0.

The stigmas with germinated pollen grains were considered as receptive.
