Physalis Angulata

An optimal plant propagation method of Physalis angulata L., a medicinally important herbaceous plant species has been developed using axillary meristem explants. Shoot bud proliferation was initiated from axillary meristem explants cultured on MS medium supplemented with various concentrations of 0.5-2.5mg/L/(BAP)/(Zeatin)/(KIN). The maximum in vitro response of shooting frequency of explants (88.1%) and shoots per explant (42) was achieved with medium containing 1.0mg/L BAP. Multiple shoot culture was established by repeated subculturing of the shoot buds of axillary meristems on shoot multiplication medium. Among the subculture media BAP in combination with 1.5mg/L (IAA)+0.25mg/L(GA3) produced maximum shoots per explant (128±0.29) after two weeks of culture. Effective in vitro shoot elongation and rooting was achieved on 1.0mg/L(GA3) and 1.0mg/L(IBA), respectively. Most of the generated shoots were successfully transferred to soil under field conditions. The survival percentage of the transferred plants on soil was found to be 90 per cent.  This protocol can be used for commercial propagation and for future genetic improvement studies.

The presentation of flowers on a modified stem, the inflorescence, requires the integration of several aspects of meristem behaviour. In Antirrhinum, the inflorescence can be distinguished by its flowers, hairy stem, modified leaves, short internodes and spiral phyllotaxy. We show, by a combination of physiological, genetical and morphological analysis, that the various aspects of the inflorescence are controlled by three pathways. The first pathway, depends on expression of the floricaula gene, and is rapidly and discretely induced by exposure to long daylength. Activation of this pathway occurs in very young axillary meristems, resulting in a floral identity. In addition, the length of subtending leaves and hairiness of the stem are partially modified. The second pathway affects leaf size, internode length, and stem hairiness, but does not confer floral meristem identity. This pathway is induced by long daylength, but not as rapidly or discretely as the floricaula-dependent pathway. The third pathway controls the switch in phyllotaxy from decussate to spiral and is activated independently of daylength. The coordination of these three programmes ensures that apical and axillary meristem behaviour is integrated.

Flowering Plant Species

Uttarakhand is a store house of plant genetic resources of several crop groups including ornamentals and seasonal flowering plant species. A wide range of seasonal flowering plants are being grown in the region because of its various and favourable agro-geo climatic zones. Ornamental plant enhances aesthetic value of our environment. There are 8 developmental blocks and 1082 villages in district Nainital of Uttarakhand. Nainital district, is a part of Kumaun region of Uttarakhand. It lies between 29?0.1' to 29?36' 21'' N latitude and 78?50' 53'' to 80?06' E longitude. More than 7.62 lakh population reside in 4064 km2 of geographical area of district Nainital. The district falls under sub-tropical to temperate zones. During the course of field survey (2013-2015), we came across wide range of seasonal flowering plants mostly belong to exotic origin being grown in the home gardens of natives of the region situated in different agro-ecological niches. The present study highlighted a total of 150 seasonal flowering plants with 120 genera belonging to 50 families. These were arranged alphabetically with botanical names followed by vernacular and trade name, family, origin or native place, nature, season with appropriate remarks of variation in shape, size and colour, method of propagation with economic status.
