Conservation And Management

Ex situ conservation by vegetative propagation was successfully established in the endemic rare balsam species Impatiens anaimudica, I. elegans, I. disotis and I. phoenicea of the Western Ghats.  The experiment was done in an open environmental nursery at Munnar exposed to constant temperature (7–24 0C) and relative humidity (70–100 %) throughout the study period.  These favourable conditions provided a suitable platform for the establishment.  We observed a significant difference in the regeneration patterns of the four species.  I. elegans started to regenerate after the 10th day of planting with high success, while I. disotis showed a 30% success rate.  After maturation all species were transplanted to natural ecosystems.

Grafting Experiment

Vegetative propagation through softwood grafting was carried out during 1994-1997 on Flacourtia montana, an endemic wild edible fruit tree of the Western Ghats, as part of its popularization and promoting cultivation programme. The grafting experiment was very successful and resulted in 78 percent success. The paper discusses the grafting success and its field performance.

Rooting trials conducted with stem cuttings and air layering in Syzygium caryophyllatum (L.) Alston, an important medicinal and fruit plant gave promising results after treatment with auxins such as IAA, IBA and NAA in different concentrations. Both stem cuttings and air layering from 10 year old plants have resulted a maximum rooting of 80% and 70% respectively through the application of IBA-1000ppm, in their natural habitats. The plants developed from stem cuttings and air layering was also survived with 90% success. Thus the standardized clonal propagation method in S. caryophyllatum through stem cutting and air layering reported for the first time can be taken as an ideal tool for the multiplication and subsequent resource base utilization of the species since the populations are prone to endangerment in its habitats.

Efforts were made to conserve 570 accessions of wild edible fruit plants collected and conserved at JNTBGRI (Jawaharlal Nehru Tropical Botanic Garden and Research Institute) as part of the project entitled “Germplasm collection, evaluation of yield potential and exploitation of the fruit crops of the Western Ghats of Kerala”. The lesser- known wild plant accessions belongs to 106 species under 41 families. All the accessions are conserved ex-situ in JNTBGRI, Kerala, India. Among those 106 species, 67 species yield raw fruits, 11 species yield vegetable fruits, 22 species yield edible seeds / grains / kernels and the remaining 6 species yield spices and condiments. Twelve species are endemic to the Western Ghats region, of which, Salacia beddomei (Hippocrateaceae) comes in the red listed category and found mention in the Red Data Book of Indian Plants (Nayar & Sastry, 1988).

Salacia malabarica (Celastraceae), an important endemic climber of the southern Western Ghats is found very poor seedling bank in this natural habitats. This will lead to the untimely endangerment of the species in near future. The present study is therefore, aimed to develop and standardize the clonal propagation techniques through stem cuttings and air layering methods with the aid of auxins. The highest rooting of 90% was achieved with the use of NAA-1000 ppm from tender stem cuttings of 10-12 years old plant and air layering success was also found to be 80% by the use of NAA-1000 ppm from the same age of plants used for stem rooting.

The Western Ghats is a chain of mountains and is one of the 33 recognized ecologically sensitive zones in the world. There are several centres of plant endemism and species richness within the Western Ghats. Cullenia exarillata Robyns is a large evergreen tree in the mid-elevation evergreen forests which is endemic to Western Ghats. This tree acts as a hot bed of activity when in flower and functions as a keystone resource for several species of arboreal mammals, including the endangered primate Lion tailed macaque and Nilgiri langur. A preliminary attempt is carried out to regenerate and restore the populations of C.exarillata. Seed germination studies were performed and seeds were treated using 3 different pre-sowing treatments. Seeds were soaked in Dithane-45 for 5minutes, in cow dung extract for two nights and in gibberillic acid (100 ppm) for 24 hours. Untreated seeds were also used as control. Dithane-45 treatment showed 80% seed germination and the cow dung extract treatment showed 20% seed germination. Dithane-45 treatment promotes speedy seed germination when compared to other treatments. Therefore, pre-sowing treatment with Dithane-45 for 5 minutes was more effective for this plant.

Propagation by cuttings is an effective method for ex-situ conservation of plants. In the present study, propagation of Ginkgo biloba L. was conducted using hardwood and semi hard wood cuttings. The cuttings from basal part of the tree were selected for the experiment and planted during rainy (i.e. July) and summer season (i.e. April) at Central Department of Botany, T.U. Cuttings beds were prepared using 3:1 sand and soil. Different concentration of auxins such as IAA, NAA and IBA were found effective in inducing rooting. During July, the stem cuttings treated with 1000 ppm IAA for 30 minutes induced highest percentage (90 %) and statistically signifi cant (P< 0.05) rooting while those treated with same concentration and time induced only 40% rooting during April. Like wise other auxins NAA and IBA induced more rooting during July and less rooting during April. Cuttings planted as control, during July showed 10 % rooting while during April did not show any rooting. Among all the auxins studied, IAA hormone and rainy season was found to be the most effective for rooting of G. biloba cuttings. From the anatomical study it was revealed that vascular cambium, secondary phloem, cortical cells and pericycle cells took part on rooting. Successfully rooted cuttings were then transferred to the natural soil condition. J. Nat. Hist. Mus. Vol. 26, 2012: 175-180
