The method of propagation of wild cardamons in evergreen forests, and the technique of raising new plantations in suitable areas are described with figures of cost and yield. Hints on collection, curing and storage with a description and sketch of a cardamom drying kiln are given.

Cytomorphological characteristics of Indian hexaploid S. nigrum and S. nodiflorum and of their F1hybrids were studied. The parents differed significantly in several morphological and cytological characters. The hybrids were highly sterile and did not set seed.They showed a wide range of meiotic irregularities. In several pollen mother cells, trivalents and quadrivalents were recorded, although in a very low frequency, in addition to a large number of univalents and bivalents. Occasionally bridges with or without fragments, were recorded. The results of these investigations show that chromosomal differences as well as genic differences have played an important role in reproductive isolation and morphological differentiation of the two species.

Biosystematic studies have been carried out on some species of the Solanum nigrum complex, viz., diploid S. nigrum, S. nadiflorum, tetraploid S. nigrum, S. luteum and S. villosum. A comparison of fruit colour and chromosome number of the taxa divides them into two groups. Diploid S. nigrum and S. nodiflorum have shiny bluish black fruits and n = 12 chromosomes. In tetraploid S. nigrum the fruits are orange red while in S. luteum and S. villosum the fruits are yellow and the chromosome number in all the three taxa is n = 24. Meiosis was normal in all the species. The close relationship between diploid S. nigrum and S. nodiflorum, and among the species tetraploid S. nigrum, S. luteumand villosum has been confirmed by cytogenetical studies and statistical comparison of mean values of morphological characters.In the light of the foregoing studies a taxonomic revision of the species studied is suggested.

Indian Welding Journal, Vol 7, No 1 (1975), Pagination: 10-13Abstract
Welded construction represents a creative endeavour comprising of two phases, conceptual and implementary. Concept, however brilliant, without the means for its implementation will remain only a dream. Implementary art in the form of welding technology and behavioural analysis has amply proven the adequacy for realization of many a fine concept in welded design. It now stands as a challenge to all potential users of welding technology in structural fabrication, stimulating their imagination in the process of expressing their daring and creative thoughts. Castellated beams will be the motive force for such expression.- Some Aquatic Macrophytes and their Metal Accumulation Potentiality

The present study analyses the potential capacity of aquatic macrophytes to accumulate heavy metals from contaminated waters of three different aquatic bodies namely Mahil Talab, Sumera Talab and Kothi Talab (lake). Four different macrophytes taken for study due to their abundance, are named as Eichhornia crassipes (Mart.), Hydrilla verticillata (L. F.), Chara spp. (L.) and Lemna minor (L.) Samples for the analysis of heavy metals were collected from these ponds during the period of October 2015 to September 2016. Five heavy metals named as Fe, Cd, Cu, Cr, Pb and Ni were analyzed in water, sediments and selected plant species which were abundant in water. The amount of metals and their accumulation status recorded in the studied macrophytes are arranged in the given sequence Fe>Pb>Cd>Cr>Cu>Ni. On the basis of metal concentration in different aquatic plants, water bodies and sediment, Pb and Cd was found to be target metal for the removal from the selected water bodies. The present experiments were carried out in the laboratory to analyze the Pb and Cd uptake capacity by above mentioned aquatic macrophytes. From the aspect of phytoremediation in present research, out of the four different macrophytes as above E. crassipes and Chara spp. may be considered as more affective for remediation of contaminated water bodies of Bundelkhand region especially for Pb and Cd removal.Keywords
