Studies on Coleus Starch

Abstract: Coleus starch was isolated by standard procedure and its properties studied. The granule size varies from 5 to 20 μm with majority being in the range 8–16 μm. The gelatinization temperature is 65–85°C. Viscosity of a 2% solution is 37 s (Redwood No. 1). The viscosity increases to 56 s on cooling and remains steady afterwards. The sol stability of the 2% solution is 72 h. The total amylose content is 33% of which soluble amylose is 12.8%. The sweeling volume is 25 cm3/g of starch the reducing value in terms of ferricyanide number is 2.71. The results are discussed in comparison with other tuber starches.

Weed control approaches for tropical tuber crops - A review

Abstract: In tropical tuber crop production the crop initial slow growth can be outpaced by weeds. Weed control consumes about 30% of total labor input (approximately Rs. 102,000 million). Draught animals us...

Effects of microbial inoculations on soil chemical, biochemical and microbial biomass carbon of cassava (Manihot esculenta Crantz) growing Vertisols

Abstract: Cassava is an important subsidiary food in the tropics. In Tamil Nadu, India, microbial cultures were used to eradicate the tuberous root rot of cassava. Hence, an experiment was conducted for two consecutive years to test the effects of coinoculation of microbes on soil properties. The surface soil from the experimental site was analysed for soil available nutrients, soil enzyme activities and microbial biomass carbon. The treatment of Azospirillum with Trichoderma at the 50% recommended N:P2O5:K2O (NPK) rate (50:25:50 kg ha−1) significantly increased soil available nitrogen (142.81 kg ha−1) by 72.66% over uninoculated control. There was a significant increase in available phosphorus in soil by the inoculation of AM (arbuscular mycorrhizal) fungi with Trichoderma at the 50% recommended NPK rate (41.04 kg ha−1) compared to other treatments. The application of Pseudomonas fluorescens with Trichoderma at the 50% recommended NPK rate significantly increased available iron (19.34 µg g−1) in soil. The treatmen...

The pachytene chromosomes of Ipomoea crassicaulis

Abstract: The detailed morphology of the pachytene chromosomes and microsporogenesis have been studied in a diploid (2 n=30) American species, Ipomoea crassicaulis (Bth) B. L. Robinson. Idiogram of the pachytene chromosomes is presented and taking advantage of the extreme precision that pachytene analysis can lend, karyological characteristics of the haploid complement have been worked out in detail and individual chromosomes are identified. The course of meiosis was normal and over ninety five percent of pollen were found stainable. The urgent need for extending similar studies to other taxa in this economically important genus for unravelling phyletic relationships has been stressed.
