Allelopathic appraisal effects of straw extract wheat varieties on the growth of corn
Allelopathy is a process in which secondary metabolites produced by plants, micro-organisms, viruses and fungi control growth and development of other biological systems. Some plants may beneficially or antagonistically affect other plants through allelochemical compounds which may be released directly or indirectly from live or dead parts and cause allelopathic and phytotoxic effects. In Kerman province of...

Pathogenesis-related gene expressions in different maize genotypes under drought stressed conditions
Aflatoxins are carcinogenic compounds produced by Aspergillus flavus during infection of crops including maize (Zea mays L.). Contamination of maize with aflatoxin is exacerbated by late season drought stress. Previous studies have implicated numerous resistance-associated proteins (RAPs) that may be responsible for resistance to A. flavus colonization and aflatoxin accumulation. This...

The status and use of tree biomass in the tribal village ecosystem of Bolangir District, Orissa, India
The status of tree biomass resource was investigated in 3 tribal villages (Chikalbahal, Kudasingha and Bhutiyarbahal) of Bolangir District of western Orissa. There were 57 tree species with 12 tree capita-1 and 35 trees ha-1. Multiple benefits yielding local tree species dominated the village ecosystem, while fuel only or single end use trees accounted for a small proportion of trees. The standing tree...

Constituents of the essential oil from leaves and buds of clove (Syzigium caryophyllatum (L.) Alston)
Essential oil obtained by hydrodistillation from fresh leaves and dry buds ofSyzigium caryophyllatum were analyzed by Gas Chromatography Mass Spectrometry (GC-MS). Thirty eight components were identified in the leaf oil. The main components were eugenol (74.3%), eucalyptol (5.8%), caryophyllene (3.85%) and a-cadinol (2.43%). Thirty one components were identified in bud oil with the main components being...

Status of some species of rattans in the forests of the Western Ghats of Karnataka, India
The rattans of Peninsular India belong to only one genus namely Calamus and of the 21 species reported here, 20 are from the western Ghats Forests. Of these, the status of Calamus delessertianus and Calamus rheedei is uncertain and of the remaining 18 species 15 are endemic to the Western Ghats. Among the five states falling within the jurisdiction of the Western Ghats, Karnataka...

Correlation and path analysis for yield and yield contributing characters in wheat (Triticum aestivum L.)
Correlation coefficients were determined in fifteen wheat genotypes for plant height, days to heading, days to maturity, 1000-kernel weight, spike length, number of tillers per plant, number of spikelets per spike and grain yield per plant. The result revealed that grain yield per plant was positively and highly significantly correlated with days to maturity but negatively and highly significantly associated...
