A vegetation survey based on releve analysis was conducted in Murree Hills
and Galliyats during autumn 1998 and spring 1999. The area was demarcated into
eight stands in which various phytosociological parameters were recorded. During
the tabulation of raw data, emphasis was laid upon the physical characteristics
of the stands. Composite soil samples were collected to find out pH, organic
matter, N, P, K, Ca++, Mg++ and textural classes. Plant
associations were identified based on chi-square analysis (including Yate`s
correction) and dominance of plants were based on highest importance values.
Urtica dioica and Rumex nepalensis were having similar
ecological amplitude and comprising an association among all stands. Mycorrhizal
association supported the distribution pattern of both the species. Rumex
nepalensis exhibited a healthy symbiotic association and was more mycorrhizal
as compared to Urtica dioica. The soil where phosphorus contents were
relatively lesser, a high degree of root length colonization by VAM fungi was
observed. The give and take role of this association proved by arbuscular infection,
which was intensely observed in the roots of Rumex nepalensis. In conclusion,
it seems that climatic conditions are utilized by both the species in more or
less similar way however, the dominance of Rumex nepalensis is a sign
of better exploitation of soil nutrients aided by mycorrhizal fungi. |

During germination, cultivar Monoval tolerated the salinity as well as higher temperature better as compared to Majoral, Monored and Polygroeningia cultivars of fodderbeet (Beta vulgaris). Whereas, cultivar Majoral had the lowest salinity and temperature tolerance during germination. The number of leaves, leaf length and root girth was not affected in cvs. Monoval and Monored under same soil conditions. Fresh weight of leaves and beet in cv. Majoral increased significantly over control. Chlorophyll a and chlorophyll b in cv. Majoral increased significantly. Total protein of leaf and sugar content of beet were comparatively higher under saline conditions as compared to the non-saline soil. |

Out of five biocontrol agents/antagonistic microbes viz., Verticillium lecanii, Paecilomyces fumosoroseus, Beauveria bassiana, Cladosporium cladosporiodes and Metarrhizium anisopliae, Beauveria bassiana proved the best in retarding the postulation/rust development in wheats. When the microbes tested alone against leaf rust development, B. bassiana proved excellent and in combination with Verticillium lecanii and Paecilomyces furnosoroseus. Although there was an increase in colony diameter after 2nd week but the pattern of growth was the same as after one week of incubation of bio-control agents application. |
