Various concentrations of 42 dyes, alkaloids, plant-growth regulators, and miscellaneous chemicals were tested as substitutes for rose bengal in peptone–dextrose–streptomycin agar for isolating soil fungi by the dilution-plate method. Most of the chemicals did not compare favorably with rose bengal, but a plant growth retardant 2,4-dichlorobenzyltributylphosfonium chloride (phosfon) used at 500 μg/ml significantly increased numbers of fungal colonies per plate and suppressed fast-growing fungi. The value of phosfon persisted even in the presence of gibrel, which alone induced rapid overgrowth of plates by Trichoderma and the Mucoraceae.

An experiment was conducted with different concentrations of plant growth regulators to evaluate their effects on the growth and yield of late planted Mukhi Kachu (Colocsis esculenta). Different treatments of uniconazole (growth retardant showed significant influence on plant height, petiole length, number of leases per plant, weight of leaf and weight of petioles per hill, number and weight of corms and cormels per hill and yield of cormel.

Reclamation Process

In order to know the effect of vegetation and fertilizer on the occurrence of soil fungi, a study was conducted in reclamated gold mining land both in Cimanggu and Bojong Pari, Jampang, Sukabumi. Soil fungi were isolated by dilution plate method, using a tauge sucrose agar? medium with 50 ppm antibiotic and incubated at room temperature for 2-3 days. Fungi identification follows Domsch et al (1980), Samson et al (1981), and Barnet (1969). The effect of vegetation and fertilizer on the composition of soil fungi in reclamated land both Cimanggu and Bojong Pari were not quite different. Aspergillys, Eupenicillium, and Pennicillium maybe dominant fungi in these areas. These fungi were probably involved in reclamation of land. To obtain faster reclamation process, the fungi are better involved as one of introduced microorganism besides Rhizobium and Mychorizal fungi or mixed inoculants. Besides election of suitable flora and fauna, soil fungi are expected to be able recover degraded land into original ecosystem.

Experimental Model System

The influence of 24-epibrassinolide on the efficiency of regenerants obtained from embryonic calli formation was studied in wheat cultivars contrast for drought resistance. The possibility of using the experimental model system «immature embryo – embryonic callus – regenerant» in the rapid assessment of the effect of antistress plant growth regulators is shown.

Appreciable Variation

The influence of stage of fruit development and plant growth regulators on somatic embryogenesis and the relation of cultivar response on somatic embryogenesis and subsequent plant development have been investigated in eight cultivars of pecan [Carya illinoensis (Wangenh.) C. Koch]. Explants from the micropylar region of the ovule were more embryogenic when removed from fruits in the liquid endosperm stage than were intact ovules from less-mature fruits or from cotyledonary segments of more-mature fruits. Explants conditioned on medium containing auxin alone or auxin + cytokinin produced more somatic embryos than medium containing cytokinin alone. Under the conditions of this study, frequency of embryogenesis, as well as the germination of somatic embryos leading to plant development, indicated appreciable variation among cultivars. Plant development was greatest by far from somatic embryos of `Schley' than other cultivars studied.
