Fifteen okra germplasm entries viz. accessions: IC0506027, IC0506118 and EC0306728; Abelmoschus spp.: Abelmoschus tuberculatus, Abelmoschus moschatus, Abelmoschus angulosus, Abelmoschus tetraphyllus, Abelmoschus manihot and Abelmoschus caillei; genotypes: POL-6 and POL-7; and four cultivated varieties: Punjab 8, Punjab Padmini, Punjab 7 and Pusa Sawani were screened against jassid, Amrasca biguttula biguttula (Ishida) in field at Vegetable Research Farm, Department of Vegetable Science, Punjab Agricultural University, Ludhiana, India during Kharif 2015. Different morphological and biochemical parameters of leaves of the selected entries were also studied. The correlation between jassid nymphal population and mid vein hair density, total phenols and tannins was negative and significant (r = ?0.67, ?0.83, ?0.75, respectively); negative and non-significant for hair length, angle of insertion of hair, total sugars and silica (r = ?0.40, ?0.49, ?0.63 and ?0.59, respectively) and positive and highly significant for lacination index, reducing sugars and lignins (r = 0.82, 0.95 and 0.90, respectively). Abelmoschus spp. Abelmoschus tetraphyllus, Abelmoschus angulosus and Abelmoschus moschatus were found to be field resistant on the basis of significantly lower pooled jassid nymphal population (1.56–1.99), jassid injury index (1.16–1.27) and susceptibility index (2.70–2.92). High degree of resistance in Abelmoschus tetraphyllus, Abelmoschus angulosus and Abelmoschus moschatus was found to be associated with high hair density (4.75–7.50), longer hair (1285.00–1513.20 μm), more erect hair (83.40–95.20°), broad leaves, high total sugars (15.21–18.36 mg/g), total phenols (1.52–1.58 mg/g), tannins (26.12–31.48 mg/g) and silica (32.66–33.17 mg/g) and low levels of reducing sugars (2.50–3.39 mg/g). Abelmoschus tuberculatus, A. manihot, IC0506027 and EC0306728 were found moderately field resistant with variable levels of morphological and biochemical parameters. High hair density, broad leaves, moderate levels of total sugars, reducing sugars, total phenols, tannins and silica seems to be associated with moderate levels of resistance in these entries. The variable levels of above mentioned parameters in moderately resistant entries also indicate that a single factor is not responsible for resistance but combination of different factors may be conferring resistance to jassid. 相似文献

Burning of rice straw is a common practice in northwest India, where rice–wheat cropping system is extensively followed. The practice results in loss of nutrients, atmospheric pollution and emission of greenhouse gases. A field experiment was conducted at Indian Agricultural Research Institute, New Delhi, India during the rabi season (November to April) of 2002–2003 to evaluate the efficacy of the various modes of rice straw recycling in soil in improving yield and soil fertility and reducing not only carbon dioxide emission but also nitrous oxide (N2O) emission. The treatment with no rice straw incorporation and application of recommended doses of fertilizer (120, 26 and 50 kg N, P and K ha−1, respectively), gave the highest yield of wheat. Treatments with the incorporation of rice straw at 5 Mg ha−1 with additional amount of inorganic N (60 kg N ha−1) or inoculation of microbial culture had similar grain yields to that of the treatment with no straw incorporation. The lowest yield was recorded in the plots where rice straw was incorporated in soil without additional inorganic N and with manure application. All the treatments with rice straw incorporation had larger soil organic C despite the effect on the mineralisation of soil organic matter. Emission of N2O was more when additional N was added with rice straw and secondary when straw was added to the soil because of higher microbial activity. The study showed that burning of rice straw could be avoided without affecting yield of wheat crop by incorporating rice straw in soil with an additional dose of inorganic N or microbial inoculation. However, the reduction of N2O emission due to avoiding burning is in part counterbalanced by an increase in emission during the subsequent wheat cultivation. 相似文献
