The growth rate of grass carp fed with hybrid napier was found to be nearly three times the growth attained with Hydrilla and about five times the growth attained with Ceratophyllum. The gross conversion ratio on fresh weight basis with hybrid napier was on average 26.99 : 1, while with Hydrilla and Ceratophyllum it was 93.98 : 1 and 128.43 : 1 respectively. The average net production of grass carp fed on hybrid napier worked out to 1579.3 kg/ha in 182 days. 相似文献

The synthetic 1-oxo-indanoyl-l-isoleucine methyl ester (Ind-Ile-Me) represents a highly active mimic of octadecanoic phytohormones, which are involved in plant defenses against pathogens and pests. Seed treatments and foliar spray with Ind-Ile-Me were tested for induced resistance against downy mildew disease caused by the phytopathogenic oomycete Sclerospora graminicola in pearl millet (Pennisetum glaucum) under greenhouse and field conditions. Under greenhouse conditions, a 50% protection level was achieved after seed treatment. Seed treatment in combination with foliar spray resulted in 60% protection. The induction of resistance was correlated with the enhanced activities of defense-related proteins such as phenylalanine-ammonia-lyase, peroxidase, and enhanced level of hydroxyproline-rich glycoproteins. Under field conditions, a maximum protection of 62% was recorded upon seed treatment along with foliar spray. Hence, it infers that Ind-Ile-Me can be used as a valuable protection compound at least in downy mildew disease management. 相似文献

The earliest step in creating the cerebral cortex is the specification of neuroepithelium to a cortical fate. Using mouse genetic mosaics and timed inactivations, we demonstrated that Lhx2 acts as a classic selector gene and essential intrinsic determinant of cortical identity. Lhx2 selector activity is restricted to an early critical period when stem cells comprise the cortical neuroepithelium, where it acts cell-autonomously to specify cortical identity and suppress alternative fates in a spatially dependent manner. Laterally, Lhx2 null cells adopt antihem identity, whereas medially they become cortical hem cells, which can induce and organize ectopic hippocampal fields. In addition to providing functional evidence for Lhx2 selector activity, these findings show that the cortical hem is a hippocampal organizer. 相似文献

The batch bioreduction of Cr(VI) by the cells of newly isolated chromium-resistant Acinetobacter sp. bacteria, immobilized on glass beads and Ca-alginate beads, was investigated. The rate of reduction and percentage reduction
of Cr(VI) decrease with the increase in initial Cr(VI) concentration, indicating the inhibitory effect of Cr(VI). Efficiency
of bioreduction can be improved by increasing the bioparticle loading or the initial biomass loading. Glass bioparticles have
shown better performance as compared to Ca-alginate bioparticles in terms of batch Cr(VI) reduction achieved and the rate
of reduction. Glass beads may be considered as better cell carrier particles for immobilization as compared to Ca-alginate
beads. Around 90% reduction of 80 ppm Cr(VI) could be achieved after 24 h with initial biomass loading of 14.6 mg on glass
beads. Artificial neural network-based models are developed for prediction of batch Cr(VI) bioreduction using the cells immobilized
on glass and Ca-alginate beads. 相似文献

In rice seedlings, the organochlorine insecticide hexachlorocyclohexane (HCH) and its four major isomers—α,β, γ, and δ—have been shown to elicit their phytotoxic action by interacting with indol-3-ylacetic acid (IAA)-regulated growth and Ca2+-ATPase activity. When rice seedlings were grown in the presence of 0.34 mM HCH, seedling vigour was reduced to 33% of the control. A similar effect was observed when seedlings were grown in the presence of the γ and δ isomers, but not with the α and δ isomers of HCH. This reduced vigour could be restored by treating the seedlings with 100 nM IAA, suggesting that HCH and its isomers (γ and δ) limit either IAA synthesis or action or both. In a microsomal fraction from rice seedlings grown in the presence of either HCH or its isomers, the calmodulin-regulated Ca2+-ATPase activity was inhibited as follows: technical HCH = 46%, α isomer = 80%, β isomer = 72%, γ isomer = 65% and δ isomer = 62% of the control value, respectively. TLC analysis suggested that the various isomers of HCH are metabolised by the plant, except for the δ isotner, which accumulated. This isomer, along with the degraded products of other isomers, may be responsible for the phytotoxic action of HCH. 相似文献

In an attempt to find a suitable alternative to the otherwise perilous chemical control strategy of disease management, the
amino acid proline was evaluated for its efficiency to elicit resistance in pearl millet (Pennisetum glaucum (L.) R. Br.) against downy mildew disease caused bySclerospora graminicola (Sacc.) Schroet both under greenhouse and field conditions. Proline treatment to seeds at 50 mM concentration for 3 h, significantly
enhanced the seed germination and seedling vigor of pearl millet in comparison with the control. The same concentration and
duration of seed treatment protected the pearl millet plants from downy mildew by offering 58% protection under greenhouse
and 67% protection under field conditions. Studies revealed that 3 days were required for proline-treated plants to develop
resistance, which was systemic and was sustained throughout the life of the plants. Apart from disease protection, proline
was also found effective in enhancing vegetative and reproductive growth of the plants, as evidenced by the increase in height,
fresh weight, leaf area, tillering capacity, 1000-seed weight and grain yield in comparison with the control plants.
