Abstract

In this paper, a small hydropower microgrid solution with high applicability is proposed to solve the problem of high line failure rate and long maintenance time, which can improve the reliability of distribution network in mountainous areas. In this scheme, small hydropower and local load constitute a low-cost but efficient microgrid operation to improve the reliability of rural electricity. In this scheme, small-sized hydropower and local load constitute microgrid operation. In case of failure, the scheme makes full use of the independent operation of microgrid to provide qualified power quality to local load. This scheme is easy to realize and does not need additional energy storage, so it has good economy. Firstly, the frequency disturbance characteristics of small hydropower microgrid is analyzed, which lays a theoretical foundation for small hydropower microgrid operation. Then it introduces the island operation mode to grid-connected operation mode transition of small hydropower, including the key technologies such as frequency adjustment strategy in island operation stage. Finally, the simulation studies show the effectiveness of the method.

Abstract

‘Red Fuji’ apple (Malus × domestica Borkh.) scions were grafted onto eight size-controlling rootstock combinations (dwarfing, semi-dwarfing, and vigorous types). During the third year after grafting, morphological and physiological parameters, such as growth, hydraulic conductance, non-structural carbohydrates, gas exchange and chlorophyll fluorescence, as well as leaf anatomy, were examined and instantaneous whole-canopy photosynthetic assimilation was modelled. Compared with Baleng, rootstocks M.9 and B.9 resulted in reduced growth vigour and photosynthetic capacity. Significantly lower soil-to-leaf hydraulic conductance, stomatal density and palisade/spongy parenchyma ratios were also observed in ‘Red Fuji’ grafted on M.9 and B.9. We propose that the down-regulated hydraulic conductance contributed to the decline in photosynthetic rate, which in turn caused a reduction in instantaneous whole-canopy photosynthetic assimilation. These results provide evidence that the limited photosynthetic capacity and leaf area are major causes of the reduced canopy photosynthetic assimilation observed in M.9 and B.9 grafted apple trees. The reduced photosynthetic assimilation may partly result from a sustained lower photochemical efficiency. However, dwarfing and semi-dwarfing rootstocks grafted plants contained more starch, which may be a significant factor underlying the observed advanced precocity.

Abstract

Cucumber is one of the most important vegetables that are very sensitive to low-light stress. The specific mechanism involved is poorly understood. Here we investigate the expression profile of genes induced by low-light stress in Cucumis sativus seedlings with suppression subtractive hybridization (SSH). cDNA prepared from cucumber seedlings treated with 100 μmol m −2 s −1 light intensity as testers and cDNA from unstressed cucumber seedlings with 800 μmol m −2 s −1 light intensity as drivers. A forward subtractive cDNA library was constructed, from which 768 recombinant colonies were picked and amplified. Through differential screening of the subtractive cDNA library, 246 clones were identified as low-light stress induced. After sequencing, 64 unique expressed sequence tags (ESTs) were obtained by clustering and blast analysis, which included some functionally unknown transcripts. Of the 64 ESTs, 50 ESTs identity to their homolog in GenBank, 14 ESTs were expected to be novel genes. The ESTs with significant protein homology were sorted into 16 groups according to the functional categories of the Arabidopsis proteins.
