The highest value of photosynthetic rate and active photosynthesis duration in flag leaves could be increased in a range of 3.55% and 3 d by dressing N (112.5 kg/ha) at heading stage in hybrid rice variety cv. Shanyou63 compared with control (no dressing N at heading), respectively. This resulted in the 7.93 percentage and 5.70 percentage increases of its leaf source capacity (LSC) and yield, respectively. Furthermore, genetic analysis of LSC was made by 4 × 4 incomplete diallel cross-design with 4 sterility lines and 4 resilience lines. The results showed that hB2 and hN2 in LSC for rice were higher than 70 percentage and 30 percentage, respectively, suggesting that it may be used as an index for selecting varieties with high photosynthetic efficiency in rice breeding. There were the similar effects of the additive and non-additive variations on LSC in hybrid rice. LSC was mainly influenced by sterility line and resilience interactions. The adding effect value of general combining ability for its parents may be used to forecast the phenotype of LSC in hybrid rice.

It is well known that large-capacity wind power, as a type of strong fluctuations and random power, has an impact on grid safety. Due to this situation, accurate wind speed forecast plays an important role in reducing the impact of wind power on the grid. In this paper, we discuss the short-term wind speed forecast problem based on the wavelet packet transform and least squares support vector machine （LS-SVM）. Firstly, high-frequency and low-frequency signals of wind speed are analyzed by the wavelet packet algorithm. Then, optimal wavelet packet transform is selected by minimum entropy principle. Based on these, short-term wind speed forecast model is established by LS-SVM. As an application of the proposed method, a case study with the actual data of a wind farm is presented to show the efficiency and accuracy compared with the previous results.
