This experiment was conducted to evaluate the effect of seed priming on the germination and physiology of Pinus bungeana seeds. Seeds were treated by hydropriming with distilled water, halopriming with potassium nitrate （KNO3） at -0.3, -0.6, -1.2 MPa respectively （untreated dry seeds were taken as control）. Properties of seed germination and physiology were determined and the effect of hydro- and halopriming on germination and physiology ofP. bungeana seeds were investigated. The results showed that, compared with control, each priming treatment had increased the germination percentage （GP） and germination index （GI）, shortened the mean germination time （MGT） and the time required for 50% of the seeds to germinate （Gs0）. Primed P. bungeana seeds significantly decreased the relative conductivity and the amount of malondialdehyde （MDA）. Of all the treatments applied to seeds of P. bungeana, halopriming at -0.3 MPa KNO3 produced the highest GP （65.0%） and the shortest MGT （l 8.8 d） and Gs0 （18.2 d）.

Mitogen-activated protein kinases （MAPKs） are a family of Ser/Thr protein kinases widely conserved in all eukaryotes and involved in responses to biotic and abiotic stresses. In this study, two over-expressing BnMAPK1 oilseed rape lines, ov3 and ov11, were used to study the drought-resistant mechanism of BnMAPK1 under natural drought and simulation drought through spraying 10%PEG 8000 in seedlings. Zhongyou 821 （WT） was used as control. Compared with wild type, transgenic seedlings had higher leaf water content, higher root activity, slightly higher peroxidase （POD） and superoxide dismutase （SOD） activity, higher proline content and lower malondialdehyde （MDA） content. The expression of drought-resistant related genes, including P5CSB, PLC, LEA4 and SCE1, have been up-regulated in some degree and the expressed time of transgenic lines were earlier than that of wild type. These results suggested that over-expression of BnMAPK1 can enhance the resistance to drought in oilseed rape （Brassica napus）.

We set up computer vision system for tomato images. By using this system, the RGB value of tomato image was converted into HIS value whose H was used to acquire the color character of the surface of tomato. To use multilayer feed forward neural network with GA can finish automatic identification of tomato maturation. The results of experiment showed that the accuracy was up to 94%.

附随义务和缔约过失责任理论一直以来都被视为商业特许经营合同中特许人信息披露义务的法律理论基础,受此影响,商业特许经营合同订立中的信息披露义务也一直被定义为附随义务。但是这种定义方法忽视了商业特许经营合同独特的构造以及特许人和受许人之间特殊的结合关系,不仅损害了受许人的权益,更有悖于合同的公平和正义。因此,应当以协作义务为视角重新对商业特许经营合同订立中的信息披露义务进行考察,进一步明确特许人信息披露义务的具体内容,规范特许人的信息披露行为。特别是对于特许人的收益保证和推销辞令这两种颇具争议的信息披露行为,都可以从协作义务的角度赋予特许人特殊的披露规则,强化特许人信息披露义务的程度。同时,协作义务理论更为沉默性欺诈在商业特许经营合同中的适用提供了更为合理的理论基础。
