As to'Cabemet Sauvignon'and'Queen of Vineyard', which belong to the'West Europe Cultivars Group', no obvious decline of Fv/Fm was found in their potted plants even under severe drought stress. Their photosynthetic abilities also greatly recovered after rewatering, i. e. no serious photodamage was formed in these cultivars under drought stress. Between them, the φPSⅡ of 'Queen of Vineyard'under severe drought stress was much lower than that of'Cabernet Sauvignon', which suggested that the light use efficiency of the former was much lower than the latter under severe drought stress. The potted plants of'Autumn Royal'and'Rizamat' sustained high Fv/Fm and φPSⅡ before moderate drought stress, but seriously declined under severe drought stress, which indicated that these cultivars had a weak resistant ability to extreme drought stress. A hybridized cultivar of Vitis vinifera L. and V. labrusca L.,'Red Double Taste', its Fv/Fm and φPSⅡ expressed mild decline along drought stress grade.φPSⅡ of'Red Double Taste'was the highest among seven cultivars under severe drought stress condition, which might closely connected with its high photorespiration activity. Another new cultivar,'Red Globe', and a rootstock,'1103Paulsen', the Fv/Fm and φPSⅡ of their potted plants declined markedly under slight drought stress, which suggested that they held a weak ability to defend against photoinhibition.

西欧品种群的赤霞珠和葡萄园皇后，其盆栽苗的Fv／Fm直到重度干旱胁迫下仍没有明显的降低，且复水后光合能力恢复程度较高，即干旱没有给这两个品种造成严重的光破坏，而两个品种之间，葡萄园皇后在重度干旱胁迫下的φPSⅡ明显低于赤霞珠，说明其光合器官在严重干旱胁迫时对光能的利用率较差；新品种皇家秋天和东方品种群的里扎马特在中度干旱胁迫下仍可维持较高的Fv／Fm和φPSⅡ，但在重度干旱胁迫下则降低幅度较大，说明其抵御极端干旱胁迫的能力较差；欧美杂种红双味的Fv／Fm和φPSⅡ随着干旱胁迫程度的增加呈现平缓的下降趋势，而且其φPSⅡ在重度干旱胁迫下是七个品种中最高的，这应该与其此时仍维持较强的光呼吸活性有关；红地球和砧木1103Paulsen的Fv／Fm和φPSⅡ在轻度干旱胁迫下就明显下降，表明干旱条件下其抵御光抑制的能力较差。

Ten years wide investigation and research on the characteristics and pathogenicity of cryphonectria parasitica showed that, Cryphonectria parasitica existed widely in the distributing areas of Castanea mollissima, and that it belonged to weak parasite, only lived on the weak and dying branchs, sprouts, and soon. Cryphonectria parasitica was not main and direct death cause of Castanea mollissima, and the dead parts had no great influence on the growth of whole tree.

经过10余年对栗疫病发生特点和致病性的大量调查研究，结果表明栗疫菌在板栗分布区普遍存在，是弱寄生菌，在本地只寄生那些生长十分衰弱，即将死亡的板栗树干、苗木等，但栗疫菌的寄生不是这些部位死亡的主要和直接原因，而且它所寄生的部位局部死亡后对整株栗树的影响不大，因此，栗疫病在一般倩况下并非毁灭性病害。

Therelationship between the turbulent kinetic energy and its dissipation rate,whichis widely used to parameterize the dissipation rate in turbulence closure models,is found to hold well for both reversing and rotating flows,but with differentcoefficients.Microstructure profiling measurements at two comparative stations (a deepercentral basin and a local shelf break) in the stratified Yellow Sea are analyzed,with emphasis on tidal and internal-wave induced turbulence near the bottomand in the pyenocline.The water column has a distinct three-layer thermohaline structure,consisting of weakly stratified surface and bottom boundary layers anda narrow sharp pycnocline.Turbulence in the surface layer is controlled by thediurnal cycle of buoyancy flux and wind forcing at the sea surface.while thebottom stress induced by barotropic tidal eurrents dominates turbulence in thebottom boundary layer.The maximum level at which the tidally enhanced mixingcan affect generally depends on the magnitude of the tidal current,and it canbe up to 10-15 m in the Yellow Sea.This suggests that,in the deeper regionsof the shelf seas,turbulent dissipation and mixing are very weak at the levelsbetween the near-bottom tidally enhanced layer and the pycnocline.Therefore,these levels provide a significant bottle neck for the vertical exchanges.In theshallow regions,however,the tidally-induced turbulence can occupy the wholewater colum below the pycnocline.A quarter-diurnal periodicities of the turbulentdissipation rate and eddy diffusivity are found at different heights with evidenttime lag.In the relatively flat central basin,the pycnocline is essentially non-turbulent and internal-wave activity is very weak.Therefore,vertical fluxes acrossthe pycnocline decreased to molecular levels.In contrast,internal waves of variousperiods can be always found near the local shelf break.

对强层化季节黄海两对比性站位(分别位于中央海盆区与局地陆坡区)处层化、内波以及湍流混合特征的研究结果表明：1、强层化季节的陆架海水体一般呈现显著的三层热盐结构，在水体近乎混合均匀的上混合层与潮流底边界层之间为强跃层；2、近表层水体的湍流混合强度主要由海表浮力通量的日变化与海表风强迫控制，而在潮流底边界层内，潮混合是水体热量、物质、动量与能量垂直交换的主要机制；3、潮混合影响的深度由潮流大小决定，在黄海，一般可达10-15 m，因此，在水深较深的区域，在跃层与潮混合所至深度范围的上界之间存在湍流混合非常弱的区域，这显著抑制水体内物质的垂直通量，为物质垂直交换的瓶颈，而在水深较浅的区域，潮混合影响范围可至跃层底部，因此物质在跃层以下整个水体中混合非常均匀，当跃层内间歇性强混合发生时，可以产生显著的跨跃层物质输运；4、近底潮致强湍流耗散缓慢地向上传播，底上不同深度处垂直湍扩散系数也具有显著的位相差异，且二者均随时间呈现四分之一周日周期的变化；5、在地形较为平坦的中央海盆区，内波活动非常微弱，因此跃层内湍流混合非常弱，垂直扩散系数为分子扩散水平，跨跃层物质通量受到显著抑制，而在地形变化较为显著的局地陆坡区，内波活动非常活跃，除内潮的影响外，高频内波与内孤立波的影响也很显著，因此跃层内存在很强的间歇性强混合，内孤立波存在的区域，水体湍流混合显著增强。
