Relationships between D1 protein, xanthophyll cycle and photodamage-resistant capacity in rice (Orysa sativa L.)

Relationships between D1 protein, xanthophyll cycle and subspecific difference of photodamage-resistant capacity have been studied in O. japonica rice varieties 02428 and 029 (photoinhibition-tolerance) and O. indica rice varieties 3037 and Palghar (photoinhibition-sensitivity) and their reciprocal cross F1 hybrids after photoinhibitory treatment. It was shown that PSⅡ photochemical efficiency (Fv /Fm) decreased, and xanthophyll cycle from violaxanthin (V), via anaxanthin (A), to zeaxanthin (Z) was enhanced and non-photochemical quenching (qN) increased accordingly in SM-pretreated leaves of rice when the synthesis of D1 protein was inhibited, and that there was a decrease in qN and, as a result, more loss of D1 protein and a big decrease in Fv /Fm in DTT-pretreated leaves when xanthophyll cycle was inhibited. O. japonica subspecies had a higher maintaining capacity of D1 protein and a decrease of Fv /Fm in a more narrow range, and exhibited more resistance against photodamage, as compared with O. indica subspecies. The above physiological indexes in reciprocal cross F1 hybrids, though between the values of their parents, were closer to maternal lines than to paternal lines. Experimental results support the concept that the turnover capacity for D1 protein is an important physiological basis of photoinhibition-tolerance, and will provide the physiological basis for selection of the photoinhibition-tolerant parents and develop a new approach to breed hybrids with high photosynthetic efficiency.     

不同杉木母树及球果对后代遗传品质影响的研究

本文通过对不同杉木母树及球果对后代遗传品质影响的研究，结果表明，不同母树间不管是大果型、中果型、小果型球果或种子千粒重的大小，其苗期生长（苗高、地径）和幼林生长（树高、胸径）遗传品质差异都不显著，故在杉木母树或杉木优树选择时，不能以球果及种子大小而决定取舍，说明不同母树或其不同家系其后代遗传并不受球果或种子大小的约束，而是该家系遗传基因决定的．不同杉木母树或家系，其遗传品质主要取决于基因和环境因素共同作用的结果。

多节状SiC晶须的合成及在矿冶工程材料中的应用

运用TEM、XRD等分析检测技术对SiCw的形貌结构、长度与直径分布及其应用于复合材料中的特性进行了检测。研究表明：SiCw产品以直晶为主，表面呈多节状，以-SiC为主要晶型，直径为0.2～1.5m,长度为30～200m。此外，作者对SiCw在矿冶工程材料中的应用进行了展望。     

水稻雄性不育细胞组织学的研究

水稻雄性不育系的花粉败育一般可分为无花粉型、单核败育型、双核败育型和三核败育型等四种。个别不育系花粉败育方式较特殊。野败不育系的花丝和药隔维管束退化最严重,花药开裂结构的异常主要表现在裂口、裂腔分化发育异常。     

Epicatechin can cause the seedling growth inhibitor,nagilactone E,to induce growth stimulation

Summary A possible new role for the flavonoid (–)-epicatechin (II) is described. It has no growth effects on its own, but when it is added to lettuce and rice seeds together with the known seedling growth inhibitor nagilactone E (I), the growth inhibitor activity ofI can cease and growth stimulation can be observed.     

Chemical composition and antioxidant activity of essential oil from Magnolia grandiflora L. seed

The chemical composition and antioxidant activity of Magnolia grandiflora L.seed essential oil were examined.By combining gas chromatography and mass spectrometry (GC-MS),16 types of compounds were identified,including 40.91% oxygen-containing terpene derivatives,19.51% terpenes,13.97% esters,13.05% nitrogenous compounds,and 3.64% acids.Its capability of removing hydroxyl free radical was lower than that of V c,but it was closer to V c with increasing concentration.In cell experiment,all essential oil concentration (6.9,13.8,27.7,55.5,111.0,and 222.0 g/mL) groups increased cell proliferation by 26% or more (26.0%,38.8%,44.8%,40.2%,35.8%,and 30.4%,respectively).In rat experiment,the SD rats group showed an at least 38% rise (38.62%,61.68%,and 62.86%,respectively) in glutathione-peroxisome (GSH-Px)activity,which is more than 24% reduction (29.56%,24.30%,and 36.93%) in malondialdehyde (MDA) content,and no significant difference in SOD activity was found.The results show that the essential oil had strong antioxidant activity,without dose effect within the concentration range.     

“黑麦草-水稻”草田轮作系统的根际效应Ⅰ.接种稻田土壤微生物对黑麦草生长和氮素营养的影响

研究在水田冬种黑麦草（Ｌｏｌｉｕｍｍｕｌｔｉｆｌｏｒｕｍ）对后作水稻的作用机理，通过水培试验，探讨了接种和不接种南亚热带稻田土壤微生物条件下黑麦草品种樱早生和早生丰的生长发育和氮素营养．结果表明，稻田土壤微生物参与并促进了黑麦草的物质生产过程，证明了在冬闲水田栽培黑麦草使后作水稻增产的现象与黑麦草的根际活性是有关的     

晚稻改种大豆的节水效能分析

该文通过对晚稻和大豆的自然供水条件分析表明：大豆比晚稻具有更明显的节水效能，江西省某些干旱严重的地区可以在伏秋季节改晚稻种植为大豆种植，这样可取得较好的经济效益。
