A rice yellow-green mutant (HY 101) was segregated from an H2 strain of a pollen plant which was produced from the cultured anthers of the variety 8126 treated with mutagen EMS at the early stage of culture.The mutant plants are yellow-green color and the chlorophyll content of its leaves is only about one third of that of normal leaves.The mutant characters are more stable and not a single green plant was observed in the following four generations and in plantlets from mutant by anther culture.The F,plants of hyprids between the mutant and normal plants,whether it is used as maternal or paternal parent,were all normal green.The segregation ratio of green plants to yellow-green plants was 3:1 in F2 hybrid plants and 1:1 in pollen plantlets from F1 hybrid plants by anther culture.Thus,the mutant characters are attributed to a single recessive gene located in nucleus.

用甲基磺酸乙酯(EMS)处理粳稻品种8126离体培养早期的花药,从所产生的一个花粉植株的H,株系中分离到一个黄绿色突变体。突变体植株叶片的叶绿素含量仅为正常叶片的1/3。突变性状稳定,在连续自交4代中,没有出现任何绿色植株;由突变体通过花药培养产生的植株除部分白化苗外均呈黄绿色。突变体与正常植株杂交,无论其为父本或母本,杂种F_1均为绿色植株;杂种F_2分离的绿色与黄绿色植株数比值符合3:1;由杂种F_1植株通过花药培养产生的小苗中绿苗与黄绿苗数的比值符合1:1。证明突变性状是由单一的隐性细胞核基因所控制。

This paper concerns the photosynthetic characteristics of a yellow-green nucleus mutant ofricewhich was obtained in anther culture by us. The content of total chlorophyll, xanthophyll and β-carotene in the mutant leaves is about 31%, 40% and 75% of that in normal leaves respectively; the chl a/chl b ratio of the mutant is much higher than that of normal leaves. The analysis of SDS-solubilized extracts of the chloroptast lamellae shows that the major light-harvesting chl a/b protein complex of the mutant is extremely...

This paper concerns the photosynthetic characteristics of a yellow-green nucleus mutant ofricewhich was obtained in anther culture by us. The content of total chlorophyll, xanthophyll and β-carotene in the mutant leaves is about 31%, 40% and 75% of that in normal leaves respectively; the chl a/chl b ratio of the mutant is much higher than that of normal leaves. The analysis of SDS-solubilized extracts of the chloroptast lamellae shows that the major light-harvesting chl a/b protein complex of the mutant is extremely dciicicnt, and its chl a/chl b ratio is more than 3. In the chloroplasts of mutant leaves, there are very few grana stacking, and more starch grains can be seen when leaves are exposed to sun light. The rate of CO2 assimilation of mutant leaves exposed to 20000 lux of sun light is 75% of that of normal leaves on a basis of leaf area, and is 185% on a basis of chlorophyll. The chloroplasts of the mutant may also show a much higher rate of ferricyanide Hill reaction on a basis of chloropyll.The results show that the grana stacking of chloroplast is closely related to the quantity of the light-harvesting chl a/b protein, and is not essential for photosynthesis process.

本文报道一个黄绿色水稻突变体光合器官结构和功能的某些特点,该突变体是作者通过花药培养得到的细胞核突变体。突变体叶片的叶绿素含量、叶黄素和β-胡萝卜素含量分别约为正常叶片的30%、40%和75%;chl a/chl b比值显著高于正常叶片。对SDS增溶的叶绿体片层叶绿素蛋白质复合物分析表明,突变体的捕光chl a/chl b蛋白质复合物极度减少,该复合物的chl a/chl b比值大于3。突变体的叶绿体明显缺乏基粒堆积,在日光下容易较快积累淀粉粒。突变体的叶绿体悬液有较高的铁氰化钾光还原活性。在2万lux日照强度下,突变体叶片同化二氧化碳的速率,以单位叶面积计算为正常叶片的75%,以单位叶绿素计算为正常叶片的185%。结果证明,叶绿体基粒结构与捕光chl a/b蛋白质含量正相关,它并非为光合作用基本过程的进行所必需。

Field survey and spectro chemical analysis were conducted on eleven garden soils from southern Lioning province to study the amount of microelements of leaves or fruits and disease of apple trees.Results showed the following three conclusions;1.The amount of microelements-B.Fe.Mn.Zn and Cu in the experimental garden soils was different.Soil developed from shale was richer in microelements than that of granite or loess.2.Apple trees with fruit-curl disease usually showed lower boron content both in leaves and...

Field survey and spectro chemical analysis were conducted on eleven garden soils from southern Lioning province to study the amount of microelements of leaves or fruits and disease of apple trees.Results showed the following three conclusions;1.The amount of microelements-B.Fe.Mn.Zn and Cu in the experimental garden soils was different.Soil developed from shale was richer in microelements than that of granite or loess.2.Apple trees with fruit-curl disease usually showed lower boron content both in leaves and fruits.The ratio of boron in normal trees to diseased trees was 1.3-2.4:1 in leaves and 2.0-3.9:1 in fruits respectively.3.Leaf chlorosis of apple trees showed lower sontent of Fe and Mn,pa-rtically Mn content in leaves.Thus the ratio of Fe/Mn of leaves with chlorosis was higher then that of normal leaves.

为了研究苹果树叶片、果实的微量元素含量与苹果树病害的关系,作者对辽南地区十一个果园的土壤进行了野外调查和光谱化学分析,得到以下三点结论: 1.在所调查的果园土壤中,微量元素—B、Fe、Mn、Zn和Cu的含量是各不同的,发育于页岩上的土壤,其微量元素含量比发育在花冈岩或黄土上的富裕。 2.有缩果病的苹果树,其叶片和果实中的硼含量一般较低,正常树和有缩果病树之间硼的比值,在叶片和果实中分别为1.3~2.4:1和2.0~3.9:1。 3.有黄叶病的苹果树,Fe和Mn含量较低,特别是叶片中的Mn含量更低。因此有黄叶病的叶片中的Fe/Mn比值较正常树叶片高。
