【目的】探讨糖酸组分在苹果杂交后代中的遗传规律。【方法】以苹果品种‘红玉’与‘金冠’及其杂交后代的实生群体为试材,利用高效液相色谱方法(HPLC),测定‘红玉’与‘金冠’及其杂交后代果实糖酸组分含量。【结果】糖组分含量在‘红玉’与‘金冠’杂交后代中呈正态分布,符合数量性状的遗传特点。在亲本与其杂交后代果实中,果糖、葡萄糖、蔗糖是主要糖组分。亲本的果糖与葡萄糖含量比例要低于杂交后代中2者的平均比例。杂交后代群体果实中果糖、葡萄糖、蔗糖平均质量分数分别为39.86、15.46、23.02 mg·g^(-1),遗传传递力分别为71.59%、65.56%、182.55%;果糖、葡萄糖的遗传主要是加性效应引起的,蔗糖的遗传除存在加性效应外,还存在一定程度的非加性效应。果实中酸的主要成分有苹果酸、枸橼酸、琥珀酸和草酸,草酸、琥珀酸、枸橼酸含量都呈不连续变异,苹果酸呈连续变异,具有典型的数量性状遗传特征。杂交后代群体果实中苹果酸、枸橼酸、琥珀酸、草酸平均质量分数分别为0.55、0.04、0.03、0.02 mg·g^(-1),遗传传递力分别为90.09%、57.62%、84.26%、91.57%。【结论】果糖、葡萄糖、蔗糖、苹果酸是由微效基因控制的数量性状。草酸、枸橼酸、琥珀酸可能是由2对主效基因控制的质量性状,并受微效基因影响;分别控制琥珀酸、枸橼酸含量的2对基因间可能存在互补作用。

为探索不同品种苹果对苹小卷叶蛾生长发育和繁殖的影响,在温度(26±1)℃、相对湿度(80±5)%、光周期L∶D=16 h∶8 h的室内条件下,测定了苹小卷叶蛾在小国光、大国光、红玉、祝光、红星和金帅上的发育历期、存活率和产卵量,并组建了其各自的生命周期表。结果显示,苹小卷叶蛾在6个品种上的发育历期差异显著,全世代发育历期以小国光最短(33.95 d),以红玉最长(39.76 d);平均单雌产卵量以红玉最高(107.24粒),小国光次之(85.00粒);而存活率则无显著差异。生命表参数中净生殖率(R0)、内禀增长率(rm)和周限增长率(λ)均以小国光最高,世代平均周期(T)和种群加倍时间(Dt)以小国光最短,表明6种试验品种中小国光是苹小卷叶蛾最适宜的寄主品种。

In this White Paper we present the potential of the enhanced X-ray Timing and Polarimetry(eXTP) mission for studies related to Observatory Science targets. These include flaring stars, supernova remnants, accreting white dwarfs, low and high mass X-ray binaries, radio quiet and radio loud active galactic nuclei, tidal disruption events, and gamma-ray bursts. eXTP will be excellently suited to study one common aspect of these objects: their often transient nature. Developed by an international Consortium led by the Institute of High Energy Physics of the Chinese Academy of Science, the eXTP mission is expected to be launched in the mid 2020s.

通过对20个苹果杂交组合的587侏后代本性状的遗传倾向的研究看出,在河南郑州地区,苹果杂种的童期一般为5年,6年生苹果杂种实生苗一般开花株率为25％,7年生可达50％以上;童期的长短主要受亲本的制约;干周15cm为杂种植株童期即将结束或已结束的标志。苹果杂种初次开花结果的部位主要为短果枝,约占60％,大多数杂种具有腋花芽结果习性。苹果杂种的果实一般均小于亲中值,平均较亲中值小38.5％。色泽的遗传表现为红对黄为显性,但在红×红的后代中有相当比例的绿黄果。果实的风味遗传相当复杂,但无论甜×酸或甜×甜,后代中果实风味酸甜的所占比重最大,并且甜×甜的后代中可出现甜的类型。富士和金冠是培育优质新品种的最好亲本;新红星的红色遗传传递力似乎较强。
