Amerancain tested were highly susceptible, on which phylloxera survival rate remained 40%~60% in 29 days after inoculation, and relatively stable thereafter. In parallel, phylloxera produced 7~12.35 eggs per day and summed up to the total of 190 eggs.
所有供试欧亚种和欧美杂交种的栽培品种都对根瘤蚜高度敏感,接种后第29d蚜虫存活率仍保持在40%~60%,且前后变化较小,日产卵量变化于7~12.35粒之间,总产卵量均在190粒以上。

Results showed that the rootstocks RSB, Gravesac, 520A and 225R were immune to phylloxera infestation. Fercal, 1613C and the HPDs was resistant to phylloxera to some extent, whose tuberosities % were less than 27%. The Both Henan wild grapes and V. adenocluda were highly sensitive to phylloxera,whose tuberosities were 66.25% and 56.67% and phylloxera produced 181.67 and 277.67 eggs on each of them; V.guangxi-quinquangularis had low resistance, whose tuberosities were 15.45%, its hybrid with a V.vinifera variety NW196 was sensible to phylloxera, whose tuberosities and egg number phylloxera produced were 46.13% and 55.28% higher than V. guangxi-quinquangularis.
结果表明:砧木RSB、Gravesac、520A和225R对根瘤蚜免疫,砧木Fercal、1613C和供试的种间杂种对根瘤蚜有一定抗性,根瘤比例均低于27%;河南野葡萄和腺枝葡萄对根瘤蚜敏感,根瘤比例分别为66.25%和56.67%,总产卵量分别达到181.67粒和277.67粒,广西毛葡萄对根瘤蚜有一定抗性,根瘤比例为15.45%,其与粉红玫瑰的杂交后代NW196抗性下降,产卵量与根瘤比例分别比广西毛葡萄高46.13%和55.28%。

Algorithms describing links between potentially important explanatory variables to estimate fecundity were first established, and these were followed by practical observations in order to validate the method under two extreme situations: 1 straight forward fecundity estimation in a determinate, single-batch spawner: Atlantic herring Clupea harengus and 2 challenging fecundity estimation in an indeterminate, multiple-batch spawner: Japanese flounder Paralichthys olivaceus.
首先确立潜在重要解释性变化与繁殖力间联系的算法,然后是为了确定下面两种情形下使用的方法的实际观察:1)在确定的单次产卵类型中直接的繁殖力估计:大西洋鲱鱼 Clupea harengus 2)确定的分批产卵鱼类竞争性的繁殖估计:日本牙鲆 Paralichthys olivaceus 。

From April to September, several clusters of bamboos, 3 ~ 4 m long, 1 ~ 2 m wide, were set on the sea bed at a depth of 16 to 20 m to attract their spawning, and the egg-strings were then transported to the laboratory. When the development of the embryo reached stage 24, iris of eyes being prominent as a colour circle and statolith being formed, they were transferred into different rearing conditions, i.e., 20, 25, 30, 35 o/oo and 15, 20, 25, 30 oC. The durations from stage 24 to hatching were different among all different rearing conditions. The statoliths were extracted and mounted in Crystal Bond thermoplastic cement for reading their growth rings.
每年的四月到九月为东北角软丝主要的产卵季节,竹丛被设置在沙质海床上吸引成熟的个体前来产卵,将采集到的卵串带回实验室中培养,当胚胎发育至第二十四期的时候(胚胎的虹膜及平衡石开始生成),这些胚胎分别被转换至不同的温度及盐度条件之下培养,温度被控制在15, 20, 25, 30 oC 四种条件下,盐度则分为20, 25, 30, 35 o/oo 四种条件,共组成十六种不同的培养条件,从平衡石生成至幼体孵出所需要的时间随著培养条件的不同而有所差异,孵化所需要的时间会随著培养的温度而有很大的变化,低温的条件会将所需的时间增长许多,在正常的条件下(25oC,35o/oo),从平衡石出限制肤出约需要9~16天。
