赞皇大枣

3提高空气中CO2浓度，可以提高赞皇大枣净光合速率，但并不改变Pn的日变化规律。

The Pn of Zanhuang-jujube were raised in high CO2 concentration , but the regularity of diurnal changes of Pn was not changed . 4 .

主要研究结果如下：1采用4种干制方法处理赞皇大枣与金丝小枣，对干制时间、干制后枣果的感官品质、主要营养成分和cAMP含量进行了测定。

The main research results are as follows : 1 . The sense quality , main nutrition content , and cAMP content of ' Zanhuangdazao ' and ' Jinsixiaozao ' jujube , after being dried through 4 different method , has been analysed .

2赞皇大枣光合作用在晴天中午有明显的光合午休，主要原因为细胞的光合活性下降，但中午的高温、高VPD及气孔限制也有一定作用。

The obvious midday depression of Pn of Zanhuang-jujube was mainly caused by the declined mesophyll photosynthetic capacity , but the high temperature > high water vapor pressure difference between leaf and air ( VPD ) and stomatal limitation ( Ls ) also contributed to it at noon .

赞皇大枣可能是由二倍体品种未减数配子和同品种或不同二倍体品种正常配子天然杂交而来。

' Zanhuang Dazao ' might have originated from natural crossing with 2n gametes and normal gametes .

5晴天，在6～10月份中，赞皇大枣的光合日变化为双峰型。

For clear days , diurnal changes of Pn of Zanhuang-jujube were double-peaked pattern from June to October .
