trinucleate

1. The ZR content varied with different genotypes in the leaves, while in the spikes and anthers, it was higher than CK from mononucleate to trinucleate stage;
   叶片中ZR含量变化随着基因型不同而有差异，而在幼穗与花药中，在花药败育的关键时期，即单核期至三核期ZR含量都高于对照；
2. Endopeptidase, BAPA, from sterile line at trinucleate stage showed cysteine-and serine types, and also part of type with metalloprotease, but it was the serine type only in maintainer line.
   不育系三核期含有的BAPA内肽酶包括半胱氨酸型、丝氨酸型，以及部分含金属酶类；
3. However, aminopeptidase in maintainer line at trinucleate pollen stage belonged mainly to the cysteine type.
   而在三核期，保持系的氨肽酶则主要为半胱氨酸型。
4. SOD activity of both types of sterile lines showed a downtrend from uninucleate stage to trinucleate stage.
   2类型不育系SOD活性从单核期到三核期都一直呈下降趋势。
