马铃薯实生种子超弱发光规律的初步研究

A STUDY ON THE ULTRA-WEAK CHEMILUMINESCE OF POTATO TRUE SEED

本文对马铃薯实生种子的超弱发光规律进行了初步研究，结果发现；不同品种的风干种子及其浸种过程中的超弱发先均有差异，综合特性好的品种其种子的发光强度高。在浸种初期种子的发光强度最高，在１２小时内，随着浸种时间的延长，发光强度逐渐降低。萌发９６小时左右时的种子，研磨粉碎后提取液的发光强度与种子的储藏年限成反比。

Abstract The result shows: the ultra-weak luminescence, of different breed potato true seeds is different, ether air-dried or soaked seed, the higher the seed quality, the higher intensity of luminesecnce it gives; during the soaking process, the highest intensity of luminescence is gived in the 2 minutes after the seed have been dipped in water, then the luminescence intensity decrease gradually during the begining 12 soaking hours.When the seed is germinated for about 96 hours, the ulha-weak chemiluminescence intensity of the water extract from the smashed seed is inversely proportional to the number of years that the seeds have been stored. In the begining 96 germinating hours, the chemiluminescence intensity of the water extract from the seeds stored for 2 years increases gradually. But that from the seeds stored for 14 years changes little; and that from the seeds stored for 7 yearsincreases from after 72 germinating hours.
