- 摘要:
- 以‘新优亮K21’黄瓜为试验材料，采用5种光质（红R、蓝B、红蓝比7R/1B、红蓝比5R/1B、自然光CK）对种子及幼苗进行处理，研究了不同光质对黄瓜种子萌发、幼苗生长及幼苗抗寒性的影响，以期筛选对黄瓜生长最优的光质。结果表明：R处理下种子发芽率最高，比CK高25.98%，且株高、鲜质量、干质量、根长等指标都随着复合光之中红光所占比例增大而逐渐增大，株高以R处理最高，比CK高1.23 cm；茎粗以7R/1B处理最好，比CK高0.43 mm；根长以7R/1B处理最大，比CK长1.00 cm；幼苗经低温处理后，各处理相对叶绿素含量、电解质渗透率、超氧化物歧化酶（SOD）活性、过氧化物酶（POD）活性及过氧化氢酶（CAT）活性均发生变化，且在处理第5天存在显著性差异，抗寒性表现最优的光质为5R/1B。综合以上情况得出，对黄瓜生长发育最优光质处理为5R/1B和7R/1B。
- Abstract:
- Taking ‘New bright K21’ cucumber as experimental materials and the seeds with five kinds of quality of lights (red R；blue B；7 red and 1 blue，7R/1B；5 red and 1 blue，5R/1B；natural light as CK) were treated to study the effect of different light qualities on cucumber seed germination，seedling growth and cold resistance of the seedlings，in order to select the best light quality for cucumber.The results showed that R treatment of seed germination rate was the highest which was 25.98% higher than CK treatment，additionally，plant height，fresh weight，dry weight，root length and other indicators increased as the compound light red proportion increased.The plant height of R treatment was the highest which was 1.23 cm higher than CK treatment.7R/1B was the best treatment for stem diameter，0.43 mm wider than CK treatment；the root length was the longest with 7R/1B treatment as well which was 1.00 cm longer than CK treatment.After low temperature treatment，the relative chlorophyll content，electrolyte leakage，SOD activity，POD activity and CAT activity of the seedling were changed，and on the fifth day there was a significant difference.The optimal quality for cold resistance was 5R/1B.Based on the above analysis，the best optimal light treatment for growth of cucumber were 5R/1B and 7R/1B.
