Research Progress of Heat-tolerance of Brassica campestris ssp. Chinensis

Agricultural Science & Technology 2013年第2期14卷 248-253页

作者：赵晓东张景云范淑英缪南生江西农业大学农学院江西南昌330045 江西省农业科学院蔬菜花卉研究所江西南昌330200

Brassica campestris ssp. chinensis, also known as non-heading Chinese cabbage, is an important vegetable widely distributed in southern China. High temperature is the most common adversity factor in vegetable production, because Brassica campestris ssp. chinensis is a thermophilic vegetable, which can＇t well grow at high temperature. In summer and autumn, high temperature stress would prevent Brassica campestris ssp. chinensis from growing and result in poor quality of its seedlings, seriously influencing yield and quality of the vegetable in later period. In this paper, present situation and latest advances in heat resistance research of Brassica campestris ssp. chinensis in recent years were reviewed at home and abroad. The research tendency in Bassica campestris ssp. chinensis was also described, providing reference for breeding of heat-resistant Brassica campestris ssp. chinensis.

为研究离体条件下盐胁迫对二倍体马铃薯富利亚(Solanum phureja,PHU)和窄刀薯(***,STN)杂种(PHU-STN)无性系相关生理指标变化。以6项生长参数筛选出的耐盐、中耐盐、感盐无性系各5份为试验材料,建立耐盐程度不同的3个组,包括四倍体耐盐品种Bintje和感盐品种Mainechip,用浓度为30 mmol·L-1的NaCl进行不同天数胁迫,测定叶绿素含量、超氧化物歧化酶(SOD)和过氧化物酶(POD)活性变化。随着盐胁迫天数的延长,叶绿素含量、SOD、POD活性相对值均呈降低趋势;二倍体马铃薯组间叶绿素含量、SOD和POD差异极显著。因此,叶绿素含量、SOD和POD活性与二倍体马铃薯耐盐性有关。
