The tolerance to low temperature and low light were tested on 8 cultivars.The preliminary results showed that the treatment of 15℃/5℃(day/night)、4000lx light intensity for 15 days in seedlings was determined as optimal stress for screening breeding materials tolerant to low temperature and low light intensity.Under this stress environment,low temperature tolerant cultivars showed neither chilling injury nor fallen leaves while sensitive cultivars shed leaves,the growing point become...

The tolerance to low temperature and low light were tested on 8 cultivars.The preliminary results showed that the treatment of 15℃/5℃(day/night)、4000lx light intensity for 15 days in seedlings was determined as optimal stress for screening breeding materials tolerant to low temperature and low light intensity.Under this stress environment,low temperature tolerant cultivars showed neither chilling injury nor fallen leaves while sensitive cultivars shed leaves,the growing point become black and withered.There was significant difference between tolerant and sensitive cultivars.The chlorophyll content in leaves of low temperature tolerant cultivars increased during treatment while that of the sensitive cultivars decreased.It is concluded that this result may lay a reliable foundation for further improving the evaluation of cultivars tolerant to low temperature and low light intensity.

通过在不同的低温弱光条件下,对8个代表性品种的冷害发生发展规律的研究,初步确定:15℃/5℃(昼/夜)、光照强度4000lx、光照时间8h、处理15天,是耐低温弱光品种的适宜选择压力。在此条件下,耐低温品种不出现伤害症状和落叶现象,叶片生长速度快;不耐低温品种生长缓慢,落叶严重,且生长点呈黑褐色,以至干枯。品种间差异显著。同时,耐低温品种叶片叶绿素含量增加,而不耐低温品种叶绿素含量下降。这一结果为进一步完善耐低温弱光品种的鉴定方法提供可靠的依据

Beau seedlings stressed by low temperature (4℃±1℃ ) in darkness for 12 h were treated with middle temperature and low light intensity (15℃±1℃, 72 μmol· m-2·s-1 ), high temperature and high light intensity (20℃±3℃, 224 - 340 μmol· m-2·s-1 ), and low temperature and low light intensity (4℃±1℃, 72 μmol· m-2· s-2), respectively. In the chilled seedlings treated with low temperature and low light intensity,and high temperature and high light intensity,the contents of MDA increased continuously during two days,the lower activities of SOD,POD and CAT were keeped,the electrolyte leakage of plasmalemma reached their maxima at the first day and then decreased slowly. But in ones treated with middle temperature and low light intensity,the content of MDA increased less, the activities of SOD, POD and CAT recovered more rapidly, the electrolyte leakage of plasmalemma approached normal value after two days, the chilled seedlings restored more quickly. Use of the chilling protective agent mefluidide could reduce chilling injury of beau seedlings and accelerated them restoration.

The effect of low temperature and low light intensity on the translocation and partition of 14 C assimilates in 5 cucumber cultivars was studied.The results showed that the 2 temperature treatments,20℃/10℃(day/night)and constant 15℃,accompany with irradiance of 100μE·m -2 ·s -1 with a daylength of 8hr,significantly reduced the translocation of 14 C assimilates,thus making an extremely significant difference with the control.The translocation of 14 C assimilates to other leaves was significantly reduced,while those in the meristem,stem and root were not.Significant difference was not found in the translocation and partition of the assimilates in different parts of different cultivars under low temperature.

在低温和弱光下对5个不同来源的黄瓜品种苗期14C-同化物运输分配进行了研究。结果表明,两种低温20℃/10℃(昼/夜)和15℃持续低温均明显地抑制了喂叶同化物的运输率,与对照均呈极显著差异。显著的抑制部位是向其它叶的运输,而生长点、茎和根系部分均未受到抑制,与对照无明显差异。低温下不同品种间的不同部位的同化物的运输分配均未出现显著差异。
