以茄子砧木品种茄砧1号和接穗品种快圆茄为试材,采用显微观察等方法,研究不同夜温(19、24、29 ℃)对茄子套管嫁接苗愈合速率及质量的影响.结果表明:在29 ℃昼温条件下,随着夜温的升高,茄子嫁接苗接合部愈伤组织细胞层数增加,接合部直径增大,但维管束连接及愈合进程减缓,木质部输导能力减弱,愈合质量下降.夜温为19 ℃的处理,嫁接后第13天隔离层完全消失,维管束连接,愈合进程较快,木质部输导能力比夜温29 ℃处理提高了72.89%;夜温为29 ℃的处理,嫁接后前9 d愈伤组织产生较多,接合部直径明显增大,比夜温19 ℃处理提高了13.35%,但愈合进程较慢.综上,在昼温29 ℃的情况下,夜温19 ℃最有利于茄子嫁接苗的愈合.

Taking eggplant(Solanum melongena L.)'Qiezhen No.1'as rootstock and 'Kuaiyuanqie'as scion,this experiment designed treatments with different temperatures(19 ℃,24 ℃,29 ℃)at night to study the effect of different night temperature on the rate and quality of healing in tube grafted eggplant seedlings by microscopic inspection.The results showed that the layers of callus cells were increased and the diameters of joint part were enlarged.While,the process of vascular connection and healing was slowed down,the xylem translocation ability was weakened,and the quality of healing was deteriorated.The isolation layer completely disappeared,and vascular was connected on the 13th day after grafting under treatment with 19 ℃ at night.Co-mpared to the treatment with 29 ℃,the xylem translocation ability was improved by 72.89%.Under treatment with 29 ℃ at night more callus was observed on the 9th day,the diameter of joint part was significantly increased by 13.35%,compared to the treatment with 19 ℃ at night,but the healing process was slower.In conclusion, under the condition of 29 ℃ day temperature,19 ℃ is the best night temperature for healing of tube grafted eggplant.
