Abstract：In order to investigate the cause of tomato cluster bending phenomenon,18 spring tomato varieties in a solar greenhouse were surveyed for the different levels of cluster length,cluster diameter,fruit number,cluster bending condition in north and south regions of the greenhouse.The results showed that under spring cultivation condition the cluster bending rate of different tomato varieties was significantly different,among which Zhengfan 12152,Zhengfan 12165 and 12158 were more than 80.00％ and the rate Zhengfan 1203,Meishuai,Boya and 15MG were lower than 20.00％.The cluster length and thickness of different varieties of tomato were different,the longer and thinner the cluster,the higher the bending rate of the cluster.Concerning each cluster the bending rate of different varieties also varied greatly.The bending rate of the first cluster was 0,while the bending rate of the second,third,fourth and fifth cluster was different.At the same time,the cluster bending of tomato was related to the number of the single panicle.The more the number of the fruit per panicle,the higher the bending rate of the cluster.In addition,cluster bending was also related to the distribution area,and the average bending rate in the southern region was lower than that in the northern region by 10.76％.Therefore,the cluster bending phenomenon of spring tomato in solar greenhouse may be related to many factors.
