8个甜樱桃品种在重庆高海拔山区的生物学特性评价和分析

Experimental Study on Introduction of 8 Sweet Cherry Varieties in Chongqing High Altitude Mountainous Area

为筛选适宜重庆高海拔冷落地区发展的优质甜樱桃品种,本试验以‘布鲁克斯’‘鲁玉’‘罗亚理’‘罗亚明’‘瑞德’‘萨米脱’‘桑德拉玫瑰’‘桑提娜’8个甜樱桃品种为试材,在重庆万州高海拔山区开展引种试验研究,对物候期、树体营养生长参数、芽特性、花特性、抗逆性、坐果情况进行调查分析。结果表明:初步发现较为适宜重庆的品种有‘布鲁克斯’‘罗亚明’‘鲁玉’,其中‘布鲁克斯’移栽后成活率高,芽密度最大,且芽并生率最高,花芽率高,花密度最高,坐果较好;‘罗亚明’花芽率高,花密度大,坐果率高;‘鲁玉’移栽后成活率高,年生长量较大,干径增长快,新梢长,树体高大,成花一般,但坐果率高,‘罗亚理’成活率很低,引种需要慎重。

In order to be suitable for the development of high quality sweet cherry varieties in the cold and cool altitude area of Chongqing,8 sweet cherry varieties such as'Brooks','Luyu','Royali','Royameen','Reed','Samitel','Sandra rose'and'Santina'were selected as test materials to carry out the introduction experiment in the high-altitude mountain area of Wanzhou,Chongqing.Phenological period,vegetative growth parameters,bud characteristics,flower characteristics,stress resistance and fruit setting were investigated and analyzed.The results showed that the varieties suitable for Chongqing were'Brooks','Royameen'and'Luyu',among which'Brooks'had the highest survival rate,the highest bud density,the highest bud co-growth rate,the highest flower bud rate,the highest flower density and the best fruit setting.'Royameen'had high flower bud rate,high flower density and high fruit setting rate.After transplanting,'Luyu'had a high survival rate,large annual growth,fast growth of dry diameter,long shoots,tall tree body,general flower,but high fruit setting rate and low survival rate of'Royali',so the introduction should be careful.
