摘要:
以桃砧木品种Nemaguard为试验材料，采收七成熟至十成熟4个成熟度的果实后取种，研究4 ℃冷藏处理对不同成熟度桃砧木种子在常温（25 ℃）下萌发及对幼苗生长的影响。结果表明，随冷藏时间延长，不同成熟度果实种子的发芽率、发芽势、发芽指数均提高，种子的萌发速度和整齐度显著提高，当冷藏时间为60 d时，不同成熟度果实种子的发芽率达最大值，为73.33%至100.00%；在相同冷藏时间下，九成熟果实种子的各发芽指标总体高于其他成熟度，低温冷藏30 d发芽率即可达100.00%；低温冷藏对播种后幼苗的营养生长有较大影响，不同成熟度果实种子萌发后的幼苗总体表现为株高与茎粗随冷藏时间延长而缓慢增加，在低温60 d时达到最大值，其中九成熟果实种子萌发后的幼苗株高总体高于七成熟与十成熟；种子低温冷藏时间同时影响幼苗叶片发育，当种子冷藏时间少于30 d时，不同成熟度果实种子播种后幼苗莲座叶现象明显，冷藏时间达50 d后，幼苗莲座叶现象消失。
Abstract:
The seeds of peach rootstock cultivar Nemaguard with four different fruit maturities (70% maturity to 100% maturity) were used to study the effects of cold storage treatment at 4 ℃ on the germination and seedling growth of seeds with different maturities at room temperature (25 ℃). The results showed that, the germination rate, germination potential and germination index of seeds of different fruit maturities were all increased with the extension of cold storage time, and the germination speed and uniformity of seeds were also increased significantly. The germination rates of all seeds of different fruit maturities reached the maximum value and ranged from 73.33% to 100.00% when the cold storage time was 60 d. The germination indicators of the seeds of 90% fruit maturity were generally higher than the seeds of other fruit maturities under the same cold storage time, and the germination rate could reach 100.00% after 30 d of low temperature treatment. Cold storage showed great impact on the vegetative growth of seedlings after sowing, and the plant height and stem diameter of seedlings germinated from seeds of different fruit maturities generally increased slowly with the extension of cold storage time, which reached the maximum after low temperature treatment for 60 d. The plant height of seedlings germinated from seeds of 90% fruit maturity was generally higher than those of 70% and 100% fruit maturities. Development of seedling leaves was affected by cold storage time of seeds. Rosette leaf phenomenon of seedlings was obvious when the cold storage time of seeds was less than 30 d. When the cold storage time of seeds reached 50 d, the rosette leaf phenomenon of all seedlings disappeared.
