摘要
2009年以陕西杨凌的酿酒葡萄品种赤霞珠为材料,在自然条件下研究了果实外观和物理性状、果粒纵横径、质量、容积的变化规律,为葡萄栽培措施提供理论依据。结果表明:赤霞珠果粒纵横径的变化呈"单S"型曲线,分为3个时期,即快速生长期(6月1～22日)、缓慢生长期(6月22日至7月20日)和平稳生长期(7月20日至8月22日)。在快速生长期,果粒纵径和横径变化最大,纵径日均增长率为15.61%,占总生长量的64.48%;横径日均增长率为17.61%,占总生长量的60.84%。赤霞珠果粒质量和容积的变化呈"双S"曲线,分为4个时期,即极快生长期(6月1～22日),缓慢生长期(6月22日至7月15日),快速生长期(7月15～26日)和平稳变化期(7月26日至8月22日)。极快生长期变化最大,果粒质量和容积日增长率分别为691.75%和561.67%,分别占总生长量的44.45%和45.49%;快速生长期果粒质量和容积日增长率为4.30%和3.92%,分别占总生长量的30.69%和28.51%。
The change regularity of appearance and physical characteristics,longitudinal and traverse diameters,weight and volume of Cabernet Sauvignon berry were investigated at Yangling,Shanxi province in 2009.The results showed as follows:Firstly,the changes of longitudinal and traverse diameters of Cabernet Sauvignon berry showed single'S'curve,it was divided into 3 periods:rapid growth period(from June 1th～22th),slow growth period(from June 22th to July 20th) and stable growth period(from July 20th to August 16th ).For rapid growth period,the changes of longitudinal and traverse diameter of berry were the largest,daily growth rate of it were 15.61%and 17.61%, respectively,accounting for 64.48%and 60.84%of total growth.Secondly,the changes of weight and volume of Cabernet Sauvignon berry showed double S curve,it was divided into 4 periods:very rapid growth period(from June 1th to 22th),slow growth period(from June 22th to July 15th),rapid growth period(from July 15th to 26th) and stable growth period(from July 26th to Agust 16th).The changes of the berry weight and volume were the largest in very rapid growth period,the daily growth rate of it were 691.75%and 561.67%,accounting for 44.45%and 45.49%of total growth,respectively.While the daily growth rate of weight of volume was 4.30%and 3.92%in rapid growth period,accounting for 30.69%and 28.51%of total growth.
