- 摘要:
- 以‘Sugarlee’西瓜为试材，通过观测不同发育时期主蔓长度、果实纵径、果实横径和果实质量的变化过程，研究了西瓜主蔓和果实的生长变化规律，并建立了西瓜主蔓和果实的生长发育数学模型，为西瓜高产高效栽培提供科学依据。结果表明：西瓜主蔓的生长主要分为2个时期，一个是快速生长期，一个是缓慢生长期；果实纵径、果实横径和果实质量的增长主要分为5个时期，且表现出慢-快-慢-快-慢的生长节奏；西瓜果实质量的增加量在花后12 d和22 d有2个明显的高峰。西瓜开花后天数与西瓜主蔓、果径和果实质量的回归方程，并对各指标进行相关分析。回归方程相关系数较高，拟合优度较好，置信度达到99.99%。
- Abstract:
- Watermelon cultivars ‘Sugarlee’ was used as material，the main vane length，fruit longitudinal diameter，fruit transverse diameter and fruit weight in the growth development period were measured.Growth and development regulation of main vane and fruit were reserched,mathematical model of growth and development of main vane and fruit were established in order to supply reference for high yield and high efficiency cultivation for watermelon.The results showed that there were two growth stages during the growth period.One was rapid growth stage，one was slow growth stage.There were five growth stages during the growth period，and exhibited slow-fast-slow-fast-slow rhythm.There were two growth peaks during the fruit growth period.Regression equation of days after flower and main vane，fruit longitudinal diameter，fruit transverse diameter and fruit weight were established by software.It showed that four regression equations coefficient correlation were high，and credibility was 99.99%.
