摘要：

利用河北省廊坊市日光温室‘红颜’草莓生长和气象要素观测数据，采用偏最小二乘回归（PLSR）方法，分析日光温室草莓果实生长变化特征及其与光热条件的关系。结果表明，草莓果径在整个生长发育过程中一直呈平稳增长，横径生长速度始终大于纵径，花后40 d左右开始进入快速生长期，横径增长极大值为1.43 mm·d-1。光照和热量条件是影响草莓果径增长的主要因素，光照的强弱对果实白熟期至成熟期的影响最明显，此期间光照较好能促使果实提前转色成熟。利用光照和热量条件拟合果实横、纵径增长量，拟合效果较好。

Abstract:

Based on the meteorological observations and the greenhouse strawberry growth experiment data in Langfang of Hebei Province, the correlation between the strawberry growth and light and heat conditions was analyzed by using the partial least square regression method (PLSR). The results indicate that the fruit diameter increased steadily during the whole growth period of strawberry. The vertical diameter increased slower than transect diameter. The fastest growth appeared approximately 40 days after post-flowering, the maximum transect diameter increased rate was 1.43 mm·d-1. The main factors affecting fruit diameter growth were lighting and heat. The intensity of lighting had obvious effect on the fruit from white maturing stage to maturation stage, during this period, the fruits with good light condition were able to mature ahead of time. Fitting the strawberry diameter used lighting and heat elements, the effect was very well.

Key words: strawberry, growth dynamics, heat and light conditions
