摘　　要：对观赏向日葵进行不同播期的种植和观察,试验结果表明:不同播期观赏向日葵的不同生育阶段和生物学性状间的相关系数有较大的显著性差异;不同生育期和生物学性状组合间的典范相关分析表明,春播植株主要表现在于全生育期与单株成花分枝数、花期与单株花数的相互关系上;夏播植株主要表现在营养生长期与单株分枝数、籽粒成熟期与单株花数的相互关系上;秋播植株主要表现在全生育期与成花分枝数和茎粗的相互关系上;冬播植株主要表现在全生育期和花期与单株花数,籽粒成熟期与成花分枝数的相互关系上。Ornamental sunflowers with red petals sowed in different seasons used to study the correlation between growth period and biological characters . The results showed that there were very significant differences in correlation coefficients in growth period characters and biological characters of sunflowers sowed in different seasons. The results of canonical correlation analysis indicated that there were significant correlation of canonical coefficients between growth period characters and biological characters. GP was related to NRF in the sunflowers sowed in spring. DSM was related to NF in the sunflowers sowed in summer. GP was related to WH in the sunflowers sowed in autumn. And DSM was related to NRF in the sunflowers sowed in winter.
