Abstract

Abstract Solidago canadensis L. cv. Tara and Delphinium elatum, the hybrid White River are summer flowers with great agronomic potential. The goal of this study was to establish the phenology of these species grown under greenhouse conditions, as well as to determine the correlation between climatic elements (relative humidity - RH, growing degree-days for development - GDD and soil moisture - SM) with growth variables (stem length and diameter, fresh weight FW - and dry weight - DW) in S. canadensis and D. elatum. The life cycle for S. canadensis and D. elatum ended when reaching 30% of the flower opening, the stem length reached 118.05 and 123.74 cm, at 94 and 77 days, respectively. The growth of both species showed a logistic curve pattern throughout the crop cycle; S. canadensis showed maximum values for absolute growth rate (AGR) and relative growth rate (RGR) at 77 and 42 days after transplanting (DAT), respectively; in contrast to D. elatum which occurred at 77 and 28 DAT. On the other hand, for the correlation between climatic elements and growth variables in S. canadensis, the GDD and RH were directly correlated with both FW and DW, stem diameter and length, while an inverse correlation occurred for SM. D. elatum showed a direct correlation between climatic conditions and growth variables.

温室栽培下加拿大一枝黄花和飞燕草物候特征及其与小气候变量的关系

摘要加拿大一枝黄花（Solidago canadensis L.cv.Tara）和飞燕草（Delphinium elatum）、杂交白河（White River）是具有较大农艺潜力的夏花。本研究的目的是建立这些物种在温室条件下生长的酚学，并确定气候要素（相对湿度-RH、生长发育天数-GDD和土壤湿度-SM）与加拿大S.canadensis和D.elatum的生长变量（茎长和直径、鲜重FW-和干重DW）之间的相关性。加拿大S.canadensis和油麻D.elatum的生命周期分别在开度达到30%时结束，茎长分别在94天和77天达到118.05厘米和123.74厘米。在整个作物周期中，两个物种的生长都呈现出逻辑曲线模式；加拿大S.canadensis的绝对生长速率（AGR）和相对生长速率（RGR）分别在移植后77天和42天（DAT）表现出最大值；与在77和28DAT出现的D.elatum形成对比。另一方面，对于气候要素与加拿大S.canadensis生长变量之间的相关性，GDD和RH与FW和DW、茎径和长度直接相关，而SM则呈反相关。
