这项研究在马瑙斯北部的Adolpho Ducke森林保护区进行。本文报道了金刚藤科五种植物的物候观察。长柱草L. octandra、Couepia longipendula和C. robusta与25年的气象数据进行了分析。计算了开花期(F2)、成熟果期(F5)和新叶期(F8)的月平均发生率、频率、规律性、日期、持续时间以及个体间和群体间的同步性。L.异形花在雨季(11月至12月)的过渡期开花最多。Jan.); L. longistyla(June)和L. octandra(7月)在向旱季(5 - 7月)过渡时; longipendula和C. Robusta在旱季(10月)。这些植物的物候期出现频率为一年至超一年,开花模式不规则,但L.八雄蕊超一年生和非常不规则图案。开花期(所有物种)的平均持续时间为4.8个月和5.5个月的结果。群体开花同步性指数以L. octandra(0.79),C. longipendula(0.56)和L. heteromorpha,L. longistyla和C.粗壮(0.32)。所有物种均表现出万年青植物的特征。三个物候期的主成分分析F2、F5、Fs与气象因子的相关分析表明,开花期(F2)与降雨量、相对湿度呈负线性相关(r = -0.34),与日射量呈正相关(r = 0.29),最高温度(r = 0.26)和蒸发(r = 0.31);成熟果实(F5)与降雨量呈正相关与最低温度(r = -0.35)和日照(r = -0.27)呈负相关,新叶期(Fx)与开花期(F2)呈相似的相关。
This study was carried out in the Adolpho Ducke Forest Reserve, on north of Manaus. Phenological observations on five species of Chrysobalanaceae, Licania heteromorpha, L. longistyla, L. octandra, Couepia longipendula and C. robusta were analyzed in relation to meteorological data over 25 years. The monthly mean percentages of occurrence, frequency, regularity, date, duration of the phenophases, and the synchrony among individuals and in the population for flowering (F2), mature fruits (F5) and new leaves (F8), were calculated. L. heteromorpha showed maximum flowering in the transition to the wet season (Nov.-Jan.); L. longistyla (June) and L. octandra (July) in the transition to the dry season (May-July); C. longipendula and C. robusta in the dry season (Oct.). The species showed annual to supra annual frequency of phenophase occurrence and an irregular flowering pattern, except for L. octandra supra annual and very irregular pattern. The mean duration of the flowering (all species) was 4.8 months and 5.5 months for the fruiting. The synchronism index of flowering in the population was high in L. octandra (0.79), medium in C. longipendula (0.56) and low in L. heteromorpha, L. longistyla and C. robusta (0.32). All the species showed characteristics of evergreen plants. A principal components analysis of three phenological phases (F2, F5 Fs) and meteorological variables showed that flowering (F2) had a negative linear correlation with rainfall and relative humidity (r = -0.34), and a positive correlation with insolation (r = 0.29), maximum temperature (r = 0.26) and evaporation (r = 0.31); mature fruits (F5) showed a positive correlation with rainfall (r = 0.27) and a negative correlation with minimum temperature (r = -0.35) and insolation (r = -0.27); the new leaves phase (Fx) had correlations similar to those found for flowering (F2).
