摘要

本研究评估了tarumã果实和种子的形态和生物计量学。该实验于2018年3月在佩洛塔斯联邦大学进行，果实收集在位于Quedas do igua - paran的两个基质中。果实和种子的长度、宽度和厚度用数字卡尺测定。对于生物特征评估，计算所得值的算术平均值、标准差、变异系数和振幅。种子萌发过程大约在32天内开始。在整个下胚轴中，证实了颜色过渡。果实的长度和宽度分别为15 ~ 22 mm和12 ~ 18 mm。在种子的生物特征方面，可以验证种子的长度为5 ~ 13mm，宽度为4 ~ 10mm，厚度为3 ~ 7mm。在形态上，鉴定该种萌发为带保护子叶苗的附生型(显子叶)。

Morphometry of fruits, seeds and seedlings of Vitex megapotamica (Lamiaceae)

The present study evaluated the morphology and biometry of tarumã fruits and seeds. The experiment was conducted at the Federal University of Pelotas and the fruits were collected in two matrices located in Quedas do Iguaçu – Paraná, in March 2018. The length, width and thickness of fruits and seeds were determined using a digital caliper. For biometric assessments, the arithmetic mean, standard deviation, variation coefficient and the amplitude of the values obtained were calculated. The seed germination process started in approximately 32 days. Throughout the hypocotyl, a color transition was verified. It was observed that the values of length and width of the fruits varied from 15 to 22 mm and 12 to 18 mm, respectively. Regarding the biometry of the seeds, it can be verified that the length, width and thickness of the seeds varied from 5 to 13 mm, 4 to 10 mm and 3 to 7 mm, respectively. As for morphology, it was identified that the species has germination of the epigeal type with protected cotyledon seedlings (phanerocotyledons).

期刊介绍： Bothalia: African Biodiversity & Conservation is published by AOSIS for the South African National Biodiversity Institute (SANBI) and aims to disseminate knowledge, information and innovative approaches that promote and enhance the wise use and management of biodiversity in order to sustain the systems and species that support and benefit the people of Africa. The journal was previously published as Bothalia, and had served the South African botanical community since 1921. However the expanded mandate of SANBI necessitated a broader scope for the journal, and in 2014, the subtitle, African Biodiversity & Conservation was added to reflect this change.
