Abstract

ABSTRACT The planting of unconventional vegetables has increased in Brazil. This is mainly due to the demand of nutritionally rich foods grown in sustainable crops. In this scenario, ora-pro-nobis stands out, as, although being part of the meal of large part of the Brazilian population, it has been cultivated despite the lack of scientific knowledge. Thus, this study aimed to adjust a leaf area estimation model for ora-pro-nobis, using the measurements of the leaves. For the model adjustment and validation, 4000 leaves were collected in four different genotypes, being 1000 in each of them. The regression models were adjusted using 2000 independent and random observations, using 500 leaves per genotype. Thus, the observed leaf area was studied as a linear function of the dimensions of the leaf blade: length (L), width (W) and product (LW). The remaining 2000 observations, also 500 per separate genotype, were used only in the statistical validation study. The adjusted allometric model based on the product (LW) proved to be precise and accurate for estimating the leaf area of ora-pro-nobis, being applicable to any of the four genotypes analyzed regardless of the leaf size: L A ^ L W = 0.9294 + 0.6815 x L W.

估算ora-pro-nobis基因型叶面积的异速生长模型

非传统蔬菜的种植在巴西有所增加。这主要是由于对可持续作物中生长的营养丰富的食物的需求。在这种情况下，ora-pro-nobis脱颖而出，因为尽管它是大部分巴西人膳食的一部分，但它在缺乏科学知识的情况下仍被种植。因此，本研究旨在利用叶片的测量值来调整ora-pro-nobis的叶面积估算模型。为了进行模型调整和验证，收集了4个不同基因型的4000片叶片，每个基因型1000片。利用每个基因型500片叶片的2000个独立随机观测值对回归模型进行校正。因此，观察到的叶面积被研究为叶片尺寸的线性函数:长度(L)，宽度(W)和积(LW)。剩下的2000个观察结果，每个单独的基因型也有500个，仅用于统计验证研究。结果表明，基于积(LW)的调整异速生长模型准确准确地估计了ora-亲nobis的叶面积，适用于分析的四种基因型中的任何一种，无论叶片大小:la ^ LW = 0.9294 + 0.6815 x LW。
