“…In a study with Citrus sp. using SEM (SINGH et al, 2020), the authors could distinguished genotypes using agronomic and leaf anatomic traits, which play an important role in studying diversity. According to ENDO & TORII (2021), molecular mechanisms allowing exploration of those traits in big crops, including coffee, are still needed to be fully understood.…”

“…Microscopy techniques, including light and electron microscopy, allow evaluation of morphoanatomy diversity in distinct plant tissues (LUSA et al, 2018;SINGH et al, 2020). Electron microscopy, in particular, is an efficient versatile tool in plant anatomy studies by producing high-resolution images (STABENTHEINER et al, 2010;GUL et al, 2019).…”

“…Among plant organs, microscopy studies with leaves have been conducted in several crops (SCHOLLERT et al, 2015;FARALLI et al, 2019;SINGH et al, 2020). Leaves are essential to plants, since they are responsible for supplying photoassimilates; and therefore, are one of the first organs responding to unbalances in plant metabolism (TAIZ & ZEIGER, 2017).…”

Genetic variability is the basis for coffee genetic breeding. This study evaluated the potential of leaf anatomy and morpho-agronomic traits in studies of genetic variability in C. canephoracultivars. Ten genotypes were distributed in randomized block designs with three replicates. Significant differences among genotypes were detected by F-test (P < 0.05) for 13 of 15 evaluated traits. These results evidenced the heterogeneity of the studied cultivars, which is essential in composition of genetic basis in breeding programs. The Scott-Knott test detected variability among genotypes, grouped into up to four mean groups. Leaf anatomy traits presented the largest variations. Five out of seven leaf anatomy traits presented heritability higher than 80%, with emphasis on stomatal density (95.69%) and stomatal pore length (92.72%). Positive correlations were observed among morpho-agronomic and anatomic traits. Cluster analysis used the Mahalanobis general distance (D2) as a measure of genetic dissimilarity and divided the genotypes into two distinct groups. The inclusion of leaf anatomic traits to characterize C. canephoragenotypes may assist plant breeders with better genetic discrimination and with greater security in plant selection when composing cultivars.

There is little information on pollen morphological analysis of papaya cultivars with different flesh color and origins. We observed pollen morphological characters of 17 papaya cultivars through scanning electron microscopy. The results showed that papaya pollen grains were monads, tricolporate, and small and medium-sized. The pollen grains were oblate-spheroidal to spheroidal. Foveolate, reticulate, and fossulate exine ornamentation were observed. Colpi width had maximum coefficient of variation of 25%; Shannon diversity index of all qualitative characters reached over 0.8. Using cluster analysis, 17 papaya cultivars were divided into three groups; there was no relationship between flesh colors and origins. The study findings suggest that pollen morphological analysis is valuable to provide references for breeding and genetic improvement of papaya.
