“…Uma and Arun (2016) observed thinning of the pollen tube population within the style, thus reducing the number of pollen tubes likely to enter the ovary -a different observation from that of Dodds (1945). Soares et al (2014) working in Brazil, observed necrosis in the prolongation region of the ovary in triploid cultivars (AAA and AAB), whether pollinated or not. In diploid cultivars no necrosis was observed.…”

“…Different techniques are cited in the literature to investigate the occurrence of viable pollens in several species and these are grouped in direct methods, such as in vitro germination [7,8,9] and in vivo [9,10,11] or indirect based in cytological parameters such as staining [9,11,12,13].…”

The causes of fruit abortion, in eggplants, may be related to the absence of viable pollen under high temperatures, common in the Northeast region of Brazil, resulting in a reduction in the number of fruits per plant and consequently in productivity. The objective of this study was to evaluate the techniques of identification of PV – pollen viability in eggplant, as well as to correlate these results with the FFI – Fruit Fixation Index, NFP – Number of Fruits per Plant and PP – Production per Plant obtained in cultivation under high temperatures. The experiment was conducted at the Federal Rural University of Pernambuco, Recife, Brazil, between September and December 2017. The experiment design was a randomized block design with four replications, in the 7 x 4 factorial scheme (7 genotypes x 4 evaluation of PV) containing four plants per experimental plot. The results showed that the different techniques used detected viable pollens in the genotypes evaluated in smaller and in larger proportions. The highest percentages were observed in the treatments with CA – Carmine Acetic and AS – Alexander Solution and these overestimated the PV (>90%). In the test with TTC – 2,3,5-triphenyltetrazolium chloride (25%), the viability estimation was equivalent to the in vitro germination test, however the genetic correlations were null and/or very low between these techniques and the FFI, NFP and PP traits. The genetic correlations between the results obtained with CA and AS with FFI, NFP and PP under conditions of high temperatures were high and positive and suggest that the selection based on PV only, except with the use of TTC solution, may be efficient for indirect selection of genotypes with high FFI, NFP and PP.

“…This observation may also suggest that arrest of pollen tube growth may be a biochemical rather than a physical process. It is supported by the fact that a necrosis is not formed in the prolongation fruit zone of diploids (Soares, et al 2014).…”

“…This implies that there are other factors which come into play after pollen has germinated on the stigmas in different hand positions. The necrosis formed in the prolongation zone of fruits after anthesis especially in triploids (Soares et al, 2014) could partly account for absence of seed set in proximal hands. This necrosis acts as a barrier to pollen tube growth.…”

Background: Low female fertility in bananas is the biggest hurdle for banana breeding. The aim of this study was to determine seed set patterns in East African cooking bananas EACBs to inform future decisions on a more targeted approach of increasing seed set and subsequently banana breeding efficiency. Matooke (AAA) and Mchare (AA) bananas are genetically distinct but belong to the same genetic complex, they referred to as EACBs. Seed set patterns in ‘Enzirabahima’ (AAA), ‘Mshale’ (AA) and ‘Nshonowa’ (AA) all with residual fertility were examined after hand pollination with a highly male fertile wild banana ‘Calcutta 4’ (AA). Results: Seed set in ‘Enzirabahima’ is predominant in distal hands. Mchare cultivars have a slightly more even distribution of seeds in their hands compared to ‘Enzirabahima.’ There is a gradual increase in seed set from proximal to distal hands with a slight drop in the last hand. This pattern is more definite in ‘Enzirabahima’ and ‘Mshale’ while ‘Nshonowa’ has a somewhat inconsistent pattern. There is also a drop in seed set per 100 fruits per hand from small to larger bunches. However, larger bunches have a higher pollination success compared to smaller bunches. They therefor set more seed on 100 fruits per hand and per bunch basis if bunches without seed are accounted for. Pollination success rate increases from smaller to larger bunches of EACBs. Seed set is biased toward the distal third part of fruits of examined EACBs as well tetraploid Matooke hybrid ‘401K-1’ (AAAA) and improved diploid ‘Zebrina’ GF (AA) that were used for comparison. In comparison, in the highly female fertile ‘Calcutta 4,’ seed set is along the entire length of the fruit.Conclusion: Seed set bias in the distal hands and distal end of fruits suggests a systematic mechanism rather than a random occurrence. It is expected that this information will provide a foundation for increased crossbreeding efficiency in bananas.
