Effects of Stored Pollens from Wild <i>Actinidia eriantha</i> Vines on Some Fruit Quality Traits

Abstract

Our study was conducted to determine In vitro germination ability of pollens from 25 wild Actinidia eriantha genotypes after one year freeze storage, afterwards we examined fertilization ability of stored pollens of 8 genotypes selected according to In vitro test results from aforementioned 25 genotypes, and finally investigated effects of stored viable pollens from "MH67", "MH55", "MH48" and "MH45" genotypes on fruit quality characters of the female experimental plant "M3" as the main purpose. Non-pollinated "M3" kiwifruit plant was taken as control. We found that In vitro germination and fertilization ability of different stored pollen sources, and also fruit quality characters including dry matter, total sugar, titratable acid, vitamin C, total polyphenol, total flavonoid, chlorophyll ("a", "b", and total) and carotenoid contents except total soluble solid content were significantly different. MH67 and MH45 genotypes were evaluated as the most suitable pollenizers which can be recommended as new candidate cultivars because of long term storage ability and brought about desired fruit quality characters. They also will be investigated more at further breeding studies.

The choice of female or male parent affects some biochemical characteristics of fruit or seed of kiwiberry (Actinidia arguta)

“…1a). Similar results were obtained by Seyrek et al (2017). They found that the DM content of Actinidia eriantha fruit pollinated by male genotype MH67 increased significantly (up to 18.3% DM) in comparison to control pollinations (16.8% DM).…”

“…However, the authors of that study did not find any effect of pollen source on TPC. In contrast, significant differences in TPC in Actinidia eriantha pollinated with different pollen sources were observed by Seyrek et al (2017). The authors reported TPC concentrations in A. eriantha in the range 0.26-0.56 mg g -1 FW.…”

“…There is very little information about effect of different pollen sources on carotenoids and chlorophylls concentrations in fruits or vegetables. Variation in carotenoids and chlorophyll concentration in Actinidia eriantha pollinated with various pollens was observed by Seyrek et al (2017). They investigated the effects of four different pollen sources on selected traits of A. eriantha fruit.…”

“…In contrast to many other diploid A. chinensis genotypes, pollination of the cultivar 'Hort16A' by males of higher ploidy may be beneficial in terms of fresh fruit weight (Seal et al 2013). An interesting study of the xenia effect on the chemical composition of A. eriantha fruits was recently made in China (Seyrek et al 2017). The authors found that vitamin C, flavonoid, carotenoid and chlorophyll concentrations in fruit pollinated with different pollen sources differed significantly.…”

Removal of Cr(vi) and p-chlorophenol and generation of electricity using constructed wetland-microbial fuel cells based on Leersia hexandra Swartz: p-chlorophenol concentration and hydraulic retention time effects

“…0.1 g of fresh leaves were used to measure the chlorophyll a, chlorophyll b and carotenoid levels of L. hexandra using the acetone method. 34 The total phenolic content of the plant leaves was determined using the Folin–Ciocalteu method. 35 …”
