Abstract
Roots from 8 advanced generation breeding lines of carrot (Daucus carota L.) repeatedly selected for high or low total soluble solids content, and 2 selections of Tmperator 58', one with high and one with low soluble solids, were evaluated for perceived sweetness and eating quality by taste panels. Most taste evaluations were made using the Quantitative Descriptive Analysis method. Two breeding lines, 5158 and 5164, had high levels of solids (
Abstract
Demand for dehydrated onions, Allium cepa L., is becoming considerable in world markets. Any changes in dry matter, total soluble solids, or pungency of onions may affect quality of the dehydrated product. Several studies have been made on the influence of herbicides on weed control and onion yield (2, 4, 5) but little has been reported on the effects of herbicides on quality characteristics. The purpose of this study was to evaluate the effects of chlorbromuron (N'-(4-bromo-3-chlo-rophenyl)-N-methoxy-N-methylurea), chloroxuron (N’-4-(4-chlorophenoxy) phenyl-N,N-dimethylurea), propachlor (2-chloro-N-isopropylacetanilide), CP-50144 (2-chloro-2′,6′-diethyl-N-(methoxymethyl) acentilide), Sindone 0263 (1, 1-dimethyl-4,6-diisopropyl-5-indanylethylketone + 7-indanylisomer), propanil (3’, 4′-dichloropropionanilide), and prometryne (2,4-bis(iso-propylamino)-6-(methylthio)-s-triazine) on dry matter content, total soluble solids, and pungency of onions.
Increasing percent fruit total soluble solids (TSS) content has been a priority for many breeding programs. Perkins-Veazie et al. (2006) reported that the TSS content of modern watermelon [ Citrullus lanatus var. lanatus (Thunb.) Matsum
Abstract
Titratable acidity and total soluble solids were measured in F1 hybrid citrus populations involving an acidless pummelo [Citrus grandis (L.) Osbeck] and an acidless orange [Citrus sinensis (L.) Osbeck] respectively, as one parent. Three advanced crosses were also studied. Crosses of the pummelo with 5 medium acid cultivars produced no acidless individuals but many with low to medium acidity and a few with acidities above 1.6% in their main seasons of use. The overall mean titratable acidity was 1.1%. Crosses of the acidless orange with 4 medium-acid cultivars produced only a few low to medium-acid individuals, and many with acidities above 1.6%; the overall mean acidity was 2.0%, significantly higher than with the pummelo. Mean levels of total soluble solids had a range which was similar between the 2 types of crosses, although the overall mean was significantly higher in the orange crosses. There were significant correlations between acid and total soluble solids levels in only 2 out of 11 progenies among all of the crosses.
Twelve of 40 individuals were essentially acidless in an F2 population involving the acidless pummelo as a grandparent. There were no acidless individuals, but there were many moderately-acid ones in 2 populations of acidless pummelo hybrids backcrossed to acid cultivars. These proportions suggest simple inheritance for the acidless character of the pummelo. In contrast, the high acid levels of the F1 populations with acidless orange imply a different basis for the latter’s lack of acidity.
Allium plants possess organosulfur compounds and carbohydrates that provide unique flavor and health-enhancing properties. In previous studies of onion F3 families, significant phenotypic and genetic correlations have been reported between pungency, in vitro antiplatelet activity (IVAA), and soluble solids content (SSC); although in other studies SSC and pungency have not always been correlated. In this study we analyzed SSC, pungency, garlic-induced in vitro antiplatelet activity and the content of three predominant thiosulfinates in bulbs from two garlic families obtained from unrelated self-pollinated plants. A strong positive correlation was observed between pungency and IVAA for both sample sets, indicating that it will be difficult to develop garlic populations with low pungency and high IVAA. Allicin was the most abundant thiosulfinate and its content was positively correlated with pungency and IVAA (r= 0.70 and 0.74, respectively). The thiosulfinates AllS(O)SPropenyl and AllS(O)SMe were also positively correlated with pungency and IVAA. When compared with IVAA, AllS(O)SMe had higher r values than AllS(O)SPropenyl (0.88 and 0.50, respectively). These differences could reflect differential platelet anti-aggregatory properties of different thiosulfinates. SSC was not correlated with IVAA, pungency, or thiosulfinates content, suggesting that soluble solids in garlic can be independently selected.
Abstract
Using the puree juice of 1/2 fruit for soluble solids determination, it was found that for freshly harvested fruit to meet the min % soluble solids (SS) of 11.5 required by Hawaiian grade standards for marketable papayas, the fruit should have at least 6% surface yellow coloration. For postharvest ripened fruit, the min degree of surface coloring when harvested should be as least 3% for the ripened fruit to meet the min soluble solids (SS) requirement. Because the 6% surface coloration is more readily visible than the 3% level in the papaya orchard, the higher stage of coloration is recommended as a index for min harvest maturity.
