Lemon_acidity


ABSTRACT: Samples from fruit juice vesicle tissue from three lemon genotypes (Frost Lisbon, Faris "sour" and Faris "sweet") differing in fruit acidity were compared at two developmental timepoints (immature, mature). Faris lemon appears to be a graft chimera with the L2 layer derived from normal acid lemon and layer L1 from Millsweet limetta or a closely related genotype. Fruit of Faris sour and Faris sweet grew on different branches of the same tree, with sour fruit developing on branches with L1 and L2 from acid lemon. genotype: Faris sweet lemon - developmental stage: PO:0007009 FF.01 fruit size 30%,(3-replications); genotype: Faris sweet lemon - developmental stage: PO:0007050 FR.03 late stage of fruit ripening,(3-replications); genotype: Faris acid lemon - developmental stage: PO:0007009 FF.01 fruit size 30%,(3-replications); genotype: Faris acid lemon - developmental stage: PO:0007050 FR.03 late stage of fruit ripening,(3-replications); genotype: Frost Lisbon lemon - developmental stage: PO:0007009 FF.01 fruit size 30%,(3-replications); genotype: Frost Lisbon lemon - developmental stage: PO:0007050 FR.03 late stage of fruit ripening,(3-replications) PLEXdb (http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Mikeal L.

The sour taste of lemons (Citrus limon (L.) Burm.) is determined by the amount of citric acid in vacuoles of juice sac cells. Faris is a "sweet" lemon variety since it accumulates low levels of citric acid. The University of California Riverside Citrus Variety Collection includes a Faris tree that produces sweet (Faris non-acid; FNA) and sour fruit (Faris acid; FA) on different branches; it is apparently a graft chimera with layer L1 derived from Millsweet limetta and layer L2 from a standard le  ...[more]
