SOME RELATIONS BETWEEN LEAF AREA AND FRUIT SIZE IN TOMATOES

The effect of fruit competition and leaf area on fruit size of strawberry

Cultivar and fruit size influence bruise susceptibility and some physical properties of apple fruit

ABSTRACT- For most fruit types, including apples, bruising is the most common type of postharvest mechanical injury. Bruise susceptibility was investigated in 3 commercial cultivars (‘JazzTM’, ‘Granny Smith’ and ‘Fuji’) and among a range of 4 different fruit sizes (commercial counts of 135, 120, 100, and 88) in each cultivar. Bruising was carried out by dropping a uniform round steel ball (110g...

Convergence in leaf size versus twig leaf area scaling: do plants optimize leaf area partitioning?

BACKGROUND AND AIMS Corner's rule states that thicker twigs bear larger leaves. The exact nature of this relationship and why it should occur has been the subject of numerous studies. It is obvious that thicker twigs should support greater total leaf area ([Formula: see text]) for hydraulical and mechanical reasons. But it is not obvious why mean leaf size ([Formula: see text]) should scale pos...

Some relations between Kekule structure and Morgan-Voyce polynomials

In this paper, Kekule structures of benzenoid chains are considered. It has been shown that the coefficients of a B_n (x) Morgan-Voyce polynomial equal to the number of k-matchings (m(G,k)) of a path graph which has N=2n+1 points. Furtermore, two relations are obtained between regularly zig-zag nonbranched catacondensed benzenid chains and Morgan-Voyce polynomials and between regularly zig-zag ...

Ethylene production and respiration in aging leaf segments and in disks of fruit tissue of normal and mutant tomatoes.

Leaf segments of tomato plants (Lycopersicon esculentum Mill.) of a normal strain and of two nonripening mutants rin and nor were aged in darkness. Respiration in leaf segments of all strains followed a climacteric-like pattern which was accompanied by a similar pattern of ethylene production. l-Methionine-U-(14)C vacuum-infiltrated into leaf segments at the beginning of the climacteric-like ri...
