Analysis on longitudinal sections of xylem and pith of parents and progenies. Longitudinal sections of xylem: (a1) L. fauriei; (a2) L.indica ‘Pocomoke’; (a3) non-dwarf progenies; (a4) dwarf progenies. Longitudinal sections of pith: (b1) L. fauriei; (b2) L.indica ‘Pocomoke’; (b3) non-dwarf progenies; (b4) dwarf progenies. (c) Internode length of parents and progenies. (d) Pith cell length and xylem cell length of parents and progenies. (e) Pith cell number and xylem cell number of parents and progenies. Error bars represent mean ± SD. Different letters on the column indicate significance level at P < 0.01. Bar = 50 μm in (a,b). Relationships between internode length and xylem cell length (f), and between internode length and xylem cell number (g) were estimated in xylems of internodes of nine non-dwarf and nine dwarf progenies. Relationship between internode length and pith cell number (h) was estimated in piths of internodes on nine non-dwarf and nine dwarf progenies.
