Aditionally, plumule length (PL) and plumule dry weight (PDW) from 10 normal seedlings were measured; PL was the length (cm) from the base of the stem to the apex of the youngest leaf; and PDW (mg per seedling) was recorded after seedlings were dried in an oven at 75[degrees]C for 72h.
Plumule and radicle length traits both had reducing trend in relation to different levels of drought stress so that with more negative potential the plumule and radicle length from control to -4 bar decreased significantly 66.
Therefore, this, study is aimed at exploring the in vitro regeneration potential of BA pulse-treated plumule apice explants of highly recalcitrant lentil plants.
Routinely, the type D explants were inoculated keeping radicle side portion of cotyledonary ring portion in contact with the medium and plumule side up.
Mauseth (1988) presents a longitudinal section of the embryo of a grass species (Panicum maximum) where, similar to the embryos of corn and wheat, all the cells composing the coleorhiza are vacuolated cells whereas the cells of the radicle, plumule and even the coleoptile are meristematic.
The radicle and plumule length of test crops were measured and compared with those of control.

This exercise is introduced with a description of seedling morphology, including root hairs, cotyledons, hypocotyl, epicotyl and plumule.
Pigmentation of the plumule and leaf sheath was assessed on a 1-to-5 rating scale (1 = plumule or leaf sheath with a deep pink pigment, 2 = plumule or leaf sheath with a pink pigment, 3 = plumule or leaf sheath with light pink pigment, 4 = plumule or leaf sheath with very light pink pigment, 5 = plumule or leaf sheath of green color) at 5 DAE.
5, 1, 3, 6, 12 and 24 h in different combinations, either to plumule or radicle or both parts of the propagules of Rhizophora mucronata Poir (sample size = 30).
