1), and they could then be located by sorting through old leaf sheaths
near new growth.
Chen HJ, Wang SJ (2008) Molecular regulation of sink-source transition in rice leaf sheaths
during heading period.
A woman "decorticates" the leaf sheaths
by holding them against an inclined wooden plank, sometimes with her leg, while using a bamboo scraper to remove the fleshy pulp of the sheath.
V1= Height of the plant; V2= Number of tillers per plant; V3= Number of fertile branches per plant; V4= Number of leaves on main tiller; V5= Length of inflorescence (cm); V6= Number of internodes on main tiller; V7= Flag leaf area (cm2); V8= 4th node leaf area of main tiller (cm2); V9= Length of internode covered by leaf sheath
at 4th node (cm); V10= Thickness of stem at 4th node of main tiller (mm); V11= Number of spikelets per inflorescence
In this instance, those changes could include attack by any one of the four biocontrol agents--the wasp, scale, fly, or leaf sheath
The intensity of leaf sheath
and plumule pigmentation was greater for shoot fly-resistant CMS, maintainer, and restorer lines as compared with the susceptible ones (Table 1).
Mahanarva posticata lays its eggs in the leaf sheaths
(Mendonca et al.
Auricles Clawlike appendages that project from the collar where the leaf sheath
and blade join.
Leaves 2, reduced to tubular sheaths; upper leaf sheath
up to 15 cm long, membranous-translucent, loose but not inflated, friable, often splitting adaxially, stramineous to pale grayish brown, apex obtuse to subacute, not callose, tooth-like projection (mucro) absent or very short; lower leaf sheath
much shorter than upper, membranous, dark grayish brown to almost black.
Plant color at boot stage (Feekes growth stage 9-10) is blue green and a waxy bloom is present on the stem and flag leaf sheath
But control has been difficult because the pest's eggs are tucked between the plant's leaf sheath
and stalk, where both eggs and larvae are protected from chemical sprays.
Samples were separated into leaf blade, stem including leaf sheath
, and dead fraction of tissue similar to the methodology used by Coyne and Bradford (1985).
