| Description |
Kernels
grown within loosened glumes in three varieties of paddy were darker in color and had a smoother
surface than those grown under normal conditions. The thickness of the pericarp p/us seed coat
layers was 33.6 + 2.8 urn, and the thickness of the aleurone layers was 21.7 +_ 2.5 #m in grains
of the first type, while in the normal grains, these dimensions were 13.0 +_ 1.4 and 26.9 +_ 2.9
lzm respectively. The kernels which developed within loosened glumes tended to taper towards
the distal end. They were lighter in weight than normal grains by 32 to 67 percent, the weight
loss being less in the bolder variety. The lemma-palea interlocking depth was positively correlated
with the groove depth on the kernel and with the clearance between husk and kernel. All three
parameters showed a positive correlation with grain breadth. A low lemma-palea interlocking
depth and a smaller clearance between husk and kernel are technologically desirable characteristics
in rice. The reclasping of the two glume components after pollination was essential for the
normal development of the rice grain.
