Kinetin alleviates cycloheximide inhibition and oxygen alleviates chloramphenicol inibition of germination of lettuce seeds (Lactuca sativa L. cv Grand Rapids). The effect is not due to increased but rather a substitution for protein synthesis. A cytokinin and energy supply appear prime requirements for germination.

one of the crucial issues before the second cropping is having enough knowledge about the residue effect of first crop herbicides on second crops. this experiment was conducted to investigate the possible inhibitory effect of some selective paddy herbicides residues to second cropping. experimental factors were included common paddy herbicides (thiobencarb, butachlor, oxadiargyl, bensulfuronmet...

Allelopathy between Mucuna pruriens (velvet bean) and Lactuca sativa (lettuce) was studied under 3D-clinorotation. Growth of both roots and shoots of lettuce seedlings was suppressed by the presence of velvet bean. The degree of suppression was less on the clinostat compared to the normal static earth gravity. L-DOPA (L-3, 4-dihydroxyphenylalanine) is known to be a major substance in allelopath...

a two year field experiment was carried out to evaluate the effects of municipal waste compost (c), composted cattle manure (m), and nitrogen (n) on growth and composition of weeds in a corn field in shiraz using a split-split plot design with 3 replicates. visual inspection of the plots showed that the manure treatments neither introduced new weed species nor increased weed density more than t...

Lettuce (Lactuca sativa L.) is extensively grown and is the most widely used food crop for the called “Fourth Range” of vegetables. Lettuce exhibits healthy properties mainly due to the presence of antioxidant compounds (vitamins C and E, carotenoids, polyphenols) alongside significant fibre content and useful amounts of certain minerals. Lettuce can establish a mutualistic association with arb...

Kaahu – Lactuca sativa L. is a large genus of annual or perennial herbs, chiefly of north temperate regions. About 25 species occur in India. All the species contain milky latex and the dried latex from some of them furnishes the drug lactucarium. Lactuca sativa L. (Asteraceae) is considered as the most important vegetable in the group of leafy vegetables. It is also extensively used as a fresh...
