Title

Effects of Metolachlor on Germination, Growth, Leucine Uptake, and Protein Synthesis

P. Pillai; D. E. Davis; B. Truelove Weed Science 1979. doi:10.1017/s0043174500046038

Other claims from this paper (19)

Intervention effect At 10 -3 M, metolachlor reduced germination by less than 10% in corn, English pea and sicklepod.
Intervention effect At 10 -3 M, metolachlor reduced wheat germination by less than 10%.
Intervention effect At 10 -3 M, oat germination fell to 0.
Intervention effect At 10 -3 M, lettuce germination fell to 11%.
Intervention effect At 10 -3 M, peanut germination fell to 14%.
Intervention effect A 10 -6 M metolachlor concentration did not affect germination of tested species.
Intervention effect A 10 -5 M concentration did not significantly decrease corn, morningglory or wheat root length and fresh weight.
Intervention effect At 10 -5 M, metolachlor adversely affected other tested species.
Intervention effect At 10 -5 M, English pea root length was less than two-thirds of control.
Intervention effect At 10 -5 M, cucumber root length was less than two-thirds of control.
Intervention effect At 10 -5 M, radish root length was less than two-thirds of control.
Intervention effect At 10 -5 M, sicklepod root length was less than two-thirds of control.
Intervention effect At 10 -5 M, soybean root length was less than two-thirds of control.
Intervention effect One kg/ha in the shoot zone significantly reduced barley seedling height and dry weight.
Intervention effect One kg/ha in the shoot zone significantly reduced corn seedling height and dry weight.
Intervention effect Shoot-zone treatment was ineffective in the seed or root zone, while all-zone treatment was about twice as detrimental.
Intervention effect Four kg/ha in all zones decreased English pea seedling height and dry weight about 98%.
Intervention effect At 10 -5 M, metolachlor decreased leucine uptake in cucumber root tips but not incorporation into protein.
Intervention effect At 10 -4 M, metolachlor strongly reduced leucine uptake and slightly decreased incorporation into protein.

Title

The Role of Cotyledons in Growth and Photosynthesis of Radish Plants

Shigetoshi SUZUKI Journal of the Japanese Society for Horticultural Science 1976. doi:10.2503/jjshs.45.275

Other claims from this paper (10)

Intervention effect Excising cotyledons at an early stage decreased radish plant growth.
Observation Dry weight of cotyledons decreased in the dark.
Observation Dry weight of the other organs increased in the dark.
Observation Dry weight of every organ increased in the light.
Intervention effect In decotylized plants grown in the light, dry weight of hypocotyls and roots decreased.
Observation The foliage leaves are the strongest sink among the radish organs.
Observation The growth phase of the Rapid Red radish cultivar can be divided into two periods.
Mechanism Growth of foliage leaves in phase 1 is enhanced by reserve materials and photosynthetic products supplied from cotyledons.
Mechanism Hypocotyl growth in phase 2 is caused by a sufficient supply of photosynthetic products from foliage leaves.
Mechanism The decrease in radish growth caused by decotylization is due to the decrease in foliage leaf growth.
