Ratio of stem weight to root weight of soybean cultivars.

Genetic Control of Root Weight, Root Volume and Root to Shoot Weight Ratio in Peas

The genetic control of root weight, root volume and root to shoot weight ratio was studied in peas (Pisum sativum L.) at flowering. The four populations used were developed from crosses between lines and cultivars differing in size of the root systems. Plants of the F 1, F 2 , backcross and parental generations were evaluated in pots filled with soil: sand mixture, in a completely randomized de...

The Ratio of School Bag Weight to Body Weight and Its Relationship with some Factors in Elementary School Students of Gorgan, Iran, in 2013-14

Background: School age is a sensitive period in the child growth. Backpack weight has an important impact on physical growth and neuromuscular development of the children. Regarding this, the present study was conducted to determine the ratio of backpack weight to body weight and investigate its relationship with some factors among the elementary school students of Gorgan, Iran, within 2013-14....

Ratio and Weight Quantiles

Several types of weighted-automata models and formalisms to specify and verify constraints on accumulated weights have been studied in the past. The lack of monotonicity for weight functions with positive and negative values as well as for ratios of the accumulated values of non-negative weight functions renders many verification problems to be undecidable or computationally hard. Our contribut...

Response of two soybean cultivars to moisture stress

Resistance in Soybean Cultivars from Maturity Groups V-VIII to Soybean Cyst and Root-knot Nematodes.

One hundred thirty-nine cultivars of soybean (Glycine max) in Maturity Groups V, VI, VII, and VIII were evaluated in a greenhouse for resistance to Heterodera glycines races 3 and 14 and Meloidogyne incognita, M. arenaria, and M. javanica. Of the cultivars tested, 37% had resistance to H. glycines race 3 alone, 12% had resistance to both races 3 and 14, and 69% exhibited a moderate or high leve...
