Photoreversibility of Flower Initiation.
A. Borthwick et al (4) recently demonstrated that the red reaction inducing the germination of lightsensitive lettuce seed could be reversed. Their studies show that far-red near 7350 A is the region of maximum effectiveness in reversing the red reaction and thereby inhibiting seed germination. Thus, seed irradiated with red are put into a germinating condition that is nullified or reversed if ...
متن کاملInheritance of flower color in chickpea.
Flower color is a useful morphological marker in chickpea (Cicer arietinum L.). Inheritance of this trait was studied using two white-flowered chickpea genotypes, P 9623 and RS 11, and one blue-flowered genotype, T 39-1. The genetic constitutions of the white flower colors of P 9623 and RS 11 were different, for in an earlier study their F1 produced pink flowers. The two F1s of the crosses P 96...
متن کاملThe Sorghum Photoperiod Sensitivity Gene , Ma , , Encodes a Phytochrome B '
The Ma, gene is one of six genes that regulate the photoperiodic sensitivity of flowering in sorghum (Sorghum bicolor [L.] Moench). The masR mutation of this gene causes a phenotype that is similar to plants that are known to lack phytochrome B, and masR sorghum lacks a 123-kD phytochrome that predominates in light-grown plants and that is present in non-magR plants. A population segregating fo...
متن کاملThe sorghum photoperiod sensitivity gene, Ma3, encodes a phytochrome B.
The Ma3 gene is one of six genes that regulate the photoperiodic sensitivity of flowering in sorghum (Sorghum bicolor [L.] Moench). The ma3R mutation of this gene causes a phenotype that is similar to plants that are known to lack phytochrome B, and ma3 sorghum lacks a 123-KD phytochrome that predominates in light-grown plants and that is present in non-ma3 plants. A population segregating for ...
متن کاملInheritance of Resistance to Sorghum Shoot Fly, Atherigona soccata in Sorghum, Sorghum bicolor (L.) Moench
Sorghum production is affected by a wide array of biotic constraints, of which sorghum shoot fly, Atherigona soccata is the most important pest, which severely damages the sorghum crop during the seedling stage. Host plant resistance is one of the major components to control sorghum shoot fly, A. soccata. To understand the nature of gene action for inheritance of shoot fly resistance, we evalua...
