TL;DR: The antimicrobial activities of the crude juices of Allium sativum, Allium cepa, Raphanus sativus have been found to be strongly active on Escherichia coli, Pseudomonas pyocyaneus, Salmonella typhi andBacillus subtilis, while the crude juice ofCapsicum frutenscens andEruca sativa were active only onEscherichian coli.

The crude juice ofAllium kurrat was active onEscherichia coli andBacillus subtilis. The active antibacterial substances were easily isolated by different organic solvents.

TL;DR: It was concluded that the long-distance transport of IAA from the apical bud of intact pea seedlings does not take place in the phloem sieve tubes involved in the transport of metabolites from foliage leaves, or in the non-living tissues of the xylem.
Abstract: When small colonies of the pea aphid [Acyrthosiphon pisum (Harris)] were established on the stem of Meteor Dwarf Pea seedlings (Pisum sativum L.), 14C was found in the honeydew 4.5 h after applying IAA-1-14C to a fully-expanded foliage leaf. In contrast, no activity was found in the honeydew or aphids 4.5 h after the application of IAA-1-14C to the intact apical bud even though the internode upon which the aphids were feeding contained high levels of 14C. The lack of radio-activity in aphids feeding on stems to which IAA-1-14C was applied via the apical bud was found not to be influenced by the internode position or by the transport interval allowed (up to 24 h).

TL;DR: Evidence from light- and dark-grown peas does not support the concepts that differences in ABA are associated with differences in height or that ABA is a correlative inhibitor of stem elongation.
Abstract: Wilting tall or dwarf peas produced a marked increase in abscisic acid (ABA). Evidence from light- and dark-grown peas does not support the concepts that differences in ABA are associated with differences in height or that ABA is a correlative inhibitor of stem elongation.

TL;DR: Nodulation of inoculated pea plants was severely inhibited when ethrel (2-chloroethane phosphonic acid) was applied to the roots, and part of the effect of ethrel on nodulation came from its inhibition of root growth.
Abstract: Nodulation of inoculated pea plants was severely inhibited when ethrel (2-chloroethane phosphonic acid) was applied to the roots. The inhibition was evident at ethrel concentrations of 2 ppm and above. Ethrel applied to the foliage at 10 ppm also depressed nodulation. At least part of the effect of ethrel on nodulation came from its inhibition of root growth.

TL;DR: It is suggested that auxin produced by the shoot may influence the growth and development of the root system of Pisum sativum L. cv.
Abstract: Summary The effect of auxin of shoot origin on the growth and development of the root system of Pisum sativum L. cv. Kelvedon Wonder was investigated. Root growth was reduced when auxin transport from shoot to root was interrupted, but this could have been caused by a reduction in assimilate supply rather than a deficiency of auxin. Shoot removal, however, markedly reduced the number and total length of secondary roots produced and a 1% IAA–lanolin paste applied to the cut stump compensated to a large extent for shoot removal, markedly increasing secondary root growth in de-shooted plants. It is suggested that auxin produced by the shoot may influence the growth and development of the root system.

TL;DR: The anthocyanins and flavones present in different colour forms of Pisum sativum have been identified and related to the genetic constitution of the plants and Variation of genetic expression in different tissues of the plant is demonstrated.

TL;DR: A method was developed for partial purification of the B-protein of tryptophan synthase (EC 4.2.1.20) from pea plants and the partially purified B- protein, in the absence of A-protein, catalyzed the condensation of indole and serine to tryptophile at an appreciable rate.
Abstract: A method was developed for partial purification of the B-protein of tryptophan synthase (EC 4.2.1.20) from pea plants. The enzyme was purified 28-fold with about 21% recovery. The purification proc...

TL;DR: The physicochemical properties and fatty acid composition of the oils of the seeds of L. sativum, Eruca sativa, and Thlaspi arvense, with oil contents of 23.08, 33.46, and 29.18%, respectively, have been determined as discussed by the authors.
Abstract: The physicochemical properties and fatty-acid composition of the oils of the seeds ofLepidium sativum, Eruca sativa, andThlaspi arvense, with oil contents of 23.08%, 33.46%, and 29.18%, respectively, have been determined. The amounts of erucic acid, which is characteristic for Cruciferae, found were 4.71% in the oil ofL. sativum, 37.18% in that ofE. sativa, and 23.04% in that ofTh. arvense.

TL;DR: In this paper, inactivation of lipoxygenase from peas (Pisum Sativum L) was reported. But the authors did not consider the influence of substrate and reaction products.

Journal ArticleDOI
TL;DR: This work has studied the relation between oxidation of unsaturated higher fatty acids and changes in the localization of intracellular lipoxygenase in plant tissues and found it to be similar to that of animals.

TL;DR: The yield of a plant is the product of interation within a number of characters, as well as with the environment; hence the inheritance of yield is a complex character.

Journal ArticleDOI
TL;DR: Pea dry seeds treated with X-rays and with homogeneous magnetic field were observed for several effects during the development of the plants, and the changes of the first stages of growth are considered to be due to physiological changes stressed by the meristematic proteins with different iso-electric point.

TL;DR: A comparison of different pea cultivars showed a positive correlation between the Chl content of the seeds and that of their embryonic axes, and a attempt was made to determine in which way chlorophylls are accumulated during the development of the embryonic stage.
Abstract: SUMMARY Leaves of dark grown seedlings of Pisum sativum L. cv. ‘Krombek’ contain both chlorophyll-a (Chl-a) and Chl-b in significant amounts. These pigments are not synthesized during seedling growth in darkness, but are already present in the embryonic axis. A comparison of different pea cultivars showed a positive correlation between the Chl content of the seeds and that of their embryonic axes. We have not attempted, however, to determine in which way chlorophylls are accumulated during the development of the embryonic stage.
