Three samples of rapeseed, composed of high, medium, and low glucosinolate cultivars, were air-classified into various fractions and these fractions were subjected to chemical and biological evaluation. The dehulled fraction of the seed had higher protein and fat content and lower fiber content than the original seed. Digestible nitrogen (DN) and digestible energy (DE) content increased when the hull was removed. Net protein utilization was also higher in the dehulled seed than in the intact seed. No effects of glucosinolate level in the seed were noted with respect to DN or DE but feed consumption of chicks was increased on all tests when the low glucosinolate meal was fed.

Excised Embryos

Gibberellic acid (GA) at constant temperatures partially replaced the alternate temperatures required to break dormancy of intact seed of Bells of Ireland (Moluccella laevis L.). In the presence of GA optimum germination occurred at 10 °C. and declined to almost nil at 25 °C. When 2-naphthaleneacetic acid (NAA) at 10−5 M. was combined with GA the effect on germination at 20 °C. was synergistic. Higher concentrations of NAA antagonized the stimulatory effect of GA. All excised embryos germinated whether from chilled or unchilled seed. Embryos with attached endosperms from chilled seed showed a marked increase in germination over those from unchilled seed. GA induced 100 per cent germination of embryos with attached endosperms, irrespective of chilling, at 20 °C, but not at 25 °C. The presence of the pericarp completely prevented the germination of untreated seed at constant temperatures. Chilling whole seeds for 6 weeks at 5 °C. greatly enhanced penetration of external solutions to the embryo.

Various animals produce inviable eggs or egg-like structures called trophic eggs, which are presumed to be an extended maternal investment for the offspring. However, there is little knowledge about the ecological or physiological constraints associated with their evolutionary origin. Trophic eggs of the seminivorous subsocial burrower bug ( Canthophorus niveimarginatus ) have some unique characteristics. Trophic eggs are obligate for nymphal survival, and first-instar nymphs die without them. To identify the cause of nymphal death, we hypothesized that first-instar nymphs starve to death because they cannot feed on anything but trophic eggs. Although first-instar nymphs fed on artificially exposed endosperm did survive, nymphs that were provided with intact seed were not able to penetrate the seed vessel and starved to death. Another hypothesis that trophic eggs play a role in transferring the midgut symbiont, essential for survival in heteropteran bugs, from mother to offspring was rejected because almost all nymphs had retained the symbiont without feeding on trophic eggs. These results suggest that poor feeding capacity of the offspring is the cause of nymphal death, and the important constraint that promotes the evolution of the curious trophic egg system in C. niveimarginatus .

The present investigations “Studies on the effect of pre-sowing treatment and time of wedge grafting on production of saleable grafts in mango” were carried out in the nursery block of Fruit Science Department. The study was conducted using wild mangoes seeds. The seeds were divided in two equal halves, one half of seeds were sown with intact seed coat (K1) while, in other half the mango kernels were extracted (K2), both type of seeds were then soaked in 6 different chemicals of varying concentrations viz. C1- KNO3 @ 0.5%, C2- KNO3 @ 1%, C3- KNO3 @ 1.5%, C4- BA @ 50 ppm, C5- BA @ 100 ppm, C6- GA3 @ 100 ppm, C7- GA3 @ 200 ppm, C8- beejaaumrit @ 2%, C9- beejaaumrit @ 3%, C10- panchgavya @ 2%, C11- panchgavya @ 3% for 12 hours and C12- Control. The germination and vegetative parameters were observed. The results of study revealed that the e×tracted kernels pre-soaked with GA3 @ 100 ppm produced earliest germination, 50 % germination, high rate of germination, germination percentage, number of leaves, maximum leaf area, highest seedling vigour index, while, on pre-soaking extracted kernel with KNO3 @ 0.5% produced maximum seedling diameter. The Seedling raised from extracted kernels pre-soaked in KNO3 @ 0.5% (C1K2) attained graftable diameter within 210 days of sowing. The present investigation was conducted during 2019-2020 at the nursery block of College of Horticulture and Forestry, Neri Hamirpur (H.P) to study the effect of pre-sowing treatments on germination, growth and production of graft-able seedlings.

AbstractSolute leakage is used as an indicator of membrane damage during desiccation of recalcitrant seeds. We re-examined this phenomenon and its utility by comparing recalcitrantSpartina alternifloraand orthodoxSpartina pectinataseeds, as well as drying isolated embryos or embryos isolated after whole-seed drying. During drying, intact seed leakage (electrical conductivity and absorbance at 280 nm) was independent of seed moisture content, dormant/non-dormant state or desiccation tolerance. Embryos from bothSpartinaspecies, isolated after drying within the intact seed, exhibited increased leakage, especially below 40% (dry weight basis, DWB) seed moisture, the critical water content for viability loss inSpartina alterniflora. When isolated embryos were dried, the pattern and extent of increased solute leakage were similar in bothSpartinaspecies, even thoughS. pectinataembryos were >95% viable andS. alternifloraembryos were < 20% viable. We conclude that increased solute leakage is an artefact of embryo excision and not an accurate indicator of desiccation damage to recalcitrantSpartina alternifloraseeds.

Grand Rapids

The response to red and far-red light of intact and punched seeds of Lactuca sativa var. Grand Rapids is compared. Punched seeds are fully responsive to red light after only 1 min of hydration; intact seeds require 15 min. Punching has no effect on the usual red and far-red light mediation of germination of these seeds. It does, however, raise the level of dark germination, indicating that there are at least two mechanisms by which the seed can germinate, only one of which is controlled by phytochrome.Treatment of seeds with dichloromethane enhances germination in seeds imbibed 1 min but not the penetration of arsenate, which is normally excluded by the intact seed. The detergent Brij greatly enhances the penetration of arsenate into the seed.

Colonization and sporulation of aflatoxigenic Aspergillus flavus Link on intact and injured seed was evaluated for a selection of almond [Prunus dulcis (Mill.) D.A. Webb] cultivars. Barriers to fungal development were identified at the intact seedcoat and at the seed cotyledon tissue. The seedcoat barrier was expressed as a delay in fungal colonization for up to 3 days following the inoculation of intact seed. Seedcoat resistance was uniformly high for all cultivars tested. Cotyledon resistance, which was expressed as a lower rate of disease development was identified only in the cultivars Ne Plus Ultra, Ruby, and Carrion.
