Effect of Seed Priming on Germination, Field Emergence and Yield in Carrot (Daucus carota L.) / K. K. Paudel in Nepalese Horticulture, v. 10: 1 ([07/25/2015])
[article]
Title : Effect of Seed Priming on Germination, Field Emergence and Yield in Carrot (Daucus carota L.) Material Type: printed text Authors: K. K. Paudel, Author ; Shakya, S.M., Author ; M.D Sharma, Author ; K.R Dahal, Author Publication Date: 2015 Article on page: 16-26 p. Languages : English (eng) Keywords: Carrot, priming, germination, emergence, vigor Abstract: A field experiment was carried out at Rampur, Chitwan in split-plot design to study
the effect of priming of carrot seed on germination, early emergence, field
emergence, plant stand establishment and root yield and quality. The treatments
consisted of two commercial varieties of carrot (New Kuroda and Nantes Fancy)
as main plot and seven levels of seed priming as sub-plots with 3 replications. The
treatment imposed seeds for the field experiment were also used for laboratory
test with four replications. New Kuroda exhibited higher vigor index (637.2),
faster early emergence (8.33 days), highest field emergence (56.33%) and plant
stand (66.67%), thickest cortex diameter (1.70 cm) and higher economic yield of
22.13 t ha-1 (50.65% more than control) in 24 hrs. seed soaking in tap water than
in non-primed seeds where as Nantes Fancy showed faster early emergence (8.66
days), highest field emergence (55.33%), higher plant stand (69.33%) and higher
yield of 17.69 t ha-1 (9.94% more than control) in 12 hrs. seed soaking in 400 C
warm water.

Title : Identification of Factors Causing Poor and Irregular Germination in Large Cardamom Seed (Amomum subulatum Rox.) Material Type: printed text Authors: Neelam Subba, Author ; Keshab Ghimire, Author ; Purushottam P. Khatiwada, Author ; Jyala Bajracharya, Author ; Sharmila Piya, Author Pagination: 220-226 p. Languages : English (eng) Keywords: Amomum subulatum, poor and irregular germination, embryo immaturity,
oxygen impermeabilityAbstract: Large cardamom seed remain dormant for six to eight months in field conditions. In
addition, poor and irregular germination is the major problem in nursery raising of large
cardamom. Different factors causing dormancy were studied in 2062/63-2063/64 at
Agricultural Research Station, Pakhribas and Seed Technology Research Division,
Khumaltar. Large Cardamom cv. Ramsahi was subjected to following hypothesis;
dormancy due to poor water permeability, poor oxygen exchange, presen_s;e- of water
soluble inhibitors, embryo immaturity or a combination of more than one factors. Hard
seed coat did not impose significant barriers to moisture uptake in large cardamom
seed. Different dormancy relieving treatments to test the above hypothesis differed
significantly in number of germinated seed placed in alternating temperature regime of
30°C and 200C for 8 and 16/:Jrs respectively. Earliest germination within 30 days was
I
observed in seed treated for embryo maturation and oxygen permeability and highest
percent germination (66%} was observed in the first four months in seed treated for
oxygen permeability. Seed treated for oxygen permeability after 3 minutes scarification
with uniform sized gravels when sown in nursery showed > 40% germination in field in
the first four months. It can be concluded that not one but the combination of above
mentioned factors are responsible for causing dormancy in large cardamom.Identification of Factors Causing Poor and Irregular Germination in Large Cardamom Seed (Amomum subulatum Rox.)
