Central Institute for Subtropical Horticulture, Lucknow, a
constituent body under the Indian Council of Agriculture Research,
New Delhi takes pride in organizing a three days' “National Seminarcum-Workshop on Physiology of Flowering in Perennial Fruit
Crops” from April 19-21, 2014 at its main campus in Rehmankhera,
India, acclaimed for its rich genetic diversity of mango, has also
assembled reasonably good amount of variability at different centers
of NARES in respect of other perennial fruit crops viz., citrus, grapes,
guava, banana, aonla, bael, litchi, jamun, several underutilized and
temperate fruits for crop improvement. This effort has over the years
resulted in development of some trait-specific varieties which are
gradually entering into the production system across the country.
Fruit culture, has always been looked upon as one of the potential
options for diversification in horticulture for ensuring sustainable
livelihood options and efficient land use patterns as it is relatively less
affected by weather vagaries as of now, thereby paving the way for
heralding “Golden Revolution”. Fruits, besides being sources of
nutritional-cum-nutraceutical principles, now find prominent place in
the family food baskets from health perspectives which provide
ample opportunities for profitable fruit culture in the sub-continent.
Wide range of fruits from tropical, temperate, arid and fruits of the
cold deserts though are being grown across diverse agro-eclogies,
with considerable success, prevailing wide gaps in their productivity
as compared to that of other producing countries offer challenges to
scientists. Apparently, these gaps largely prevail due to variations in
flowering and fruit set events occurring across different agroecologies that need to be addressed.
Flowering is the major phenological event that exerts direct
influence on the fruit production tendencies and several times there
also ensue contrasting issues of prolific flowering with no appreciable
fruit set. In fruit crops, there is lack of information on natural
variations in gene expression, and even less is known about the
functional significance of the existing gene expression variations in
relation to flowering. Understanding of specific genes involved in
control of flowering, and climate resilience are thus crucial for
deciphering the functional significance of gene expression. Genome
assembly, assisted localization of flowering and comparison of
hormone-related genes and their positioning with QTLs appear to be
promising strategies in order to understand the biennial bearing
tendencies across fruit crops. Earlier, researches though have inferred
that flowering genes are less likely to be responsible for biennial
bearing than the plant growth hormone-related genes which are either
down or up regulated in response to environmental cues, their
delineation hence becomes imperative. Quantitative genetics of
phenology in fruit crops though to some extent has generated
considerable interest in the recent years, yet the genes that underline
different traits associated are largely unclear. This complex biological
phenomenon is even less understood in perennial tropical and
subtropical fruit crops although considerable leads are available in the
annuals and temperate fruits. Further, the physiological basis of
phenological variations especially the root signals, carbon
partitioning priorities, carbon assimilation and transformation,
hormonal interpolations, etc., in regulating flowering phenology
especially need elucidation for management of flowering. Therefore
it has become imperative to hold this national seminar in order to
deliberate upon the important issues concerning flowering. The
relationship between ideotype and tree architecture management and
alternate bearing including climate resilience needs to be discussed
for developing strategies for regulation of flowering at will in
perennial fruit crops.
The programme will include thematic interactive lectures and
panel discussion with experts covering different aspects of flowering
physiology in perennial fruit crops on the following broad areas:
1. Physiological and biochemical basis of environmental
regulation of flower induction in perennial fruit crops
2. Molecular events during flower induction
3. Shoot maturity, canopy architecture
management and
horticulture interventions in relation to regulation of flowering
4. Climate change paradigms and likely impacts on flowering
The relevant thematic topics on the major aspects in this regard
pertaining to perennial fruit crops are briefly summarized below. The
organizers invite focused research articles/abstracts/poster materials
on the following:
1. Physiological and biochemical basis of environmental
regulation of flower induction.
a. Temperature and flower bud differentiation
Physiological basis of high and low temperature effects on
b. Water stress on flower induction
Physiology and biochemistry of water stress induced
flower bud differentiation. The effects of water stress on
C/N ratio, hormones etc. associated with flowering
c. Photoperiods, temperature dynamism and flower bud
Phytochromes, Cryptochromes; molecular basis of
regulation of flowering under the influence of photoperiod
and temperature
2. Molecular events during flower induction
a. Present concepts about the genes involved in signal
perception, transduction on flower bud differentiation
b. Regulation of flowering by expressing relevant genes
c. Markers / QTLs associated with flowering / flowering
3. Shoot maturity, canopy management in relation to flowering
a. Physiology of shoot maturity, hormones and molecular
events during shoot maturation.
b. Canopy management and effects of pruning on flowering
c. Physiology and molecular basis of alternate bearing
d. Induction of flowering by chemicals / hormones
e. Nutrition and flowering
Climate change and likely effects on flowering
a. Future projections on the flowering and fruiting behavior in
perennial fruit crops grown in different agro climatic
regions due to climate change
b. Biotic and abiotic factors affecting flowering under the
influence of climate change
Poster Presentation
There will be poster sessions covering the theme areas to
encourage wider presentations and discussion. The extended
summaries contributed for oral presentation and poster sessions will
have a convener and a co-convener, who will prepare and present
summary at the end of concerned session permitting focused
discussion and facilitate formulation of recommendations.

About The Institute
The Central Institute for Subtropical Horticulture (CISH),
Lucknow a premier research institute under the Indian Council of
Agricultural Research, New Delhi is carrying out research work on
different aspects of subtropical fruits viz., mango, guava, papaya,
aonla, bael and some underutilized fruits for improving productivity
and profitability. It is located on Lucknow-Hardoi Road at
Rehmankhera in the vicinity of Kakori and Malihabad, the famous
'Dashehari' mango belt of Uttar Pradesh. The experimental farms of
the institute are spread over in an area of 132.5 ha. housing the world's
largest mango field gene bank . The period of the event coincides with
the fruit set and development process in the mango genetic diversity.
The Institute with well equipped infrastructure and scientific
expertise also holds pride for the conservation of genetic resources in
the field gene bank of other subtropical fruits viz., guava, jamun,
aonla, bael and litchi as well. CISH, Lucknow is also presently,
recognized DUS Centre by PPV&RA, New Delhi for mango, guava,
Jamun and bael.
About Lucknow
The historic city of Lucknow, sprawling on the banks of the holy
river Gomti, is famous for its rich cultural heritage and warm
hospitality. The 'Bara Imambara', built by the Nawab Asaf-UdDaulah is famous for its maze of labyrinths, known as the 'Bhool
Bhulaiya'. The city is also famous for its Mughlai cuisine, Chikan and
Zardozi embroidery, and brass, Bidri stone wares and wood carvings.
The event period coincides with the onset of summer, which will
be largely pleasant. The temperature in Lucknow during the period is
