Pablo’s Background

Tropical man

Vegetable and fruit crops

Growth regulation, nutrition, protection
Pablo’s mandate

Teaching and research

Tropical and subtropical fruit crops
(what this workshop covers, +citrus
+watermelon & melon, -banana & other
Musa)
Fruit crops with largest acreage

Avocado
Pineapple
Mango
Orange and tangerine
Banana
Fruit crops with smaller acreage

Papaya
Quenepa (Spanish lime)
Passion fruit
Fruit crops coming up

Quenepa (Spanish lime)
Sapindaceae (lychee, rambutan…)
Mangosteen
Giant granadilla
Pitahaya
Interest in peach and plum for the
highlands
Passiflora quadrangularis
Spanish lime or quenepa




       Melicoccus bijugatus
My research interests

Tendency to applied research

Problem-solving or system enhancing

Production and applied physiology

Protection
My interests
Influence of growth and other physiological
regulators on yield and quality

Interactions PGR x mineral nutrients

Physiological implications of antagonistic
organisms/SAR and environmental stress

Physiological regulation in organic and quasi-
organic systems
   Projects or Research Interests

Influence of growth regulators and mineral nutrients in
   organic and conventional systems on:
   1. Transplant production and vegetative
   propagation
   2. Manipulation of flowering, crop yield, and
   grade
   3. Diseases and weeds on crop physiology and
   its manipulation
   4. Post-harvest physiology (as a result of pre-
   harvest manipulation). Interest as a
   collaborator.
   Projects or Research Interests

1. Transplant production and vegetative
   propagation
   - To increase the production of pineapple
   propagation material*
   - To reduce nursery time in other crops*
   Projects or Research Interests

2. Manipulation of flowering, crop yield, and
   grade
   - To increase fruit set, retention, size, and quality
   attributes (mango, avocado, granadilla, low-chill
   peach and plum)
   - To enhance fruit size and quality (pineapple)
   - To manage alternate bearing (tangerine, Spanish
   lime, other crops)
Projects or Research Interests
3. Diseases and weeds on crop physiology and
its manipulation
- To enhance the competitive ability of crops with
weeds
- To enhance crop tolerance to diseases (avocado,
mango, papaya) by SAR
4. Post-harvest physiology (as a result of pre-
harvest manipulation). Interest as a
collaborator.
- To enhance fruit quality
- To extend post-harvest life
   Active, funded projects
Organic & synthetic mulches and a biological
herbicide to suppress nutsedge in watermelon

Growth regulators to enhance the production
of vegetative propagules in pineapple without
affecting fruit yield

Organic and synthetic biostimulants to reduce
citrus and mango time in nursery
     Prioritized proposed future
          research projects
1. Impact of growth regulators and nutrients on
phenology, carbohydrate budget, and alternate
bearing in avocado, Spanish lime, and tangerine.

2. Physiological and practical effects of SAR elicitors
on avocado and papaya tolerance to Phytophthora
and other soil pathogens.

4. Pruning and growth regulators to manage
flowering, fruit set, size, and quality in low chill peach
and plum.
Collaboration:    Very interested.
