PLANT MORPHOLOGY

 

 

 

Plant form Tree.

Mature plant growth habit

Prostrate (to be recorded in fully mature plants)

Branching habit

Dense (recorded simultaneously with plant height)

Thorniness

Absent(Recorded the comparative thorn density on mature Plant).

Branching of thorn

Non-branched (Recorded simultaneously with plant height).

 

Immature steam colour light brown (Recorded on immature stem, 5cm before the stem tip – Rusty Brown).
Mature steam colour Brown, other (Recorded on main stem, 25 cm above the soil).
Silver scale on steam Absent (Recorded on new shoot growth), Present.
Stellate hairiness on 0,1,3
Stem bark -
Young branches -

Stem shape

Rounded (Recorded from the main branch, 15cm above the soil).

   

QUANTITATIVE CHARACTERS

 

 

 

Plant height (cm) 4-5 (Recorded as the length from soil level to topmost portion in the canopy centre exactly above the main trunk).

Canopy width (cm)

3 cm(recorded simultaneously with plant height as the max.  Canopy diagonal in a horizontal planes –Two directions East-West and North-South).

Inter-branch distance

Record the mean distance between 5 mature branches from the main stem at base of the plant above 30 cm ground. This character is recommended only when the accessions under evolution have a common geographical origin, otherwise the different rate induced by varying growth condition will not represent the true genetic variability.

   

LEAF CHARACTERS

 

 

 

No. of leaves attached at single point One (To be recorded at immature fruit stage)

Upper Leaf Surface (Adaxial Side)

Rough, Leathery (Recorded at immature fruit stage).

Lower Leaf Surface (Adaxial Side) Glabrous
Colour of abaxial side Green-yellow.
Colour of leaf midrib on the abaxial side Cream,Yellow  green (to be recorded at green fruit stage).
Phyllotaxy (arrangement of leaves) Spirally whorled(Recorded on the 10cm of branch).
Adaxial leaf surface colour Rusty Brown Light green (Present of Rusty Brown in all the area of leaf)
Leaf tip Shape Curved inward.
Leaf margins

Smooth.

Leaf senescence nature Deciduous.
Stellate hair beneath the leaves Present.(brown Colour)
Leaf attachment to stem Pedicellate

Sliver scales on the leaves

Absent.

Leaf venation Reticulate.

QUANTITATIVE CHARACTERS

 

 

 

Leaf Length (cm) 1.375 cm (Recorded as mean length of 10 leaves from the base of secondary fruit bearing branches. Length is measured from the base to the tip of the leaf blade).
Leaf width (cm) 0.7 cm (To be recorded on the same leaves used for the measurement of leaf length. Width is measured at the widest portion of the leaf).
