Detailed Description:

Purple Paro Valley was developed from a landrace Sativa that originates from the Paro Valley in West Bhutan at an altitude of 2.500 meters. The feminised hybrid is only two generations removed from the wild habitat. In this region the landrace has adapted to the harsh Himalayan climate of extended dry spells, monsoon rain, and cold winters. Purple Paro Valley (PPV) is recommended for cultivation in northern climates up to 56°N, or where high humidity is a concern. With global warming making outdoor cultivation increasingly unpredictable this resilient landrace hybrid can meet the challenge.

Thanks to her extreme durability she can cope with low temperatures better than most modern cannabis strains. At first glance her flexible branches look somewhat fragile and willowy. But the local Paro landrace can withstand strong wind and downpours. For the most part, Purple Paro Valley has inherited this feature. Nevertheless, it is recommended to support the plants if a storm is expected and not to wait and see! The mold resistance of the pure landrace and PPV is exceptionally high. The plants are also quite nutrient-efficient. Hybridising the landrace was essential to improve yield. Growing a large multi-branch plant will enhance yield further. Purple Paro Valley is especially suitable as a “back-up strain” in unfavourable climates. For example, a few PPV plants can be combined with a higher yielding strain for the north such as our Mandala #1. In very difficult locations, or in a season with exceptionally bad weather, Purple Paro Valley is perhaps the only reliable choice. Where other varieties have already failed before, there is still hope with this special strain! For guerrilla cultivation she is also an attractive choice because hardly any other strain requires such low maintenance.

Although the mother genetics are homogenous it did not turn out this way with the current feminised strain. This doesn’t have to be an undesirable factor. Diversity is an evolutionary strategy in nature to ensure survival. For that purpose, the diversity in PPV can play an important role in securing your harvest. We differentiate mainly between the green and the purple phenotype. The purple phenotype accounts for approx. 75% per 10 seeds and is very attractive and fascinating to watch during flowering. The green pheno is shorter in height, finishes flowering earlier, and the buds are also more compact. The purple plants have long internodes, which has to be taken into account when growing in containers or a greenhouse. Late planting and pruning is recommended in both situations. In a Mediterranean or hot climate the plants grow between 1.50 (green pheno) to 2 meters in containers if they are planted in June (northern hemisphere) and left unpruned. If a moderate size is desired, we recommend timing the planting season to allow for just one month vegetative growth. During this vegetative period pruning the main growing tip once should be sufficient. Purple Paro Valley responds well to LST (low stress training). Trimming the bottom shoots further simplifies plant care and increases the strength of the upper branches.

During flowering most plants develop a delicious spicy and green lime aroma. The citrus/lime scent is typical of the Paro landrace. But there is one type of plant that stands out and we call her “candy girl”, because she smells just like sugary candy! When you crumble the dry buds they release a sweet, minty scent with a touch of hazelnut. The green phenotype tends towards lavender. The terpene linalool is responsible for the lavender scent and enhances the sedative, sleep enhancing effects, as well contributing to pain relief. Some of the purple plants can also smell like black tea, but the smoke still leaves a fresh, minty aftertaste on the exhale. PPV hash oil has the fresh, sweet, balsamic aroma of Himalayan cedar wood and has tested at 27,5% THC. The high is predominantly very relaxing or couch lock. It’s suitable for winding down, as a sleep aid, great to relieve hyperactivity and nervousness.

Crop rotation and residue incorporation will reduce inoculum by breaking down infested residue.

Purple Seed Stain and Cercospora Blight

Loren J. Giesler, Extension Plant Pathologist

Pathogen

Purple Seed Stain (Cercospora blight) is caused by the fungus Cercospora kikuchii. It is also known by the names purple blotch, purple speck, purple spot or lavender spot. Purple seed stain infection of the seed does not directly reduce yield. However, if a high percentage of stained seed is harvested, grain dockage may occur or seed certification may be denied. Delayed germination may occur when seed discoloration exceeds 50% of the seed coat. The inoculum source for this disease is infected seed and debris from previous soybean crops.

Disease Symptoms

Symptoms of purple seed stain are usually expressed in the seed. Infected seeds may appear healthy or have pink to purple spots that range in size from specks to large blotches that cover the entire surface. The discoloration extends from the seed hilum in all cases. Yield is not affected by the seed phase of the disease but the value of crop is lessened when it is downgraded due to the color variation. Seeds with a very high percentage of discoloration have lower oil content and higher protein content compared to healthy seed. Germination and seedling emergence is lower from purple seed stain infected seeds than from those that are healthy. Germination affects are often a delayed germination or smaller seedling. Cotyledons of infected seedlings shrivel, turn purple and drop.

The leaf blight phase may be evident at the beginning of seed set. Young leaves on the upper portion of the plant are affected and have a dark reddish purple bronzing. Leaves will have irregular shaped reddish purple lesions that vary in size from small specks to spots that are ½ inch in diameter. Lesions occur on both upper and lower leaf surfaces. Large necrotic blotches form when the lesions coalesce and veinal necrosis may also be evident. Severely affected upper leaves are often shed with the petioles being held on the plant and the lower leaves remain attached. Infection sites on petioles and stems are sunken red lesions that can be up to ¼ inch in length.

Favorable Environmental Conditions

Purple seed stain fungi sporulation occurs under conditions of high humidity and temperatures of 73-80°F. Initial infections are often latent and do not appear visible until the R4 growth stage.

Sporulation studies have shown increases in spores with the amount of days with average air temperatures above 82 F.Seed infection in generally not limited by weather factors once initial infections have occurred.

Management

Genetic Resistance

Soybean varieties vary in their response to this fungus and it is thought that resistance to leaf and seed infections are under different genetic control

Cultural Practices

Crop rotation and residue incorporation will reduce inoculum by breaking down infested residue.

Chemical/Biological Control

Seed lots with a high percentage of infected seed should be treated with a seed treatment fungicide. Foliar fungicides may be applied during early pod stages R3-R5 to prevent blight and pod infections.
